This is more efficient and statisically more correct than doing a back and fourth of set_sampling_interval(0) and set_sampling_interval(RATE).

The release() method can be used on the returned object to release its ownership of the lock and avoid the automatic unlock. Note that both <a class="el" href="classseastar_1_1basic__rwlock.html#aa703d97200570e03894afc30f7d345a6">hold_read_lock()</a> and <a class="el" href="classseastar_1_1basic__rwlock.html#ac43c2f1e0e5615657be0d0963ad7f7c9">hold_write_lock()</a> return an object of the same type, rwlock::holder.</p>

+<p >This is a standard computer science semaphore, adapted for futures. You can deposit units into a counter, or take them away. Taking units from the counter may wait if not enough units are available.</p>
+<p >To support exceptional conditions, a <a class="el" href="classseastar_1_1basic__semaphore.html#af627627cf8b0aa84441c4c6d0013cc53">broken()</a> method is provided, which causes all current waiters to stop waiting, with an exceptional future returned. This allows causing all fibers that are blocked on a semaphore to continue. This is similar to POSIX's <code>pthread_cancel()</code>, with <a class="el" href="classseastar_1_1basic__semaphore.html#a30f599e383c15e039406500af0629083">wait()</a> acting as a cancellation point.</p>

+<p >Similar to libstdc++'s std::deque, except that it uses a single level store, and so is more efficient for simple stored items. Similar to boost::circular_buffer_space_optimized, except it uses uninitialized storage for unoccupied elements (and thus move/copy constructors instead of move/copy assignments, which are less efficient).</p>
+<p >The storage of the <a class="el" href="classseastar_1_1circular__buffer.html">circular_buffer</a> is expanded automatically in exponential increments. When adding new elements:</p><ul>
+<li>if size + 1 &gt; capacity: all iterators and references are invalidated,</li>
+<li>otherwise only the begin() or end() iterator is invalidated:<ul>
+<li>push_front() and emplace_front() will invalidate begin() and</li>
+<li>push_back() and emplace_back() will invalidate end().</li>
+</ul>
+</li>
+</ul>
+<p >Removing elements never invalidates any references and only invalidates begin() or end() iterators:</p><ul>
+<li>pop_front() will invalidate begin() and</li>
+<li>pop_back() will invalidate end().</li>
+</ul>
+<p >reserve() may also invalidate all iterators and references. </p>

+<div class="textblock"><p >Conditional variable. </p>
+<p >This is a standard computer science condition variable sans locking, since in seastar access to variables is atomic anyway, adapted for futures. You can wait for variable to be notified.</p>
+<p >To support exceptional conditions, a <a class="el" href="classseastar_1_1condition__variable.html#ada910579c5a1042a1d74e13c09cd0a46">broken()</a> method is provided, which causes all current waiters to stop waiting, with an exceptional future returned. This allows causing all fibers that are blocked on a condition variable to continue. This issimilar to POSIX's <code>pthread_cancel()</code>, with <a class="el" href="classseastar_1_1condition__variable.html#a472036511ce19186d8b9a6b253b83271">wait()</a> acting as a cancellation point. </p>

+class seastar::coroutine::all&lt; Futures &gt;</div><p >Wait for serveral futures to complete in a coroutine.</p>
+<p ><code>all</code> can be used to launch several computations concurrently and wait for all of them to complete. Computations are provided as callable objects (typically lambda coroutines) that are invoked by <code>all</code>. Waiting is performend by <code>co_await</code> and returns a tuple of values, one for each non-void future.</p>
+<p >If one or more of the function objects throws an exception, or if one or more of the futures resolves to an exception, then the exception is thrown. All of the futures are waited for, even in the case of exceptions. If more than one exception is present, an arbitrary one is thrown.</p>

+<p >A <code>deleter</code> is an object that is used to inform the consumer of some buffer (not referenced by the deleter itself) how to delete the buffer. This can be by calling an arbitrary function or destroying an object carried by the deleter. Examples of a deleter's encapsulated actions are:</p>
+<ul>
+<li>calling <code>std::free(p)</code> on some captured pointer, p</li>
+<li>calling <code>delete</code> <code>p</code> on some captured pointer, p</li>
+<li>decrementing a reference count somewhere</li>

+<p >This is a thin wrapper around inotify(see <a href="http://man7.org/linux/man-pages/man7/inotify.7.html">http://man7.org/linux/man-pages/man7/inotify.7.html</a>), which is the de-facto light-weight filesystem modification watch interface in Linux and can be used to log filesystem activities, reload configurations, etc.</p>
+<p >The wrapper provides a buffered read of events, and RAII handling of watches themselves.</p>
+<dl class="section note"><dt>Note</dt><dd>Note that this is an experimental feature, and thus any tweaks that are backward incompatible can be made before finally freezing it. Besides, the impl currently does not (yet) handle re-writing watches. </dd></dl>

+<p >This is a fair group. It's attached by one or mode fair queues. On machines having the big* amount of shards, queues use the group to borrow/lend the needed capacity for requests dispatching.</p>
+<ul>
+<li>Big means that when all shards sumbit requests alltogether the disk is unable to dispatch them efficiently. The inability can be of two kinds &ndash; either disk cannot cope with the number of arriving requests, or the total size of the data withing the given time frame exceeds the disk throughput. </li>

+<p >This is a fair queue, allowing multiple request producers to queue requests that will then be served proportionally to their classes' shares.</p>
+<p >To each request, a weight can also be associated. A request of weight 1 will consume 1 share. Higher weights for a request will consume a proportionally higher amount of shares.</p>
+<p >The user of this interface is expected to register multiple <code>priority_class_data</code> objects, which will each have a shares attribute.</p>
+<p >Internally, each priority class may keep a separate queue of requests. Requests pertaining to a class can go through even if they are over its share limit, provided that the other classes have empty queues.</p>
+<p >When the classes that lag behind start seeing requests, the fair queue will serve them first, until balance is restored. This balancing is expected to happen within a certain time window that obeys an exponential decay. </p>

Refer fcntl(2) man page for more details on write lifetime hints.</p>

+class seastar::future&lt; T &gt;</div><p >A representation of a possibly not-yet-computed value. </p>
+<p >A <code>future</code> represents a value that has not yet been computed (an asynchronous computation). It can be in one of several states:</p><ul>
+<li>unavailable: the computation has not been completed yet</li>
+<li>value: the computation has been completed successfully and a value is available.</li>
+<li>failed: the computation completed with an exception.</li>
+</ul>
+<p >methods in <code>future</code> allow querying the state and, most importantly, scheduling a <code>continuation</code> to be executed when the future becomes available. Only one such continuation may be scheduled.</p>
+<p >A <a class="el" href="classseastar_1_1future.html">future</a> should not be discarded before it is waited upon and its result is extracted. Discarding a <a class="el" href="classseastar_1_1future.html">future</a> means that the computed value becomes inaccessible, but more importantly, any exceptions raised from the computation will disappear unchecked as well. Another very important consequence is potentially unbounded resource consumption due to the launcher of the deserted continuation not being able track the amount of in-progress continuations, nor their individual resource consumption. To prevent accidental discarding of futures, <a class="el" href="classseastar_1_1future.html">future</a> is declared <code>[[nodiscard]]</code> if the compiler supports it. Also, when a discarded <a class="el" href="classseastar_1_1future.html">future</a> resolves with an error a warning is logged (at runtime). That said there can be legitimate cases where a <a class="el" href="classseastar_1_1future.html">future</a> is discarded. The most prominent example is launching a new <a class="el" href="group__fiber-module.html">fiber</a>, or in other words, moving a continuation chain to the background (off the current <a class="el" href="group__fiber-module.html">fiber</a>). Even if a <a class="el" href="classseastar_1_1future.html">future</a> is discarded purposefully, it is still strongly advisable to wait on it indirectly (via a <a class="el" href="classseastar_1_1gate.html">gate</a> or <a class="el" href="group__fiber-module.html#ga0f8a4046e6c0b61cde9391144c6f0029">semaphore</a>), control their concurrency, their resource consumption and handle any errors raised from them.</p>

+<dl class="section note"><dt>Note</dt><dd>The <code>get0()</code> method is deprecated. It's a remnant from older versions of Seastar that supported variadic futures, capable of returning multiple values through a tuple. Back then, <code>get0()</code> served the purpose of retrieving the first (and usually the only) value. Today, the <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get()</a> method accomplishes the same task. However, there's a subtle difference in return types: <code>get0()</code> returned <code>T</code>, while <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get()</a> returns <code>T&amp;&amp;</code> (an rvalue reference to <code>T</code>). This distinction typically won't cause issues when switching from <code>get0()</code> to <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get()</a>. However, in specific metaprogramming scenarios, especially when the code expects type <code>T</code>, you'll need to use <code>std::remove_reference_t&lt;decltype(fut.get())&gt;</code> to extract the underlying type <code>T</code>. For new code that utilizes <code>future&lt;tuple&lt;...&gt;&gt;</code>, employ <code>std::get&lt;0&gt;</code>(fut.get()) to access the first element of the tuple, rather than the deprecated get0(). </dd></dl>

+<p>The client uses connections provided by factory to send requests over and receive responses back. Once request-response cycle is over the connection used for that is kept by a client in a "pool". Making another http request may then pick up the existing connection from the pool thus avoiding the extra latency of establishing new connection. Pool may thus accumulate more than one connection if user sends several requests in parallel.</p>
+<p >HTTP servers may sometimes want to terminate the connections it keeps. This can happen in one of several ways.</p>
+<p >The "gentle" way is when server adds the "connection: close" header to its response. In that case client would handle the response and will just close the connection without putting it to pool.</p>
+<p >Less gentle way a server may terminate a connection is by closing it, so the underlying TCP stack would communicate regular TCP FIN-s. If the connection happens to be in pool when it happens the client would just clean the connection from pool in the background.</p>
+<p >Sometimes the least gentle closing occurs when server closes the connection on the fly and TCP starts communicating FIN-s in parallel with client using it. In that case, user would receive exception from the <a class="el" href="classseastar_1_1http_1_1experimental_1_1client.html#a168945e53d5425c03dcda169829ed2b8">make_request()</a> call and will have to do something about it. Client provides a transparent way of handling it called "retry".</p>
+<p >When enabled, it makes client catch the transport error, close the broken connection, open another one and retry the very same request one more time over this new connection. If the second attempt fails, this error is reported back to user. </p>

+<div class="textblock"><p >Base class for layered file implementations.</p>
+<p >A layered file implementation implements <code><a class="el" href="classseastar_1_1file__impl.html">file_impl</a></code> virtual functions such as dma_read() by forwarding them to another, existing file called the underlying file. This base class simplifies construction of layered files by performing standard tasks such as setting up the file alignment. Actual implementation of the I/O methods is left for the derived class. </p>

+class seastar::metrics::internal::approximate_exponential_histogram&lt; Min, Max, Precision &gt;</div><p >This is a pseudo-exponential implementation of an estimated histogram.</p>
+<p >An exponential-histogram with coefficient 'coef', is a histogram where for bucket 'i' the lower limit is coef^i and the higher limit is coef^(i+1).</p>
+<p >A pseudo-exponential is similar but the bucket limits are an approximation.</p>
+<p >The <a class="el" href="classseastar_1_1metrics_1_1internal_1_1approximate__exponential__histogram.html">approximate_exponential_histogram</a> is an efficient pseudo-exponential implementation.</p>
+<p >The histogram is defined by a Min and Max value limits, and a Precision (all should be power of 2 and will be explained).</p>
+<p >When adding a value to a histogram: All values lower than Min will be included in the first bucket (the assumption is that it's not suppose to happen but it is ok if it does).</p>
+<p >All values higher than Max will be included in the last bucket that serves as the infinity bucket (the assumption is that it can happen but it is rare).</p>
+<p >Note the difference between the first and last buckets. The first bucket is just like a regular bucket but has a second roll to collect unexpected low values. The last bucket, also known as the infinity bucket, collect all values that passes the defined Max, it only collect those values.</p>
+<h1><a class="anchor" id="autotoc_md0"></a>
+Buckets Distribution (limits)</h1>
+<p >The buckets limits in the histogram are defined similar to a floating-point representation.</p>
+<p >Buckets limits have an exponent part and a linear part.</p>
+<p >The exponential part is a power of 2. Each power-of-2 range [2^n..2^n+1) is split linearly to 'Precision' number of buckets.</p>
+<p >The total number of buckets is: NUM_BUCKETS = log2(Max/Min)*Precision +1</p>
+<p >For example, if the Min value is 128, the Max is 1024 and the Precision is 4, the number of buckets is 13.</p>
+<p >Anything below 160 will be in the bucket 0, anything above 1024 will be in bucket 13. Note that the first bucket will include all values below Min.</p>
+<p >the range [128, 1024) will be split into log2(1024/128) = 3 ranges: 128, 256, 512, 1024 Or more mathematically: [128, 256), [256, 512), [512,1024)</p>
+<p >Each range is split into 4 (The Precision). 128 | 256 | 512 | 1024 128 160 192 224| 256 320 384 448| 512 640 768 896|</p>
+<p >To get the exponential part of an index you divide by the Precision. The linear part of the index is Modulus the precision.</p>
+<p >Calculating the bucket lower limit of bucket i: The exponential part: exp_part = 2^floor(i/Precision)* Min with the above example 2^floor(i/4)*128 The linear part: (iPrecision) * (exp_part/Precision) With the example: (i%4) * (exp_part/4)</p>
+<p >So the lower limit of bucket 6: 2^floor(6/4)* 128 = 256 (6%4) * 256/4 = 128 lower-limit = 384</p>

+<p >The bucket index consist of two parts: higher bits (exponential part) are based on log2(value/min)</p>
+<p >lower bits (linear part) are based on the 'n' MSB (ignoring the leading 1) where n=log2(Precision). Continuing with the example where the number of precision bits: PRECISION_BITS = log2(4) = 2</p>
+<p >for example: 330 (101001010) The number of precision_bits: PRECISION_BITS = log2(4) = 2 higher bits: log2(330/128) = 1 MSB: 01 (the highest two bits following the leading 1) So the index: 101 = 5</p>
+<h1><a class="anchor" id="autotoc_md2"></a>
+About the Min, Max and Precision</h1>
+<p >For Min, Max and Precision, choose numbers that are a power of 2.</p>
+<p >Limitation: You must set the MIN value to be higher or equal to the Precision.</p>

+class seastar::pipe&lt; T &gt;</div><p >A fixed-size pipe for communicating between two fibers. </p>
+<p >A pipe&lt;T&gt; is a mechanism to transfer data between two fibers, one producing data, and the other consuming it. The fixed-size buffer also ensures a balanced execution of the two fibers, because the producer fiber blocks when it writes to a full pipe, until the consumer fiber gets to run and read from the pipe.</p>
+<p >A pipe&lt;T&gt; resembles a Unix pipe, in that it has a read side, a write side, and a fixed-sized buffer between them, and supports either end to be closed independently (and EOF or broken pipe when using the other side). A pipe&lt;T&gt; object holds the reader and write sides of the pipe as two separate objects. These objects can be moved into two different fibers. Importantly, if one of the pipe ends is destroyed (i.e., the continuations capturing it end), the other end of the pipe will stop blocking, so the other fiber will not hang.</p>
+<p >The pipe's read and write interfaces are future-based blocking. I.e., the write() and read() methods return a future which is fulfilled when the operation is complete. The pipe is single-reader single-writer, meaning that until the future returned by read() is fulfilled, read() must not be called again (and same for write).</p>
+<p >Note: The pipe reader and writer are movable, but <em>not</em> copyable. It is often convenient to wrap each end in a shared pointer, so it can be copied (e.g., used in an std::function which needs to be copyable) or easily captured into multiple continuations. </p>

+<div class="textblock"><p >A group of options.</p>
+<p ><a class="el" href="classseastar_1_1program__options_1_1option__group.html">option_group</a> is the basis for organizing options. It can hold a number of <a class="el" href="classseastar_1_1program__options_1_1basic__value.html">basic_value</a> objects. These are typically also its members: </p><pre class="fragment">struct my_option_group : public option_group {
+    value&lt;&gt; opt1;
+    value&lt;bool&gt; opt2;
+    ...
+
+    my_option_group()
+        : option_group(nullptr, "My option group")
+        , opt1(this, "opt1", ...
+        , opt2(this, "opt2", ...
+        , ...
+    { }
+};
+</pre><p> Option groups can also be nested and using this property one can build a tree of option groups and values. This tree then can be visited using the two visitor methods exposed by option_group:</p><ul>
+<li><a class="el" href="classseastar_1_1program__options_1_1option__group.html#ab5b62e6d6d5df183098344aabc15288b">describe()</a></li>
+<li><a class="el" href="classseastar_1_1program__options_1_1option__group.html#a9436d883e8c98a2e9b852b57155fbc6b">mutate()</a></li>
+</ul>
+<p >Using these two visitors one can easily implement glue code to expose an entire options tree to the command line. Use <a class="el" href="classseastar_1_1program__options_1_1option__group.html#ab5b62e6d6d5df183098344aabc15288b">describe()</a> to build the command-line level description of the objects (using e.g. boost::program_options) and after parsing the provided command-line options use <a class="el" href="classseastar_1_1program__options_1_1option__group.html#a9436d883e8c98a2e9b852b57155fbc6b">mutate()</a> to propagate the extracted values back into the options tree. How this is done is entirely up to the visitors, the above methods only offer an API to visit each group and value in the tree, they don't make any assumption about how the visitor works and what its purpose is. </p>

+class seastar::reference_wrapper&lt; T &gt;</div><p >Wrapper for lvalue references</p>
+<p ><a class="el" href="classseastar_1_1reference__wrapper.html">reference_wrapper</a> wraps a lvalue reference into a copyable and assignable object. It is very similar to std::reference_wrapper except that it doesn't allow implicit construction from a reference and the only way to construct it is to use either <a class="el" href="group__utilities.html#ga5ba6881725ff32611b1842ca528ecc8c" title="Wraps reference in a reference_wrapper.">ref()</a> or <a class="el" href="group__utilities.html#ga69166d6b8f32c3084d3fbd5cd76608a8" title="Wraps constant reference in a reference_wrapper.">cref()</a>. The reason for that discrepancy (and also the reason why <a class="el" href="classseastar_1_1reference__wrapper.html">seastar::reference_wrapper</a> was introduced) is that it serves a different purpose than std::reference_wrapper. The latter protects references from decaying and allows copying and assigning them. <a class="el" href="classseastar_1_1reference__wrapper.html">seastar::reference_wrapper</a> is used mainly to force the user to explicitly state that an object is passed by reference thus reducing the chances of the referred object being prematurely destroyed in case the execution is deferred to a continuation. </p>

+class seastar::rpc::protocol&lt; Serializer, MsgType &gt;</div><p >Defines a protocol for communication between a server and a client.</p>
+<p >A protocol is defined by a <code>Serializer</code> and a <code>MsgType</code>. The <code>Serializer</code> is responsible for serializing and unserializing all types used as arguments and return types used in the protocol. The <code>Serializer</code> is expected to define a <code>read()</code> and <code>write()</code> method for each such type <code>T</code> as follows: </p><pre class="fragment">template &lt;typename Output&gt;
+void write(const serializer&amp;, Output&amp; output, const T&amp; data);
+
+template &lt;typename Input&gt;
+T read(const serializer&amp;, Input&amp; input, type&lt;T&gt; type_tag);  // type_tag used to disambiguate
+</pre><p> Where <code>Input</code> and <code>Output</code> have a <code>void read(char*, size_t)</code> and <code>write(const char*, size_t)</code> respectively. <code>MsgType</code> defines the type to be used as the message id, the id which is used to identify different messages used in the protocol. These are also often referred to as "verbs". The client will use the message id, to specify the remote method (verb) to invoke on the server. The server uses the message id to dispatch the incoming call to the right handler. <code>MsgType</code> should be hashable and serializable. It is preferable to use enum for message types, but do not forget to provide hash function for it.</p>

+Isolation</h2>
+<p >RPC supports isolating verb handlers from each other. There are two ways to achieve this: per-handler isolation (the old way) and per-connection isolation (the new way). If no isolation is configured, all handlers will be executed in the context of the <a class="el" href="classseastar_1_1scheduling__group.html" title="Identifies function calls that are accounted as a group.">scheduling_group</a> in which the <a class="el" href="classseastar_1_1rpc_1_1protocol_1_1server.html" title="Represents the listening port and all accepted connections.">protocol::server</a> was created.</p>
+<p >Per-handler isolation (the old way) can be configured by using the <a class="el" href="classseastar_1_1rpc_1_1protocol.html#ae72396a036b321136ffb0b9d85a3ccff">register_handler()</a> overload which takes a <a class="el" href="classseastar_1_1scheduling__group.html" title="Identifies function calls that are accounted as a group.">scheduling_group</a>. When invoked, the body of the handler will be executed from the context of the configured <a class="el" href="classseastar_1_1scheduling__group.html" title="Identifies function calls that are accounted as a group.">scheduling_group</a>.</p>
+<p >Per-connection isolation (the new way) is a more flexible mechanism that requires user application provided logic to determine how connections are isolated. This mechanism has two parts, the server and the client part. The client configures isolation by setting <a class="el" href="group__rpc.html#acd3e23c31cb27aa7af0099e758d6b733">client_options::isolation_cookie</a>. This cookie is an opaque (to the RPC layer) string that is to be interpreted on the server using user application provided logic. The application provides this logic to the server by setting resource_limits::isolate_connection to an appropriate handler function, that interprets the opaque cookie and resolves it to an <a class="el" href="group__rpc.html#structseastar_1_1rpc_1_1isolation__config" title="Specifies resource isolation for a connection.">isolation_config</a>. The <a class="el" href="classseastar_1_1scheduling__group.html" title="Identifies function calls that are accounted as a group.">scheduling_group</a> in the former will be used not just to execute all verb handlers, but also the connection loop itself, hence providing better isolation.</p>
+<p >There a few gotchas related to mixing the two isolation mechanisms. This can happen when the application is updated and one of the client/server is still using the old/new mechanism. In general per-connection isolation overrides the per-handler one. If both are set up, the former will determine the <a class="el" href="classseastar_1_1scheduling__group.html" title="Identifies function calls that are accounted as a group.">scheduling_group</a> context for the handlers. If the client is not configured to send an isolation cookie, the server's resource_limits::isolate_connection will not be invoked and the server will fall back to per-handler isolation if configured. If the client is configured to send an isolation cookie but the server doesn't have a resource_limits::isolate_connection configured, it will use <a class="el" href="group__rpc.html#ga4bcc6887c3b9f6cb6afc5f64b02e0868">default_isolate_connection()</a> to interpret the cookie. Note that this still overrides the per-handler isolation if any is configured. If the server is so old that it doesn't have the per-connection isolation feature at all, it will of course just use the per-handler one, if configured.</p>

This will be marshalled by rpc, so you do not need to have your Serializer serialize/deserialize this tuple type. The serialization format is compatible with the deprecated variadic future support, and is compatible with adding new return types in a backwards compatible way provided new parameters are appended only, and wrapped with <a class="el" href="classseastar_1_1rpc_1_1optional.html">rpc::optional</a>: <code>future&lt;<a class="el" href="classseastar_1_1rpc_1_1tuple.html">rpc::tuple</a>&lt;existing return type list, <a class="el" href="classseastar_1_1rpc_1_1optional.html">rpc::optional</a>&lt;new_return_type&gt;&gt;&gt; (argument list)</code></p>
+<p >You may also use another tuple type, such as std::tuple. In this case, your Serializer type must recognize your tuple type and provide serialization and deserialization for it. </p>

+class seastar::shared_future&lt; T &gt;</div><p >Like <a class="el" href="classseastar_1_1future.html">future</a> except the result can be waited for by many fibers. </p>
+<p >Represents a value which may not yet be ready. A fiber can wait for the value using the <a class="el" href="classseastar_1_1future.html">future</a> obtained by calling <a class="el" href="classseastar_1_1shared__future.html#aaf056ec5cbf64347845513e356742788">get_future()</a> or casting to <a class="el" href="classseastar_1_1future.html">future</a> type. Multiple fibers are allowed to obtain a <a class="el" href="classseastar_1_1future.html">future</a> for the result using the same instance of <a class="el" href="classseastar_1_1shared__future.html">shared_future</a>.</p>
+<p >All futures obtained from <a class="el" href="classseastar_1_1shared__future.html" title="Like future except the result can be waited for by many fibers.">shared_future</a> should end up in the same state. However, if the value's copy constructor throws, some of the futures may end up in a failed state with an exception thrown from the copy constructor and end up with a state different than other futures.</p>
+<p >The scope of <a class="el" href="classseastar_1_1shared__future.html" title="Like future except the result can be waited for by many fibers.">shared_future</a> instance doesn't have to include scopes of the futures obtained from that instance. In that sense the returned futures are independent.</p>
+<p ><a class="el" href="classseastar_1_1shared__future.html" title="Like future except the result can be waited for by many fibers.">shared_future</a> can be copied at any time and all copies will resolve with the same value.</p>
+<p ><a class="el" href="classseastar_1_1shared__future.html" title="Like future except the result can be waited for by many fibers.">shared_future</a> can be in a disengaged state when it's default-constructed or moved-from. When it's in such a state we say it's invalid and obtaining futures must not be attempted.</p>
+<p >The types in the parameter pack T must all be copy-constructible.</p>
+<p >When the first type in the parameter pack is <a class="el" href="group__future-module.html">with_clock</a> then it has the effect of changing the clock used for timeouts by this instance. This type is omitted from the parameter of the future&lt;&gt; objects.</p>
+<p >Example:</p>
+<p >future&lt;int&gt; f; <a class="el" href="classseastar_1_1shared__future.html" title="Like future except the result can be waited for by many fibers.">shared_future</a>&lt;with_clock&lt;manual_clock&gt;, int&gt; sf(std::move(f)); future&lt;int&gt; f2 = sf; </p>

+<p >Similar to <code>std::shared_mutex</code>, this class provides protection for a shared resource, with two levels of access protection: shared and exclusive. Shared access allows multiple tasks to access the shared resource concurrently, while exclusive access allows just one task to access the resource at a time.</p>
+<p >Note that many seastar tasks do not require protection at all, since the seastar scheduler is not preemptive; however tasks that do (by waiting on a future) may require explicit locking.</p>

+<div class="textblock"><p >A resource controller for cross-shard calls.</p>
+<p >An <a class="el" href="classseastar_1_1smp__service__group.html">smp_service_group</a> allows you to limit the concurrency of <a class="el" href="classseastar_1_1smp.html#a6b3f6578eb387e64989e54ed435d7598">smp::submit_to()</a> and similar calls. While it's easy to limit the caller's concurrency (for example, by using a semaphore), the concurrency at the remote end can be multiplied by a factor of smp::count-1, which can be large.</p>
+<p >The class is called a service <em>group</em> because it can be used to group similar calls that share resource usage characteristics, need not be isolated from each other, but do need to be isolated from other groups. Calls in a group should not nest; doing so can result in ABA deadlocks.</p>
+<p >Nested <a class="el" href="namespaceseastar_1_1alien.html#a50d89de93339ddb7ff802f5ae6b4ffc3">submit_to()</a> calls must form a directed acyclic graph when considering their smp_service_groups as nodes. For example, if a call using ssg1 then invokes another call using ssg2, the internal call may not call again via either ssg1 or ssg2, or it may form a cycle (and risking an ABBA deadlock). Create a new smp_service_group_instead. </p>

+<p >A <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code> is similar to an <code>std::string</code> or a <code>std::unique_ptr&lt;char[]&gt;</code>, but provides more flexible memory management. A <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code> can own the memory it points to, or it can be shared with another <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code>, or point at a substring of a buffer. It uses a <a class="el" href="classseastar_1_1deleter.html">deleter</a> to manage its memory.</p>
+<p >A <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code> should not be held indefinitely. It can be held while a request is processed, or for a similar duration, but not longer, as it can tie up more memory that its size indicates.</p>
+<p >A buffer can be shared: two <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code> objects will point to the same data, or a subset of it. See the <a class="el" href="classseastar_1_1temporary__buffer.html#a936236db3cfbcf6eb6bd708cc57951b6">temporary_buffer::share()</a> method.</p>
+<p >Unless you created a <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code> yourself, do not modify its contents, as they may be shared with another user that does not expect the data to change.</p>
+<p >Use cases for a <code><a class="el" href="classseastar_1_1temporary__buffer.html">temporary_buffer</a></code> include:</p><ul>
+<li>passing a substring of a tcp packet for the user to consume (zero-copy tcp input)</li>
+<li>passing a refcounted blob held in memory to tcp, ensuring that when the TCP ACK is received, the blob is released (by decrementing its reference count) (zero-copy tcp output)</li>

+<p >Timer callbacks should execute quickly. If more involved computation is required, the timer should launch it as a fiber (or signal an existing fiber to continue execution). Fibers launched from a timer callback are executed under the scheduling group that was current when the timer was created (see <a class="el" href="namespaceseastar.html#a67d1258ebbd7b5a4f9c1488ac6ea96b3" title="Returns the current scheduling group.">current_scheduling_group()</a>), or the scheduling that was given explicitly by the caller when the callback was specified.</p>
+<p >Expiration of a <code>timer&lt;std::chrono::steady_clock&gt;</code> is independent of task_quota, so it has relatively high accuracy, but as a result this is a relatively expensive timer. It is recommended to use <code>timer&lt;<a class="el" href="classseastar_1_1lowres__clock.html" title="Low-resolution and efficient steady clock.">lowres_clock</a>&gt;</code> instead, which has very coarse resolution (~10ms) but is quite efficient.

+<p >Execution stages provide an infrastructure for processing function calls in batches in order to improve instruction cache locality. </p>
+<p >When the application logic becomes more and more complex and the length of the data processing pipeline grows it may happen that the most significant bottleneck are instruction cache misses. The solution for that problem may be processing similar operations in batches so that instruction cache locality is improved at the cost of potentially higher latencies and worse data cache locality.</p>
+<p >Execution stages allow batching calls to the specified function object. Every time <a class="el" href="classseastar_1_1concrete__execution__stage.html#a8ae90f114f11600f892b599d7e4a331c">concrete_execution_stage::operator()()</a> is used the function call is added to the queue and a future is returned. Once the number of queued calls reaches certain threshold the stage is flushed and a task is which would execute these function calls is scheduled. Execution stages are also flushed when the reactor polls for events.</p>
+<p >When calling a function that is wrapped inside execution stage it is important to remember that the actual function call will happen at some later time and it has to be guaranteed the objects passed by lvalue reference are still alive. In order to avoid accidental passing of a temporary object by lvalue reference the interface of execution stages accepts only lvalue references wrapped in <a class="el" href="classseastar_1_1reference__wrapper.html">reference_wrapper</a>. It is safe to pass rvalue references, they are decayed and the objects are moved. See <a class="el" href="classseastar_1_1concrete__execution__stage.html#a8ae90f114f11600f892b599d7e4a331c">concrete_execution_stage::operator()()</a> for more details. </p>

+<p >Fibers of execution. </p>
+<p >Seastar continuations are normally short, but often chained to one another, so that one continuation does a bit of work and then schedules another continuation for later. Such chains can be long, and often even involve loopings - see for example repeat. We call such chains "fibers" of execution.</p>
+<p >These fibers are not threads - each is just a string of continuations - but they share some common requirements with traditional threads. For example, we want to avoid one fiber getting starved while a second fiber continuously runs its continuations one after another. As another example, fibers may want to communicate - e.g., one fiber produces data that a second fiber consumes, and we wish to ensure that both fibers get a chance to run, and that if one stops prematurely, the other doesn't hang forever.</p>
+<p >Consult the following table to see which APIs are useful for fiber tasks:</p>

+<p >Seastar provides a file API to deal with persistent storage. Unlike most file APIs, seastar offers unbuffered file I/O (similar to, and based on, <code>O_DIRECT</code>). Unbuffered I/O means that the application is required to do its own caching, but delivers better performance if this caching is done correctly.</p>
+<p >For random I/O or sequential unbuffered I/O, the <a class="el" href="classseastar_1_1file.html">file</a> class provides a set of methods for reading, writing, discarding, or otherwise manipulating a file. For buffered sequential I/O, see <a class="el" href="namespaceseastar.html#ab42e9db5e576c1fa2875b5f8d8f5d21f">make_file_input_stream()</a> and <a class="el" href="namespaceseastar.html#a10c39658b60b6e650e17301accec5d1a">make_file_output_stream()</a>. </p>

+<div class="contents">
+<p >A future has a stored value. Semantically, the value is a std::optional&lt;std::variant&lt;T, std::exception_ptr&gt;&gt;. The actual type of the value in the implementation is future_state&lt;T&gt;.</p>
+<p >A future without an initial value can be created by first creating a promise and then calling <a class="el" href="group__future-module.html#ga2161021ff06a3deb3673b10d3963fbe5" title="Gets the promise&#39;s associated future.">promise::get_future</a>. The promise also stores a future_state&lt;T&gt; in case <a class="el" href="classseastar_1_1promise.html#a8c9a385f90d5b351fc171583fc3fb425" title="Sets the promises value.">promise::set_value</a> is called before get_future.</p>
+<p >In addition to the future_state&lt;T&gt;, the promise and the future point to each other and the pointers are updated when either is moved.</p>
+<p >If a future is consumed by <a class="el" href="classseastar_1_1future.html#a3864e70c07aa00d54c4be2870b06847f" title="Schedule a block of code to run when the future is ready.">future::then</a> before the future is ready, a continuation is dynamically allocated. The continuation also has a future_state&lt;T&gt;, but unlinke a future it is never moved.</p>
+<p >After a future creates a continuation, the corresponding promise points to the newly allocated continuation. When <a class="el" href="classseastar_1_1promise.html#a8c9a385f90d5b351fc171583fc3fb425" title="Sets the promises value.">promise::set_value</a> is called, the continuation is ready and is scheduled.</p>
+<p >A promise then consists of</p><ul>
+<li>A future_state&lt;T&gt; for use when there is no corresponding future or continuation (_local_state).</li>
+<li>A pointer to a future to allow updates when the promise is moved (_future).</li>
+<li>A pointer to the continuation (_task).</li>
+<li>A pointer to future_state&lt;T&gt; (_state) that can point to<ol type="1">
+<li>The future_state&lt;T&gt; in the promise itself</li>
+<li>The future_state&lt;T&gt; in the future</li>
+</ol>
+<ol type="1">
+<li>The future_state&lt;T&gt; in the continuation</li>
+</ol>
+</li>
+</ul>
+<p >A special case is when a future blocks inside a thread. In that case we still need a continuation, but that continuation doesn't need a future_state&lt;T&gt; since the original future still exists on the stack.</p>
+<p >So the valid states for a promise are:</p>
+<ol type="1">
+<li>A newly created promise. _state points to _local_state and _task and _future are null.</li>
+<li>After get_future is called. _state points to the state in the future, _future points to the future and _task is null.</li>
+<li>The future has been consumed by <a class="el" href="classseastar_1_1future.html#a3864e70c07aa00d54c4be2870b06847f" title="Schedule a block of code to run when the future is ready.">future::then</a>. Now the _state points to the state in the continuation, _future is null and _task points to the continuation.</li>
+<li>A call to <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c" title="gets the value returned by the computation">future::get</a> is blocked in a thread. This is a mix of cases 2 and 3. Like 2, there is a valid future and _future and _state point to the future and its state. Like 3, there is a valid continuation and _task points to it, but that continuation has no state of its own. </li>

+<p >Futures and promises are the basic tools for asynchronous programming in seastar. A future represents a result that may not have been computed yet, for example a buffer that is being read from the disk, or the result of a function that is executed on another cpu. A promise object allows the future to be eventually resolved by assigning it a value. </p>
+<p >Another way to look at futures and promises are as the reader and writer sides, respectively, of a single-item, single use queue. You read from the future, and write to the promise, and the system takes care that it works no matter what the order of operations is.</p>
+<p >The normal way of working with futures is to chain continuations to them. A continuation is a block of code (usually a lamdba) that is called when the future is assigned a value (the future is resolved); the continuation can then access the actual value. </p>

+<p >Seastar provides a simple networking API, backed by two TCP/IP stacks: the POSIX stack, utilizing the kernel's BSD socket APIs, and the native stack, implement fully within seastar and able to drive network cards directly. The native stack supports zero-copy on both transmit and receive, and is implemented using seastar's high performance, lockless sharded design. The network stack can be selected with the <code>--network-stack</code> command-line parameter. </p>

+<p >Infrastructure for configuring a seastar application. </p>
+<p >The program-options infrastructure allows configuring seastar both by C++ code and by command-line and/or config files. This is achieved by providing a set of self-describing and self-validating value types as well as option groups to allow grouping them into arbitrary tree structures. Seastar modules expose statically declared option structs, which derive from <a class="el" href="classseastar_1_1program__options_1_1option__group.html">option_group</a> and contain various concrete <a class="el" href="classseastar_1_1program__options_1_1basic__value.html">basic_value</a> members comprising the required configuration. These structs are self-describing, and self-validating, the name of the option group as well as the list of its <a class="el" href="classseastar_1_1program__options_1_1basic__value.html">basic_value</a> member can be queried run-time. </p>

+<p >Support for exploiting multiple cores on a server. </p>
+<p >Seastar supports multicore servers by using <em>sharding</em>. Each logical core (lcore) runs a separate event loop, with its own memory allocator, TCP/IP stack, and other services. Shards communicate by explicit message passing, rather than using locks and condition variables as with traditional threaded programming.</p>
+<p >Smart pointer wrapper which makes it safe to move across CPUs.</p>
+<p ><code>foreign_ptr&lt;&gt;</code> is a smart pointer wrapper which, unlike <a class="el" href="classseastar_1_1shared__ptr.html">shared_ptr</a> and <a class="el" href="classseastar_1_1lw__shared__ptr.html">lw_shared_ptr</a>, is safe to move to a different core.</p>
+<p >As seastar avoids locking, any but the most trivial objects must be destroyed on the same core they were created on, so that, for example, their destructors can unlink references to the object from various containers. In addition, for performance reasons, the shared pointer types do not use atomic operations to manage their reference counts. As a result they cannot be used on multiple cores in parallel.</p>
+<p ><code>foreign_ptr&lt;&gt;</code> provides a solution to that problem. <code>foreign_ptr&lt;&gt;</code> wraps smart pointers &ndash; <a class="el" href="classseastar_1_1shared__ptr.html">seastar::shared_ptr&lt;&gt;</a>, or similar, and remembers on what core this happened. When the <code>foreign_ptr&lt;&gt;</code> object is destroyed, it sends a message to the original core so that the wrapped object can be safely destroyed.</p>
+<p ><code>foreign_ptr&lt;&gt;</code> is a move-only object; it cannot be copied. </p>

+<p >Seastar threads provide an execution environment where blocking is tolerated; you can issue I/O, and wait for it in the same function, rather then establishing a callback to be called with <a class="el" href="classseastar_1_1future.html#a3864e70c07aa00d54c4be2870b06847f">future&lt;&gt;::then()</a>.</p>
+<p >Seastar threads are not the same as operating system threads:</p><ul>
+<li>seastar threads are cooperative; they are never preempted except at blocking points (see below)</li>
+<li>seastar threads always run on the same core they were launched on</li>
+</ul>
+<p >Like other seastar code, seastar threads may not issue blocking system calls.</p>
+<p >A seastar thread blocking point is any function that returns a <a class="el" href="classseastar_1_1future.html">future</a>. you block by calling <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">future&lt;&gt;::get()</a>; this waits for the future to become available, and in the meanwhile, other seastar threads and seastar non-threaded code may execute.</p>
+<p >Example: </p><div class="fragment"><div class="line"><a class="code hl_class" href="classseastar_1_1thread.html">seastar::thread</a> th([] {</div>
+<div class="line">   <a class="code hl_function" href="namespaceseastar.html#a7c875a6dc5869c1f2d5e975eb34746c6">sleep</a>(5s).<a class="code hl_function" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get</a>();  <span class="comment">// blocking point</span></div>

+<p >Seastar provides timers that can be defined to run a callback at a certain time point in the future; timers are provided for <a class="el" href="classseastar_1_1lowres__clock.html">lowres_clock</a> (10ms resolution, efficient), for std::chrono::steady_clock (accurate but less efficient) and for <a class="el" href="classseastar_1_1manual__clock.html">manual_clock</a> (for testing purposes).</p>
+<p >Timers are optimized for cancellation; that is, adding a timer and cancelling it is very efficient. This means that attaching a timer per object for a timeout that rarely happens is reasonable; one does not have to maintain a single timer and a sorted list for this use case.</p>
+<p >Timer callbacks should be short and execute quickly. If involved processing is required, a timer can launch a continuation. </p>

+</div><!--header-->
+<div class="contents">
+<div class="textblock"><p >As a library, Seastar aims to maintain backwards compatibility in terms of the source (application code should continue to build with newer versions of Seastar) and any binary protocols that Seastar exposes (e.g. rpc).</p>
+<p >Link compatibility is not maintained - you cannot link an application built with one version of Seastar with another version of Seastar.</p>
+<h1><a class="anchor" id="autotoc_md44"></a>
+Language standards</h1>
+<p >Seastar will support the last two standards approved by the ISO C++ committee. For example, after C++20 is released, Seastar supports C++17 and C++20. Similarly, when C++23 is released, Seastar will support C++20 and C++23.</p>
+<p >Some features may only be enabled for newer dialects.</p>
+<h1><a class="anchor" id="autotoc_md45"></a>
+Platforms</h1>
+<p >Seastar supports Linux. There is no known minimum kernel version, but very old kernels might not work. Performance can be significantly better for newer kernels.</p>
+<p >Filesystem implementation quality can have significant effect on file I/O performance. XFS is known to be working, ext4 may work well too. Test your filesystem and kernel versions to be sure.</p>
+<p >Patches for new platforms (e.g, Windows) are welcome.</p>
+<h1><a class="anchor" id="autotoc_md46"></a>
+Compilers</h1>
+<p >Seastar supports GCC and Clang. Ports to other compilers are welcome.</p>
+<p >The last two major releases of a compiler are supported (e.g. GCC 13 and GCC 14). Patches to support older versions are welcome, as long as they don't require onerous compromises.</p>
+<h1><a class="anchor" id="autotoc_md47"></a>
+Deprecation</h1>
+<p >Occasionally, we discover that we took the wrong approach with an API. In these cases we will offer a new API and tag the old API with the [[deprecated]] attribute. The deprecated API will be removed after a transition period (which can vary depending on how central the deprecated API is).</p>
+<h1><a class="anchor" id="autotoc_md48"></a>
+Breaking changes</h1>
+<p >Rarely, we have to make breaking changes. We try to limit those, but sometimes there is no choice.</p>
+<p >To support a transition period for breaking changes, Seastar offers the Seastar_API_LEVEL cmake variable (and corresponding &ndash;api-level configure.py option). An API level selects different versions of the API. For example.</p>
+<ul>
+<li>Seastar_API_LEVEL=1 selects an old version of the server_socket::accept() API that returns a variadic future (which is deprecated)</li>
+<li>Seastar_API_LEVEL=2 selects a new version of the server_socket::accept() API that returns a non-variadic future</li>
+<li>Seastar_API_LEVEL=6 makes futures non-variadic</li>
+<li>Seastar_API_LEVEL=7 unifies CPU scheduling groups and IO priority classes "while at it" file_impl API is forced to accept io_intent argument</li>
+</ul>
+<p >Applications can use an old API_LEVEL during a transition period, fix their code, and move to the new API_LEVEL.</p>
+<p >Old API levels only live for a transition period, so if you are using an API level below the latest, you should upgrade quickly.</p>
+<p >Note the application should not refer to the <code>api_vN</code> sub-namespaces that Seastar defines as part of the API_LEVEL mechanism; these are internal.</p>
+<h1><a class="anchor" id="autotoc_md49"></a>
+Internal namespace</h1>
+<p >Identifiers in the <code>seastar::internal</code> namespace are not subject to source level compatibility and are subject to change or removal without notice. In addition the <code>api_vN</code> sub-namespaces are also internal.</p>
+<h1><a class="anchor" id="autotoc_md50"></a>
+Accidentally exposed internal identifiers</h1>
+<p >Some identifiers predate the internal namespace, and are only exposed accidentally. These can also be removed or changed. Exposed identifiers are documented using doxygen, but not all exposed APIs are documented. In case of doubt, ask on the mailing list.</p>

+<p >API levels are implemented by defining internal sub-namespaces for each API level: <code>seastar::api_v1</code>, <code>seatar::api_v2</code> etc. <code>#ifdef</code>s are used to inline the user-selected API level namespace into the main <code>seastar</code> namespace, making it visible.</p>
+<p >Usually, the old API is implemented in terms of the new API to avoid code duplication.</p>
+<p >Here is an example about the transition from API_LEVEL 1 to 2. The transition from 2 to 3 and similar is analogous.</p>
+<p >Unconditionally:</p><ul>
+<li>the new API is defined in sub-namespace <code>api_v2</code></li>
+</ul>
+<p >If API_LEVEL is 2:</p><ul>
+<li><code>api_v2</code> namespace is inlined into the <code>seastar</code> namespace</li>
+</ul>
+<p >If API_LEVEL is 1:</p><ul>
+<li>the old API is defined in sub-namespace <code>api_v1</code></li>
+<li><code>api_v1</code> is implemented in terms of <code>api_v2</code> to prevent code duplication</li>
+<li><code>api_v1</code> namespace is inlined into the <code>seastar</code> namespace</li>
+</ul>
+<p >After a transition period:</p><ul>
+<li>everthing in <code>api_v1</code> is dropped</li>
+<li><code>api_v2</code> is removed, and its contents is placed in the parent namespace </li>
+</ul>

+Supported features</h2>
+<h3><a class="anchor" id="autotoc_md17"></a>
+Compression</h3>
+<p >feature_number: 0 data : opaque data that is passed to a compressor factory provided by an application. Compressor factory is responsible for negotiation of compression algorithm.</p>
+<p >If compression is negotiated request and response frames are encapsulated in a compressed frame.</p>
+<h3><a class="anchor" id="autotoc_md18"></a>
+Timeout propagation</h3>
+<p >feature_number: 1 data : none</p>
+<p >If timeout propagation is negotiated request frame has additional 8 bytes that hold timeout value for a request in milliseconds. Zero value means that timeout value was not specified. If timeout is specified and server cannot handle the request in specified time frame it my choose to not send the reply back (sending it back will not be an error either).</p>
+<h3><a class="anchor" id="autotoc_md19"></a>
+Connection ID</h3>
+<p >feature_number: 2 uint64_t conenction_id : RPC connection ID</p>
+<p >Server assigns unique connection ID for each connection and sends it to a client using this feature.</p>
+<h3><a class="anchor" id="autotoc_md20"></a>
+Stream parent</h3>
+<p >feature_number: 3 uint64_t connection_id : RPC connection ID representing a parent of the stream</p>
+<p >If this feature is present it means that the connection is not regular RPC connection but stream connection. If parent connection is closed or aborted all streams belonging to it will be closed as well.</p>
+<p >Stream connection is a connection that allows bidirectional flow of bytes which may carry one or more messages in each direction. Stream connection should be explicitly closed by both client and server. Closing is done by sending special EOS frame (described below).</p>
+<h3><a class="anchor" id="autotoc_md21"></a>
+Isolation</h3>
+<p >feature number: 4 uint32_t isolation_cookie_len uint8_t isolation_cookie[len]</p>
+<p >The <code>isolation_cookie</code> field is used by the server to select a <code><a class="el" href="classseastar_1_1scheduling__group.html" title="Identifies function calls that are accounted as a group.">seastar::scheduling_group</a></code> (or equivalent in another implementation) that will run this connection. In the future it will also be used for rpc buffer isolation, to avoid rpc traffic in one isolation group from starving another.</p>
+<p >The server does not directly assign meaning to values of <code>isolation_cookie</code>; instead, the interpretation is left to user code.</p>
+<h3><a class="anchor" id="autotoc_md22"></a>
+Handler duration</h3>
+<p >feature number: 5 data: none</p>
+<p >Asks server to send "extended" response that includes the handler duration time. See the response frame description for more details</p>
+<h4><a class="anchor" id="autotoc_md23"></a>
+Compressed frame format</h4>
+<p >uint32_t len uint8_t compressed_data[len]</p>
+<p >After compressed_data is uncompressed, it becomes a regular request, response or streaming frame.</p>
+<p >As a special case, it is allowed to send a compressed frame of size 0 (pre-compression). Such a frame will be a no-op on the receiver. (This can be used as a means of communication between the compressors themselves. If a compressor wants to send some metadata to its peer, it can send a no-op frame, and prepend the metadata as a compressor-specific header.)</p>

+Compression algorithm negotiation</h1>
+<p >RPC protocol only defines <code>COMPRESS</code> feature bit but does not define format of its data. If application supports multiple compression algorithms it may use the data for algorithm negotiation. RPC provides convenience class <code>multi_algo_compressor_factory</code> to do it so that each application will not have to re-implement the same logic. The class gets list of supported compression algorithms and send them as comma separated list in the client <code>COMPRESS</code> feature payload. On receiving of the list it matches common algorithm between client and server. In case there is more than one the order of algorithms in client's list is considered to be a tie breaker (first algorithm wins). Once a compressor is chosen by the server, it puts the identifier of this in the returned <code>COMPRESS</code> feature payload, informing the client of which algorithm should be used for the connection.</p>
+<h1><a class="anchor" id="autotoc_md41"></a>
+Compression algorithms</h1>
+<h2><a class="anchor" id="autotoc_md42"></a>
+&lt;tt&gt;LZ4&lt;/tt&gt; compressor</h2>
+<p >This compressor uses LZ4 to compress and decompress RPC messages. It requires all memory buffers to be contiguous, which may force it to temporarily linearise fragmented messages. LZ4 is fast enough to often make the cost of those copies not negligible compared to the cost of the whole compression or decompression routine. Therefore, this algorithm is best suited if there is an upper bound of the message size and they are expected to fit in a single fragment of input and output memory buffers.</p>
+<h2><a class="anchor" id="autotoc_md43"></a>
+&lt;tt&gt;LZ4_FRAGMENTED&lt;/tt&gt; compressor</h2>
+<p >This compressor uses LZ4 streaming interface to compress and decompress even large messages without linearising them. The LZ4 streaming routines tend to be slower than the basic ones and the general logic for handling buffers is more complex, so this compressor is best suited only when there is no clear upper bound on the message size or if the messages are expected to be fragmented.</p>
+<p >Internally, the compressor processes data in a 32 kB chunks and tries to avoid unnecessary copies as much as possible. It is therefore, recommended, that the application uses memory buffer fragment sizes that are an integral multiple of 32 kB. </p>

+Sink and Source</h2>
+<p >Basic element of streaming API is <code>rpc::sink</code> and <code>rpc::source</code>. The former is used to send data and the later is to receive it. Client and server has their own pair of sink and source. <code>rpc::sink</code> and <code>rpc::source</code> are templated classes where template parameters describe a type of the data that is sent/received. For instance the sink that is used to send messages containing <code>int</code> and <code>long</code> will be of a type <code>rpc::sink&lt;int, long&gt;</code>. The opposite end of the stream will have a source of the type <code>rpc::source&lt;int, long&gt;</code> which will be used to receive those messages. Messages are received at a source as <code>std::optional</code> containing an actual message as an <code>std::tuple</code>. Unengaged optional means EOS (end of stream) - the stream was closed by a peer. If error happen before EOS is received a receiver cannot be sure it received all the data.</p>
+<p >To send the data using <code>rpc::source&lt;int, long&gt;</code> one can write (assuming <code><a class="el" href="group__thread-module.html#ga32db5877f0b27b7afe8b86e81951e28d">seastar::async</a></code> context):</p>

+Creating a stream</h2>
+<p >To open an RPC stream one needs RPC client to be created already. The stream will be associated with the client and will be aborted if the client is closed before streaming is. Given RPC client <code>rc</code>, and a <code>serializer</code> class that models the Serializer concept (as explained in the rpc::protocol class), one creates <code>rpc::sink</code> as follows (again assuming <code><a class="el" href="group__thread-module.html#ga32db5877f0b27b7afe8b86e81951e28d">seastar::async</a></code> context):</p>
+<div class="fragment"><div class="line">rpc::sink&lt;int, long&gt; sink = rc.make_stream_sink&lt;serializer, int, <span class="keywordtype">long</span>&gt;().get();</div>
+</div><!-- fragment --><p >Now the client has the sink that can be used for streaming data to a server, but how the server will get a corresponding <code>rpc::source</code> to read it? For that the sink should be passed to the server by an RPC call. To receive a sink a server should register an RPC handler that will be used to receive it along with any auxiliary information deemed necessary. To receive the sink above one may register an RPC handler like that:</p>
+<div class="fragment"><div class="line">rpc_proto.register_handler(1, [] (<span class="keywordtype">int</span> aux_data, rpc::source&lt;int, long&gt; source) {</div>
+<div class="line">});</div>
+</div><!-- fragment --><p >Notice that <code>rpc::sink</code> is received as an <code>rpc::source</code> since at the server side it will be used for receive. Now all is left to do is for the client to invoke this RPC handler with aux_data and the sink.</p>
+<p >But what about communicating in another direction: from a server to a client. For that a server also has to have a sink and a client has to have a source and since messages in this direction may be of a different type than from client to server the sink and the source may be of a different type as well.</p>
+<p >Server initiates creation of a communication channel in another direction. It does this by creating a sink from the source it receives and returning the sink from RPC handler which will cause it to be received as a source by a client. Lets look at the full example where server want to send message containing sstring to a client.</p>
+<p >Server handler will look like that:</p>
+<div class="fragment"><div class="line">rpc_proto.register_handler(1, [] (<span class="keywordtype">int</span> aux_data, rpc::source&lt;int, long&gt; source) {</div>
+<div class="line">    rpc::sink&lt;sstring&gt; sink = source.make_sink&lt;serializer, sstring&gt;();</div>
+<div class="line">    <span class="comment">// use sink and source asynchronously</span></div>
+<div class="line">    <span class="keywordflow">return</span> sink;</div>
+<div class="line">});</div>
+</div><!-- fragment --><p >Client code will be:</p>
+<div class="fragment"><div class="line"><span class="keyword">auto</span> rpc_call = rpc_proto.make_client&lt;rpc::source&lt;sstring&gt; (<span class="keywordtype">int</span>, rpc::sink&lt;int&gt;)&gt;(1);</div>
+<div class="line">rpc::sink&lt;int, long&gt; sink = rc.make_stream_sink&lt;serializer, int, <span class="keywordtype">long</span>&gt;().get();</div>
+<div class="line">rpc::source&lt;sstring&gt; source = rpc_call(rc, aux_data, sink).get();</div>
+<div class="line"><span class="comment">// use sink and source here</span></div>

+Implementation notes</h1>
+<h2><a class="anchor" id="autotoc_md37"></a>
+RPC stream creation</h2>
+<p >RPC stream is implemented as a separate TCP connection. RPC server knows that a connection will be used for streaming if during RPC negotiation <code>Stream parent</code> feature is present. The feature will contain ID of an RPC client that was used to create the stream.</p>
+<p >So in the example from previous chapter:</p>
+<div class="fragment"><div class="line">rpc::sink&lt;int, long&gt; sink = rc.make_stream_sink&lt;serializer, int, <span class="keywordtype">long</span>&gt;().get();</div>
+</div><!-- fragment --><p >the call will initiate a new TCP connection to the same server <code>rc</code> is connected to. During RPC protocol negotiation this connection will have <code>Stream parent</code> feature with <code>rc</code>'s ID as a value.</p>
+<h2><a class="anchor" id="autotoc_md38"></a>
+Passing sink/source over RPC call</h2>
+<p >When <code>rpc::sink</code> is sent over RPC call it is serialized as its connection ID. Server's RPC handler then lookups the connection and creates an <code>rpc::source</code> from it. When RPC handler returns <code>rpc::sink</code> the same happens in other direction. </p>

+<p >The <code>memory</code> namespace provides functions and classes for interfacing with the seastar memory allocator.</p>
+<p >The seastar memory allocator splits system memory into a pool per logical core (lcore). Memory allocated one an lcore should be freed on the same lcore; failing to do so carries a severe performance penalty. It is possible to share memory with another core, but this should be limited to avoid cache coherency traffic. You can obtain the memory layout of the current shard with get_memory_layout().</p>

+<h3><a class="anchor" id="autotoc_md6"></a>
+Large allocation warning</h3>
+<p >Large allocations put great pressure on the allocator which might be unable to serve them even if there is enough memory available, due to memory fragmentation. This is especially relevant for long-running applications, the kind of applications that are typically built with seastar. This feature allows finding these large by logging a warning on large allocations, with the stacktrace of the. See:</p><ul>
+<li><a class="el" href="namespaceseastar_1_1memory.html#a0f42296c2fe94f53fbdca0d62dd07679">set_large_allocation_warning_threshold()</a></li>

+<h3><a class="anchor" id="autotoc_md7"></a>
+Heap profiling</h3>
+<p >Heap profiling allows finding out how memory is used by your application, by recording the stacktrace of a sampled subset (or all) allocations. See:</p><ul>

+<h3><a class="anchor" id="autotoc_md8"></a>
+Abort on allocation failure</h3>
+<p >Often, the best way to debug an allocation failure is a coredump. This feature allows dumping core on allocation failures, containing the stack of the failed allocation, by means of aborting. To enable this behavior, set <code>abort_on_seastar_bad_alloc</code> in <code><a class="el" href="structseastar_1_1reactor__options.html" title="Configuration for the reactor.">reactor_options</a></code> or pass the <code>--abort-on-seastar-bad-alloc</code> command line flag. Additionally, applications may enable or disable this functionality globally at runtime by calling <code><a class="el" href="namespaceseastar_1_1memory.html#a6612139edb36977f770061377a95a371" title="Set the global state of the abort on allocation failure behavior.">set_abort_on_allocation_failure()</a></code>.</p>
+<h3><a class="anchor" id="autotoc_md9"></a>
+Dump diagnostics report</h3>
+<p >Dump a diagnostic report of the state of the seastar allocator upon allocation failure. The report is dumped with the <code>seastar_memory</code> logger, with debug level. You can configure a report to be dumped with error level on certain allocation kinds, see:</p><ul>
+<li><a class="el" href="namespaceseastar_1_1memory.html#a52e889cff8bbeaecb5231a923e3716c7" title="Configure when memory diagnostics are dumped.">set_dump_memory_diagnostics_on_alloc_failure_kind()</a></li>

+<p>Perform relabeling and operation on metrics dynamically. </p>
+<p >The function would return true if the changes were applied with no conflict or false, if there was a conflict in the registration.</p>
+<p >The general logic follows Prometheus metrics_relabel_config configuration. The relabel rules are applied one after the other. You can add or change a label. you can enable or disable a metric, in that case the metrics will not be reported at all. You can turn on and off the skip_when_empty flag.</p>
+<p >Using the Prometheus convention, the metric name is <b>name</b>. Names cannot be changed.</p>
+<p >Import notes:</p><ul>
+<li>The relabeling always starts from the original set of labels the metric was created with.</li>
+<li>calling with an empty set will remove the relabel config and will return all metrics to their original labels</li>
+<li>To prevent a situation that calling this function would crash the system. in a situation where a conflicting metrics name are entered, an additional label will be added to the labels with a unique ID.</li>
+</ul>
+<p >A few examples: To add a level label with a value 1, to the reactor_utilization metric: std::vector&lt;sm::relabel_config&gt; rl(1); rl[0].source_labels = {"__name__"}; rl[0].target_label = "level"; rl[0].replacement = "1"; rl[0].expr = "reactor_utilization"; set_relabel_configs(rl);</p>
+<p >To report only the metrics with the level label equals 1</p>
+<p >std::vector&lt;sm::relabel_config&gt; rl(2); rl[0].source_labels = {"__name__"}; rl[0].action = sm::relabel_config::relabel_action::drop;</p>
+<p >rl[1].source_labels = {"level"}; rl[1].expr = "1"; rl[1].action = sm::relabel_config::relabel_action::keep; set_relabel_configs(rl); </p>

+<p >Usage is hopefully straight forward. Though, feel free to read <a href="https://collectd.org/wiki/index.php/Naming_schema">https://collectd.org/wiki/index.php/Naming_schema</a> for an explanation on the naming model.</p>
+<p >Typically, you'll add values something like: </p><pre class="fragment">            scollectd::type_instance_id typ("&lt;pluginname&gt;", "&lt;instance_name&gt;", "&lt;type_name&gt;", "&lt;instance_name&gt;");
+    scollectd::add_polled_metric(typ, [&lt;metric var&gt; | scollectd::make_typed(&lt;data_type&gt;, &lt;metric_var&gt;) [, ...]);
+</pre><p> Where <code>&lt;pluginname&gt;</code> would be the overall 'module', e.g. "cpu" <code>&lt;instance_name&gt;</code> -&gt; optional distinguisher between plugin instances. For cpu, the built-in scollectd::per_cpu_plugin_instance constant is a good choice, i.e. 0-&gt;N cpu. If there are no instances (e.g. only one), empty constant is appropriate (none) <code>&lt;type_name&gt;</code> is the 'type' of metric collected, for ex. "usage" (cpu/0/usage) <code>&lt;type_instance&gt;</code> is a distinguisher for metric parts of the type, e.g. "idle", "user", "kernel" -&gt; cpu/0/usage/idle | cpu/0/usage/user | cpu/0/usage/kernel</p>
+<p >Each type instance can bind an arbitrary number of values, ech representing some aspect in turn of the instance. The structure and interpretation is up to the producer/consumer</p>
+<p >There is a single "scollectd" instance per cpu, and values should be bound locally to this cpu. Polling is done at a frequency set in the seastar config (def once per s), and all registered values will be sent via UDP packages to the destination host(s)</p>
+<p >Note that the tuple { plugin, plugin_instance, type, type_instance } is considered a unique ID for a value registration, so using the same tuple twice will remove the previously registered values.</p>
+<p >Values can be unregistered at any time, though they must be so on the same thread/cpu as they we're registered. The "registration" achor type provides RAII style value unregistration semantics. </p>

+<p><strong>Seastar</strong>, which we introduce in this document, is a
+C++ library for writing highly efficient complex server applications on
+modern multi-core machines.</p>
+<p>Traditionally, the programming languages libraries and frameworks
+used for writing server applications have been divided into two distinct
+camps: those focusing on efficiency, and those focusing on complexity.
+Some frameworks are extremely efficient and yet allow building only
+simple applications (e.g., DPDK allows applications which process
+packets individually), while other frameworks allow building extremely
+complex applications, at the cost of run-time efficiency. Seastar is our
+attempt to get the best of both worlds: To create a library which allows
+building highly complex server applications, and yet achieve optimal
+performance.</p>
+<p>The inspiration and first use case of Seastar was Scylla, a rewrite
+of Apache Cassandra. Cassandra is a very complex application, and yet,
+with Seastar we were able to re-implement it with as much as 10-fold
+throughput increase, as well as significantly lower and more consistent
+latencies.</p>
+<p>Seastar offers a complete asynchronous programming framework, which
+uses two concepts - <strong>futures</strong> and
+<strong>continuations</strong> - to uniformly represent, and handle,
+every type of asynchronous event, including network I/O, disk I/O, and
+complex combinations of other events.</p>
+<p>Since modern multi-core and multi-socket machines have steep
+penalties for sharing data between cores (atomic instructions, cache
+line bouncing and memory fences), Seastar programs use the share-nothing
+programming model, i.e., the available memory is divided between the
+cores, each core works on data in its own part of memory, and
+communication between cores happens via explicit message passing (which
+itself happens using the SMP&#8217;s shared memory hardware, of course).</p>
+<h2 data-number="1.1" id="asynchronous-programming"><span class="header-section-number">1.1</span> Asynchronous programming</h2>
+<p>A server for a network protocol, such as the classic HTTP (Web) or
+SMTP (e-mail) servers, inherently deals with parallelism: Multiple
+clients send requests in parallel, and we cannot finish handling one
+request before starting to handle the next: A request may, and often
+does, need to block because of various reasons &#8212; a full TCP window
+(i.e., a slow connection), disk I/O, or even the client holding on to an
+inactive connection &#8212; and the server needs to handle other connections
+as well.</p>
+<p>The most straightforward way to handle such parallel connections,
+employed by classic network servers such as Inetd, Apache Httpd and
+Sendmail, is to use a separate operating-system process per connection.
+This technique evolved over the years to improve its performance: At
+first, a new process was spawned to handle each new connection; Later, a
+pool of existing processes was kept and each new connection was assigned
+to an unemployed process from the pool; Finally, the processes were
+replaced by threads. However, the common idea behind all these
+implementations is that at each moment, each process handles exclusively
+a single connection. Therefore, the server code is free to use blocking
+system calls, such as reading or writing to a connection, or reading
+from disk, and if this process blocks, all is well because we have many
+additional processes ready to handle other connections.</p>
+<p>Programming a server which uses a process (or a thread) per
+connection is known as <em>synchronous</em> programming, because the
+code is written linearly, and one line of code starts to run after the
+previous line finished. For example, the code may read a request from a
+socket, parse the request, and then piecemeal read a file from disk and
+write it back to the socket. Such code is easy to write, almost like
+traditional non-parallel programs. In fact, it&#8217;s even possible to run an
+external non-parallel program to handle each request &#8212; this is for
+example how Apache HTTPd ran &#8220;CGI&#8221; programs, the first implementation of
+dynamic Web-page generation.</p>
+<blockquote>
+<p>NOTE: although the synchronous server application is written in a
+linear, non-parallel, fashion, behind the scenes the kernel helps ensure
+that everything happens in parallel and the machine&#8217;s resources &#8212; CPUs,
+disk and network &#8212; are fully utilized. Beyond the process parallelism
+(we have multiple processes handling multiple connections in parallel),
+the kernel may even parallelize the work of one individual connection &#8212;
+for example process an outstanding disk request (e.g., read from a disk
+file) in parallel with handling the network connection (send
+buffered-but-yet-unsent data, and buffer newly-received data until the
+application is ready to read it).</p>
+</blockquote>
+<p>But synchronous, process-per-connection, server programming didn&#8217;t
+come without disadvantages and costs. Slowly but surely, server authors
+realized that starting a new process is slow, context switching is slow,
+and each process comes with significant overheads &#8212; most notably the
+size of its stack. Server and kernel authors worked hard to mitigate
+these overheads: They switched from processes to threads, from creating
+new threads to thread pools, they lowered default stack size of each
+thread, and increased the virtual memory size to allow more
+partially-utilized stacks. But still, servers with synchronous designs
+had unsatisfactory performance, and scaled badly as the number of
+concurrent connections grew. In 1999, Dan Kegel popularized &#8220;the C10K
+problem&#8221;, the need of a single server to efficiently handle 10,000
+concurrent connections &#8212; most of them slow or even inactive.</p>
+<p>The solution, which became popular in the following decade, was to
+abandon the cozy but inefficient synchronous server design, and switch
+to a new type of server design &#8212; the <em>asynchronous</em>, or
+<em>event-driven</em>, server. An event-driven server has just one
+thread, or more accurately, one thread per CPU. This single thread runs
+a tight loop which, at each iteration, checks, using <code>poll()</code>
+(or the more efficient <code>epoll</code>) for new events on many open
+file descriptors, e.g., sockets. For example, an event can be a socket
+becoming readable (new data has arrived from the remote end) or becoming
+writable (we can send more data on this connection). The application
+handles this event by doing some non-blocking operations, modifying one
+or more of the file descriptors, and maintaining its knowledge of the
+<em>state</em> of this connection.</p>
+<p>However, writers of asynchronous server applications faced, and still
+face today, two significant challenges:</p>
+<ul>
+<li><p><strong>Complexity:</strong> Writing a simple asynchronous server
+is straightforward. But writing a <em>complex</em> asynchronous server
+is notoriously difficult. The handling of a single connection, instead
+of being a simple easy-to-read function call, now involves a large
+number of small callback functions, and a complex state machine to
+remember which function needs to be called when each event
+occurs.</p></li>
+<li><p><strong>Non-blocking:</strong> Having just one thread per core is
+important for the performance of the server application, because context
+switches are slow. However, if we only have one thread per core, the
+event-handling functions must <em>never</em> block, or the core will
+remain idle. But some existing programming languages and frameworks
+leave the server author no choice but to use blocking functions, and
+therefore multiple threads. For example, <code>Cassandra</code> was
+written as an asynchronous server application; But because disk I/O was
+implemented with <code>mmap</code>ed files, which can uncontrollably
+block the whole thread when accessed, they are forced to run multiple
+threads per CPU.</p></li>
+</ul>
+<p>Moreover, when the best possible performance is desired, the server
+application, and its programming framework, has no choice but to also
+take the following into account:</p>
+<ul>
+<li><p><strong>Modern Machines</strong>: Modern machines are very
+different from those of just 10 years ago. They have many cores and deep
+memory hierarchies (from L1 caches to NUMA) which reward certain
+programming practices and penalizes others: Unscalable programming
+practices (such as taking locks) can devastate performance on many
+cores; Shared memory and lock-free synchronization primitives are
+available (i.e., atomic operations and memory-ordering fences) but are
+dramatically slower than operations that involve only data in a single
+core&#8217;s cache, and also prevent the application from scaling to many
+cores.</p></li>
+<li><p><strong>Programming Language:</strong> High-level languages such
+Java, Javascript, and similar &#8220;modern&#8221; languages are convenient, but
+each comes with its own set of assumptions which conflict with the
+requirements listed above. These languages, aiming to be portable, also
+give the programmer less control over the performance of critical code.
+For really optimal performance, we need a programming language which
+gives the programmer full control, zero run-time overheads, and on the
+other hand &#8212; sophisticated compile-time code generation and
+optimization.</p></li>
+</ul>
+<p>Seastar is a framework for writing asynchronous server applications
+which aims to solve all four of the above challenges: It is a framework
+for writing <em>complex</em> asynchronous applications involving both
+network and disk I/O. The framework&#8217;s fast path is entirely
+single-threaded (per core), scalable to many cores and minimizes the use
+of costly sharing of memory between cores. It is a C++14 library, giving
+the user sophisticated compile-time features and full control over
+performance, without run-time overhead.</p>
+<h2 data-number="1.2" id="seastar"><span class="header-section-number">1.2</span> Seastar</h2>
+<p>Seastar is an event-driven framework allowing you to write
+non-blocking, asynchronous code in a relatively straightforward manner
+(once understood). Its APIs are based on futures. Seastar utilizes the
+following concepts to achieve extreme performance:</p>
+<ul>
+<li><strong>Cooperative micro-task scheduler</strong>: instead of
+running threads, each core runs a cooperative task scheduler. Each task
+is typically very lightweight &#8211; only running for as long as it takes to
+process the last I/O operation&#8217;s result and to submit a new one.</li>
+<li><strong>Share-nothing SMP architecture</strong>: each core runs
+independently of other cores in an SMP system. Memory, data structures,
+and CPU time are not shared; instead, inter-core communication uses
+explicit message passing. A Seastar core is often termed a shard. TODO:
+more here https://github.com/scylladb/seastar/wiki/SMP</li>
+<li><strong>Future based APIs</strong>: futures allow you to submit an
+I/O operation and to chain tasks to be executed on completion of the I/O
+operation. It is easy to run multiple I/O operations in parallel - for
+example, in response to a request coming from a TCP connection, you can
+issue multiple disk I/O requests, send messages to other cores on the
+same system, or send requests to other nodes in the cluster, wait for
+some or all of the results to complete, aggregate the results, and send
+a response.</li>
+<li><strong>Share-nothing TCP stack</strong>: while Seastar can use the
+host operating system&#8217;s TCP stack, it also provides its own
+high-performance TCP/IP stack built on top of the task scheduler and the
+share-nothing architecture. The stack provides zero-copy in both
+directions: you can process data directly from the TCP stack&#8217;s buffers,
+and send the contents of your own data structures as part of a message
+without incurring a copy. Read more&#8230;</li>
+<li><strong>DMA-based storage APIs</strong>: as with the networking
+stack, Seastar provides zero-copy storage APIs, allowing you to DMA your
+data to and from your storage devices.</li>
+</ul>
+<p>This tutorial is intended for developers already familiar with the
+C++ language, and will cover how to use Seastar to create a new
+application.</p>

+<p>Seastar continuations are normally short, but often chained to one
+another, so that one continuation does a bit of work and then schedules
+another continuation for later. Such chains can be long, and often even
+involve loopings - see the following section, &#8220;Loops&#8221;. We call such
+chains &#8220;fibers&#8221; of execution.</p>
+<p>These fibers are not threads - each is just a string of continuations
+- but they share some common requirements with traditional threads. For
+example, we want to avoid one fiber getting starved while a second fiber
+continuously runs its continuations one after another. As another
+example, fibers may want to communicate - e.g., one fiber produces data
+that a second fiber consumes, and we wish to ensure that both fibers get
+a chance to run, and that if one stops prematurely, the other doesn&#8217;t
+hang forever.</p>
+<p>TODO: Mention fiber-related sections like loops, semaphores, gates,
+pipes, etc.</p>

+<p>A majority of time-consuming computations involve using loops.
+Seastar provides several primitives for expressing them in a way that
+composes nicely with the future/promise model. A very important aspect
+of Seastar loop primitives is that each iteration is followed by a
+preemption point, thus allowing other tasks to run in between
+iterations.</p>
+<h2 data-number="11.1" id="repeat"><span class="header-section-number">11.1</span> repeat</h2>
+<p>A loop created with <code>repeat</code> executes its body until it
+receives a <code>stop_iteration</code> object, which informs if the
+iteration should continue (<code>stop_iteration::no</code>) or stop
+(<code>stop_iteration::yes</code>). Next iteration will be launched only
+after the first one has finished. The loop body passed to
+<code>repeat</code> is expected to have a
+<code>future&lt;stop_iteration&gt;</code> return type.</p>

+<p>A <code>do_for_each</code> is an equivalent of a <code>for</code>
+loop in Seastar world. It accepts a range (or a pair of iterators) and a
+function body, which it applies to each argument, in order, one by one.
+The next iteration will be launched only after the first one has
+finished, as was the case with <code>repeat</code>. As usual,
+<code>do_for_each</code> expects its loop body to return a
+<code>future&lt;&gt;</code>.</p>

+<p><code>parallel_for_each</code> is a powerful tool, as it allows
+spawning many tasks in parallel. It can be a great performance gain, but
+there are also caveats. First of all, too high concurrency may be
+troublesome - the details can be found in chapter <strong>Limiting
+parallelism of loops</strong>.</p>
+<p>To restrict the concurrency of <code>parallel_for_each</code> by an
+integer number, use <code>max_concurrent_for_each</code> that is
+described below. More details about dealing with parallelism can be
+found in chapter <strong>Limiting parallelism of loops</strong>.</p>
+<p>Secondly, take note that the order in which iterations will be
+executed within a <code>parallel_for_each</code> loop is arbitrary - if
+a strict ordering is needed, consider using <code>do_for_each</code>
+instead.</p>
+<p>TODO: map_reduce, as a shortcut (?) for parallel_for_each which needs
+to produce some results (e.g., logical_or of boolean results), so we
+don&#8217;t need to create a lw_shared_ptr explicitly (or do_with).</p>
+<p>TODO: See seastar commit &#8220;input_stream: Fix possible infinite
+recursion in consume()&#8221; for an example on why recursion is a possible,
+but bad, replacement for repeat(). See also my comment on
+https://groups.google.com/d/msg/seastar-dev/CUkLVBwva3Y/3DKGw-9aAQAJ on
+why Seastar&#8217;s iteration primitives should be used over tail call
+optimization.</p>
+<h2 data-number="11.5" id="max_concurrent_for_each"><span class="header-section-number">11.5</span> max_concurrent_for_each</h2>
+<p>Max concurrent for each is a variant of
+<code>parallel_for_each</code> with restricted parallelism. It accepts
+an additional parameter - <code>max_concurrent</code> - with which, up
+to <code>max_concurrent</code> iterations are queued simultaneously,
+with no guarantee in which order they finish their operations.</p>

+<p>Determining the maximum concurrency limit is out of the scope of this
+document. It should typically be derived from the actual capabilities of
+the system the software is running on, like the number of parallel
+execution units or I/O channels, so to optimize utilization of resources
+without overwhelming the system.</p>

+<p>The first variant of <code>when_all()</code> is variadic, i.e., the
+futures are given as separate parameters, the exact number of which is
+known at compile time. The individual futures may have different types.

+<p>This starts three futures - one which sleeps for one second (and
+doesn&#8217;t return anything), one which sleeps for two seconds and returns
+the integer 2, and one which returns the double 3.5 immediately - and
+then waits for them. The <code>when_all()</code> function returns a
+future which resolves as soon as all three futures resolves, i.e., after
+two seconds. This future also has a value, which we shall explain below,
+but in this example, we simply waited for the future to resolve and
+discarded its value.</p>
+<p>Note that <code>when_all()</code> accept only rvalues, which can be
+temporaries (like the return value of an asynchronous function or
+<code>make_ready_future</code>) or an <code>std::move()</code>&#8217;ed
+variable holding a future.</p>
+<p>The future returned by <code>when_all()</code> resolves to a tuple of
+futures which are already resolved, and contain the results of the three
+input futures. Continuing the above example,</p>

+<code>1, 2, 3.5</code>: the first future in the tuple is available (but

+<p>One or more of the waited futures might resolve in an exception, but

+<p>Both futures are <code>available()</code> (resolved), but the second
+has <code>failed()</code> (resulted in an exception instead of a value).
+Note how we called <code>ignore_ready_future()</code> on this failed
+future, because silently ignoring a failed future is considered a bug,
+and will result in an &#8220;Exceptional future ignored&#8221; error message. More
+typically, an application will log the failed future instead of ignoring
+it.</p>
+<p>The above example demonstrate that <code>when_all()</code> is
+inconvenient and verbose to use properly. The results are wrapped in a
+tuple, leading to verbose tuple syntax, and uses ready futures which
+must all be inspected individually for an exception to avoid error
+messages.</p>
+<p>So Seastar also provides an easier to use
+<code>when_all_succeed()</code> function. This function too returns a
+future which resolves when all the given futures have resolved. If all
+of them succeeded, it passes a tuple of the resulting values to
+continuation, without wrapping each of them in a future first.
+Sometimes, it could be tedious to unpack the tuple for consuming the
+resulting values. In that case, <code>then_unpack()</code> can be used
+in place of <code>then()</code>. <code>then_unpack()</code> unpacks the
+returned tuple and passes its elements to the following continuation as
+its parameters. If, however, one or more of the futures failed,
+<code>when_all_succeed()</code> resolves to a failed future, containing
+the exception from one of the failed futures. If more than one of the
+given future failed, one of those will be passed on (it is unspecified
+which one is chosen), and the rest will be silently ignored. For
+example,</p>

+<p>Seastar&#8217;s semaphores are the standard computer-science semaphores,
+adapted for futures. A semaphore is a counter into which you can deposit
+units or take them away. Taking units from the counter may wait if not
+enough units are available.</p>
+<h2 data-number="13.1" id="limiting-parallelism-with-semaphores"><span class="header-section-number">13.1</span> Limiting parallelism with
+semaphores</h2>
+<p>The most common use for a semaphore in Seastar is for limiting
+parallelism, i.e., limiting the number of instances of some code which
+can run in parallel. This can be important when each of the parallel
+invocations uses a limited resource (e.g., memory) so letting an
+unlimited number of them run in parallel can exhaust this resource.</p>
+<p>Consider a case where an external source of events (e.g., an incoming
+network request) causes an asynchronous function <code>g()</code> to be
+called. Imagine that we want to limit the number of concurrent
+<code>g()</code> operations to 100. I.e., If g() is started when 100
+other invocations are still ongoing, we want it to delay its real work
+until one of the other invocations has completed. We can do this with a
+semaphore:</p>

+<p>In this example, the semaphore starts with the counter at 100. The
+asynchronous operation <code>slow()</code> is only started when we can
+reduce the counter by one (<code>wait(1)</code>), and when
+<code>slow()</code> is done, either successfully or with exception, the
+counter is increased back by one (<code>signal(1)</code>). This way,
+when 100 operations have already started their work and have not yet
+finished, the 101st operation will wait, until one of the ongoing
+operations finishes and returns a unit to the semaphore. This ensures
+that at each time we have at most 100 concurrent <code>slow()</code>
+operations running in the above code.</p>
+<p>Note how we used a <code>static thread_local</code> semaphore, so
+that all calls to <code>g()</code> from the same shard count towards the
+same limit; As usual, a Seastar application is sharded so this limit is
+separate per shard (CPU thread). This is usually fine, because sharded
+applications consider resources to be separate per shard.</p>
+<p>Luckily, the above code happens to be exception safe:
+<code>limit.wait(1)</code> can throw an exception when it runs out of
+memory (keeping a list of waiters), and in that case the semaphore
+counter is not decreased but the continuations below are not run so it
+is not increased either. <code>limit.wait(1)</code> can also return an
+exceptional future when the semaphore is <em>broken</em> (we&#8217;ll discuss
+this later) but in that case the extra <code>signal()</code> call is
+ignored. Finally, <code>slow()</code> may also throw, or return an
+exceptional future, but the <code>finally()</code> ensures the semaphore
+is still increased.</p>
+<p>However, as the application code becomes more complex, it becomes
+harder to ensure that we never forget to call <code>signal()</code>
+after the operation is done, regardless of which code path or exceptions
+happen. As an example of what might go wrong, consider the following
+<em>buggy</em> code snippet, which differs subtly from the above one,
+and also appears, on first sight, to be correct:</p>

+<span id="cb73-6"><a href="#cb73-6" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>But this version is <strong>not</strong> exception safe: Consider
+what happens if <code>slow()</code> throws an exception before returning
+a future (this is different from <code>slow()</code> returning an
+exceptional future - we discussed this difference in the section about
+exception handling). In this case, we decreased the counter, but the
+<code>finally()</code> will never be reached, and the counter will never
+be increased back. There is a way to fix this code, by replacing the
+call to <code>slow()</code> with
+<code>seastar::futurize_invoke(slow)</code>. But the point we&#8217;re trying
+to make here is not how to fix buggy code, but rather that by using the
+separate <code>semaphore::wait()</code> and
+<code>semaphore::signal()</code> functions, you can very easily get
+things wrong.</p>
+<p>For exception safety, in C++ it is generally not recommended to have
+separate resource acquisition and release functions. Instead, C++ offers
+safer mechanisms for acquiring a resource (in this case semaphore units)
+and later releasing it: lambda functions, and RAII (&#8220;resource
+acquisition is initialization&#8221;):</p>
+<p>The lambda-based solution is a function
+<code>seastar::with_semaphore()</code> which is a shortcut for the code
+in the examples above:</p>

+<p><code>with_semaphore()</code>, like the earlier code snippets, waits
+for the given number of units from the semaphore, then runs the given
+lambda, and when the future returned by the lambda is resolved,
+<code>with_semaphore()</code> returns back the units to the semaphore.
+<code>with_semaphore()</code> returns a future which only resolves after
+all these steps are done.</p>
+<p>The function <code>seastar::get_units()</code> is more general. It
+provides an exception-safe alternative to
+<code>seastar::semaphore</code>&#8217;s separate <code>wait()</code> and
+<code>signal()</code> methods, based on C++&#8217;s RAII philosophy: The
+function returns an opaque units object, which while held, keeps the
+semaphore&#8217;s counter decreased - and as soon as this object is
+destructed, the counter is increased back. With this interface you
+cannot forget to increase the counter, or increase it twice, or increase
+without decreasing: The counter will always be decreased once when the
+units object is created, and if that succeeded, increased when the
+object is destructed. When the units object is moved into a
+continuation, no matter how this continuation ends, when the
+continuation is destructed, the units object is destructed and the units
+are returned to the semaphore&#8217;s counter. The above examples, written
+with <code>get_units()</code>, looks like this:</p>

+<p>Note the somewhat convoluted way that <code>get_units()</code> needs
+to be used: The continuations must be nested because we need the
+<code>units</code> object to be moved to the last continuation. If
+<code>slow()</code> returns a future (and does not throw immediately),
+the <code>finally()</code> continuation captures the <code>units</code>
+object until everything is done, but does not run any code.</p>
+<p>Seastar&#8217;s programmers should generally avoid using the the
+<code>semaphore::wait()</code> and <code>semaphore::signal()</code>
+functions directly, and always prefer either
+<code>with_semaphore()</code> (when applicable) or
+<code>get_units()</code>.</p>
+<h2 data-number="13.2" id="limiting-resource-use"><span class="header-section-number">13.2</span> Limiting resource use</h2>
+<p>Because semaphores support waiting for any number of units, not just
+1, we can use them for more than simple limiting of the <em>number</em>
+of parallel invocation. For example, consider we have an asynchronous
+function <code>using_lots_of_memory(size_t bytes)</code>, which uses
+<code>bytes</code> bytes of memory, and we want to ensure that not more
+than 1 MB of memory is used by all parallel invocations of this function
+&#8212; and that additional calls are delayed until previous calls have
+finished. We can do this with a semaphore:</p>

+<p>Watch out that in the above example, a call to
+<code>using_lots_of_memory(2000000)</code> will return a future that
+never resolves, because the semaphore will never contain enough units to
+satisfy the semaphore wait. <code>using_lots_of_memory()</code> should

+an exception in that case. Seastar doesn&#8217;t do this for you.</p>

+<p>Naively, we could achieve more parallelism, by starting the next call

+<p>Note how this code differs from the code we saw above for limiting
+the number of parallel invocations of a function <code>g()</code>:</p>
+<ol type="1">
+<li>Here we cannot use a single <code>thread_local</code> semaphore.
+Each call to <code>f()</code> has its loop with parallelism of 100, so
+needs its own semaphore &#8220;<code>limit</code>&#8221;, kept alive during the loop
+with <code>do_with()</code>.</li>
+<li>Here we do not wait for <code>slow()</code> to complete before
+continuing the loop, i.e., we do not <code>return</code> the future
+chain starting at <code>futurize_invoke(slow)</code>. The loop continues
+to the next iteration when a semaphore unit becomes available, while (in
+our example) 99 other operations might be ongoing in the background and
+we do not wait for them.</li>
+</ol>
+<p>In the examples in this section, we cannot use the
+<code>with_semaphore()</code> shortcut. <code>with_semaphore()</code>
+returns a future which only resolves after the lambda&#8217;s returned future
+resolves. But in the above example, the loop needs to know when just the
+semaphore units are available, to start the next iteration &#8212; and not
+wait for the previous iteration to complete. We could not achieve that
+with <code>with_semaphore()</code>. But the more general exception-safe
+idiom, <code>seastar::get_units()</code>, can be used in this case, and
+is recommended:</p>

+<p>The above examples are not realistic, because they have a

+the loop we need to wait for all the background operations which the
+loop started. We can do this by <code>wait()</code>ing on the original
+count of the semaphore: When the full count is finally available, it

+<p>The last <code>finally</code> is what ensures that we wait for the
+last operations to complete: After the <code>repeat</code> loop ends
+(whether successfully or prematurely because of an exception in one of
+the iterations), we do a <code>wait(100)</code> to wait for the
+semaphore to reach its original value 100, meaning that all operations
+that we started have completed. Without this <code>finally</code>, the
+future returned by <code>f()</code> will resolve <em>before</em> all the
+iterations of the loop actually completed (the last 100 may still be
+running).</p>
+<p>In the idiom we saw in the above example, the same semaphore is used
+both for limiting the number of background operations, and later to wait
+for all of them to complete. Sometimes, we want several different loops
+to use the same semaphore to limit their <em>total</em> parallelism. In
+that case we must use a separate mechanism for waiting for the
+completion of the background operations started by the loop. The most
+convenient way to wait for ongoing operations is using a gate, which we
+will describe in detail later. A typical example of a loop whose
+parallelism is limited by an external semaphore:</p>

+<p>In this code, we use the external semaphore <code>limit</code> to
+limit the number of concurrent operations, but additionally have a gate
+specific to this loop to help us wait for all ongoing operations to
+complete.</p>
+<p>TODO: also allow <code>get_units()</code> or something similar on a
+gate, and use that instead of the explicit gate.enter/gate.leave.</p>
+<p>TODO: say something about semaphore fairness - if someone is waiting
+for a lot of units and later someone asks for 1 unit, will both wait or
+will the request for 1 unit be satisfied?</p>
+<p>TODO: say something about broken semaphores? (or in later section
+especially about breaking/closing/shutting down/etc?)</p>
+<p>TODO: Have a few paragraphs, or even a section, on additional uses of
+semaphores. One is for mutual exclusion using semaphore(1) - we need to
+explain why although why in Seastar we don&#8217;t have multiple threads
+touching the same data, if code is composed of different continuations
+(i.e., a fiber) it can switch to a different fiber in the middle, so if
+data needs to be protected between two continuations, it needs a mutex.
+Another example is something akin to wait_all: we start with a
+semaphore(0), run a known number N of asynchronous functions with
+finally sem.signal(), and from all this return the future sem.wait(N).
+PERHAPS even have a separate section on mutual exclusion, where we begin
+with semaphore(1) but also mention shared_mutex</p>

+<p>Seastar&#8217;s <code>pipe&lt;T&gt;</code> is a mechanism to transfer data
+between two fibers, one producing data, and the other consuming it. It
+has a fixed-size buffer to ensures a balanced execution of the two
+fibers, because the producer fiber blocks when it writes to a full pipe,
+until the consumer fiber gets to run and read from the pipe.</p>
+<p>A <code>pipe&lt;T&gt;</code> resembles a Unix pipe, in that it has a
+read side, a write side, and a fixed-sized buffer between them, and
+supports either end to be closed independently (and EOF or broken pipe
+when using the other side). A <code>pipe&lt;T&gt;</code> object holds
+the reader and write sides of the pipe as two separate objects. These
+objects can be moved into two different fibers. Importantly, if one of
+the pipe ends is destroyed (i.e., the continuations capturing it end),
+the other end of the pipe will stop blocking, so the other fiber will
+not hang.</p>
+<p>The pipe&#8217;s read and write interfaces are future-based blocking. I.e.,
+the write() and read() methods return a future which is fulfilled when
+the operation is complete. The pipe is single-reader single-writer,
+meaning that until the future returned by read() is fulfilled, read()
+must not be called again (and same for write). Note: The pipe reader and
+writer are movable, but <em>not</em> copyable. It is often convenient to
+wrap each end in a shared pointer, so it can be copied (e.g., used in an
+std::function which needs to be copyable) or easily captured into
+multiple continuations.</p>

+gate</h1>
+<p>Consider an application which has some long operation
+<code>slow()</code>, and many such operations may be started at any
+time. A number of <code>slow()</code> operations may even even be active
+in parallel. Now, you want to shut down this service, but want to make
+sure that before that, all outstanding operations are completed.
+Moreover, you don&#8217;t want to allow new <code>slow()</code> operations to
+start while the shut-down is in progress.</p>
+<p>This is the purpose of a <code>seastar::gate</code>. A gate
+<code>g</code> maintains an internal counter of operations in progress.
+We call <code>g.enter()</code> when entering an operation (i.e., before
+running <code>slow()</code>), and call <code>g.leave()</code> when
+leaving the operation (when a call to <code>slow()</code> completed).
+The method <code>g.close()</code> <em>closes the gate</em>, which means
+it forbids any further calls to <code>g.enter()</code> (such attempts
+will generate an exception); Moreover <code>g.close()</code> returns a
+future which resolves when all the existing operations have completed.
+In other words, when <code>g.close()</code> resolves, we know that no
+more invocations of <code>slow()</code> can be in progress - because the
+ones that already started have completed, and new ones could not have
+started.</p>

+<p>In this example, we have a function
+<code>future&lt;&gt; slow()</code> taking 10 seconds to complete. We run
+it in a loop 5 times, waiting 1 second between calls, and surround each
+call with entering and leaving the gate (using <code>with_gate</code>).
+After the 5th call, while all calls are still ongoing (because each
+takes 10 seconds to complete), we close the gate and wait for it before
+exiting the program. We also test that new calls cannot begin after
+closing the gate, by trying to enter the gate again one second after
+closing it.</p>
+<p>The output of this program looks like this:</p>
+<pre><code>starting 1
+starting 2
+starting 3
+starting 4
+starting 5
+WARNING: exceptional future ignored of type 'seastar::gate_closed_exception': gate closed
+done 1
+done 2
+done 3
+done 4
+done 5</code></pre>
+<p>Here, the invocations of <code>slow()</code> were started at 1 second
+intervals. After the &#8220;<code>starting 5</code>&#8221; message, we closed the
+gate and another attempt to use it resulted in a
+<code>seastar::gate_closed_exception</code>, which we ignored and hence
+this message. At this point the application waits for the future
+returned by <code>g.close()</code>. This will happen once all the
+<code>slow()</code> invocations have completed: Immediately after
+printing &#8220;<code>done 5</code>&#8221;, the test program stops.</p>
+<p>As explained so far, a gate can prevent new invocations of an
+operation, and wait for any in-progress operations to complete. However,
+these in-progress operations may take a very long time to complete.
+Often, a long operation would like to know that a shut-down has been
+requested, so it could stop its work prematurely. An operation can check
+whether its gate was closed by calling the gate&#8217;s <code>check()</code>
+method: If the gate is already closed, the <code>check()</code> method
+throws an exception (the same
+<code>seastar::gate_closed_exception</code> that <code>enter()</code>
+would throw at that point). The intent is that the exception will cause
+the operation calling it to stop at this point.</p>
+<p>In the previous example code, we had an un-interruptible operation
+<code>slow()</code> which slept for 10 seconds. Let&#8217;s replace it by a
+loop of 10 one-second sleeps, calling <code>g.check()</code> each
+second:</p>

+<p>Now, just one second after gate is closed (after the &#8220;starting 5&#8221;
+message is printed), all the <code>slow()</code> operations notice the
+gate was closed, and stop. As expected, the exception stops the
+<code>do_for_each()</code> loop, and the <code>finally()</code>
+continuation is performed so we see the &#8220;done&#8221; messages for all five
+operations.</p>

+stack</h1>
+<p>TODO: Mention the two modes of operation: Posix and native (i.e.,
+take a L2 (Ethernet) interface (vhost or dpdk) and on top of it we built
+(in Seastar itself) an L3 interface (TCP/IP)).</p>
+<p>For optimal performance, Seastar&#8217;s network stack is sharded just like
+Seastar applications are: each shard (thread) takes responsibility for a
+different subset of the connections. Each incoming connection is
+directed to one of the threads, and after a connection is established,
+it continues to be handled on the same thread.</p>
+<p>In the examples we saw earlier, <code>main()</code> ran our function
+<code>f()</code> only once, on the first thread. Unless the server is
+run with the <code>"-c1"</code> option (one thread only), this will mean
+that any connection arriving to a different thread will not be handled.
+So in all the examples below, we will need to run the same service loop
+on all cores. We can easily do this with the <code>smp::submit_to</code>
+function:</p>

+<p>Here we ask each of Seastar cores (from 0 to
+<code>smp::count</code>-1) to run the same function
+<code>service_loop()</code>. Each of these invocations returns a future,
+and <code>f()</code> will return when all of them have returned (in the
+examples below, they will never return - we will discuss shutting down
+services in later sections).</p>
+<p>We begin with a simple example of a TCP network server written in
+Seastar. This server repeatedly accepts connections on TCP port 1234,
+and returns an empty response:</p>

+<p>This code works as follows:</p>
+<ol type="1">
+<li>The <code>listen()</code> call creates a <code>server_socket</code>
+object, <code>listener</code>, which listens on TCP port 1234 (on any
+network interface).</li>
+<li>We use <code>do_with()</code> to ensure that the listener socket
+lives throughout the loop.</li>
+<li>To handle one connection, we call <code>listener</code>&#8217;s
+<code>accept()</code> method. This method returns a
+<code>future&lt;accept_result&gt;</code>, i.e., is eventually resolved
+with an incoming TCP connection from a client
+(<code>accept_result.connection</code>) and the client&#8217;s IP address and
+port (<code>accept_result.remote_address</code>).</li>
+<li>To repeatedly accept new connections, we use the
+<code>keep_doing()</code> loop idiom. <code>keep_doing()</code> runs its
+lambda parameter over and over, starting the next iteration as soon as
+the future returned by the previous iteration completes. The iterations
+only stop if an exception is encountered. The future returned by
+<code>keep_doing()</code> itself completes only when the iteration stops
+(i.e., only on exception).</li>
+</ol>
+<p>Output from this server looks like the following example:</p>
+<pre><code>$ ./a.out
+Accepted connection from 127.0.0.1:47578
+Accepted connection from 127.0.0.1:47582
+...</code></pre>
+<p>If you run the above example server immediately after killing the
+previous server, it often fails to start again, complaining that:</p>
+<pre><code>$ ./a.out
+program failed with uncaught exception: bind: Address already in use</code></pre>
+<p>This happens because by default, Seastar refuses to reuse the local
+port if there are any vestiges of old connections using that port. In
+our silly server, because the server is the side which first closes the
+connection, each connection lingers for a while in the
+&#8220;<code>TIME_WAIT</code>&#8221; state after being closed, and these prevent
+<code>listen()</code> on the same port from succeeding. Luckily, we can
+give listen an option to work despite these remaining
+<code>TIME_WAIT</code>. This option is analogous to
+<code>socket(7)</code>&#8217;s <code>SO_REUSEADDR</code> option:</p>
+<div class="sourceCode" id="cb92"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb92-1"><a href="#cb92-1" aria-hidden="true" tabindex="-1"></a>    seastar<span class="op">::</span>listen_options lo<span class="op">;</span></span>

+<p>Most servers will always turn on this <code>reuse_address</code>
+listen option. Stevens&#8217; book &#8220;Unix Network Programming&#8221; even says that
+&#8220;All TCP servers should specify this socket option to allow the server
+to be restarted&#8221;. Therefore in the future Seastar should probably
+default to this option being on &#8212; even if for historic reasons this is
+not the default in Linux&#8217;s socket API.</p>
+<p>Let&#8217;s advance our example server by outputting some canned response
+to each connection, instead of closing each connection immediately with
+an empty reply.</p>

+<p>The new part of this code begins by taking the
+<code>connected_socket</code>&#8217;s <code>output()</code>, which returns an
+<code>output_stream&lt;char&gt;</code> object. On this output stream
+<code>out</code> we can write our response using the
+<code>write()</code> method. The simple-looking <code>write()</code>
+operation is in fact a complex asynchronous operation behind the scenes,
+possibly causing multiple packets to be sent, retransmitted, etc., as
+needed. <code>write()</code> returns a future saying when it is ok to
+<code>write()</code> again to this output stream; This does not
+necessarily guarantee that the remote peer received all the data we sent
+it, but it guarantees that the output stream has enough buffer space (or
+in the TCP case, there is enough room in the TCP congestion window) to
+allow another write to begin.</p>
+<p>After <code>write()</code>ing the response to <code>out</code>, the
+example code calls <code>out.close()</code> and waits for the future it
+returns. This is necessary, because <code>write()</code> attempts to
+batch writes so might not have yet written anything to the TCP stack at
+this point, and only when close() concludes can we be sure that all the
+data we wrote to the output stream has actually reached the TCP stack &#8212;
+and only at this point we may finally dispose of the <code>out</code>
+and <code>s</code> objects.</p>
+<p>Indeed, this server returns the expected response:</p>
+<pre><code>$ telnet localhost 1234
+...
+Seastar is the future!
+Connection closed by foreign host.</code></pre>
+<p>In the above example we only saw writing to the socket. Real servers
+will also want to read from the socket. The
+<code>connected_socket</code>&#8217;s <code>input()</code> method returns an
+<code>input_stream&lt;char&gt;</code> object which can be used to read
+from the socket. The simplest way to read from this stream is using the
+<code>read()</code> method which returns a future
+<code>temporary_buffer&lt;char&gt;</code>, containing some more bytes
+read from the socket &#8212; or an empty buffer when the remote end shut down
+the connection.</p>
+<p><code>temporary_buffer&lt;char&gt;</code> is a convenient and safe
+way to pass around byte buffers that are only needed temporarily (e.g.,
+while processing a request). As soon as this object goes out of scope
+(by normal return, or exception), the memory it holds gets automatically
+freed. Ownership of buffer can also be transferred by
+<code>std::move()</code>ing it. We&#8217;ll discuss
+<code>temporary_buffer</code> in more details in a later section.</p>
+<p>Let&#8217;s look at a simple example server involving both reads an writes.
+This is a simple echo server, as described in RFC 862: The server
+listens for connections from the client, and once a connection is
+established, any data received is simply sent back - until the client
+closes the connection.</p>

+<p>The main function <code>service_loop()</code> loops accepting new
+connections, and for each connection calls
+<code>handle_connection()</code> to handle this connection. Our
+<code>handle_connection()</code> returns a future saying when handling
+this connection completed, but importantly, we do
+<strong><em>not</em></strong> wait for this future: Remember that
+<code>keep_doing</code> will only start the next iteration when the
+future returned by the previous iteration is resolved. Because we want
+to allow parallel ongoing connections, we don&#8217;t want the next
+<code>accept()</code> to wait until the previously accepted connection
+was closed. So we call <code>handle_connection()</code> to start the
+handling of the connection, but return nothing from the continuation,
+which resolves that future immediately, so <code>keep_doing</code> will
+continue to the next <code>accept()</code>.</p>
+<p>This demonstrates how easy it is to run parallel <em>fibers</em>
+(chains of continuations) in Seastar - When a continuation runs an
+asynchronous function but ignores the future it returns, the
+asynchronous operation continues in parallel, but never waited for.</p>
+<p>It is often a mistake to silently ignore an exception, so if the
+future we&#8217;re ignoring might resolve with an except, it is recommended to
+handle this case, e.g.&#160;using a <code>handle_exception()</code>
+continuation. In our case, a failed connection is fine (e.g., the client
+might close its connection will we&#8217;re sending it output), so we did not
+bother to handle the exception.</p>
+<p>The <code>handle_connection()</code> function itself is
+straightforward &#8212; it repeatedly calls <code>read()</code> read on the
+input stream, to receive a <code>temporary_buffer</code> with some data,
+and then moves this temporary buffer into a <code>write()</code> call on
+the output stream. The buffer will eventually be freed, automatically,
+when the <code>write()</code> is done with it. When <code>read()</code>
+eventually returns an empty buffer signifying the end of input, we stop
+<code>repeat</code>&#8217;s iteration by returning a
+<code>stop_iteration::yes</code>.</p>

+<p>In the previous section we saw that a Seastar application usually
+needs to run its code on all available CPU cores. We saw that the
+<code>seastar::smp::submit_to()</code> function allows the main
+function, which initially runs only on the first core, to start the
+server&#8217;s code on all <code>seastar::smp::count</code> cores.</p>
+<p>However, usually one needs not just to run code on each core, but
+also to have an object that contains the state of this code.
+Additionally, one may like to interact with those different objects, and
+also have a mechanism to stop the service running on the different
+cores.</p>
+<p>The <code>seastar::sharded&lt;T&gt;</code> template provides a
+structured way create such a <em>sharded service</em>. It creates a
+separate object of type <code>T</code> in each core, and provides
+mechanisms to interact with those copies, to start some code on each,
+and finally to cleanly stop the service.</p>
+<p>To use <code>seastar::sharded</code>, first create a class for the
+object holding the state of the service on a single core. For
+example:</p>

+<p>The <code>s.start()</code> starts the service by creating a
+<code>my_service</code> object on each of the cores. The arguments to
+<code>s.start()</code>, if any (in this example,
+<code>std::string("hello")</code>), are passed to
+<code>my_service</code>&#8217;s constructor.</p>
+<p>But <code>s.start()</code> did not start running any code yet
+(besides the object&#8217;s constructor). For that, we have the
+<code>s.invoke_on_all()</code> which runs the given lambda on all the
+cores - giving each lambda the local <code>my_service</code> object on
+that core. In this example, we have a <code>run()</code> method on each
+object, so we run that.</p>
+<p>Finally, at the end of the run we want to give the service on all
+cores a chance to shut down cleanly, so we call <code>s.stop()</code>.
+This will call the <code>stop()</code> method on each core&#8217;s object, and
+wait for all of them to finish. Calling <code>s.stop()</code> before
+destroying <code>s</code> is mandatory - Seastar will warn you if you
+forget to do it.</p>
+<p>In addition to <code>invoke_on_all()</code> which runs the same code
+on all shards, another feature a sharded service often needs is for one
+shard to invoke code another specific shard. This is done by calling the
+sharded service&#8217;s <code>invoke_on()</code> method. For example:</p>

+<p>As we do in this example, each Seastar program must define and run,
+an <code>app_template</code> object. This object starts the main event
+loop (the Seastar <em>engine</em>) on one or more CPUs, and then runs
+the given function - in this case an unnamed function, a <em>lambda</em>
+- once.</p>
+<p>The <code>return make_ready_future&lt;&gt;();</code> causes the event
+loop, and the whole application, to exit immediately after printing the
+&#8220;Hello World&#8221; message. In a more typical Seastar application, we will
+want event loop to remain alive and process incoming packets (for
+example), until explicitly exited. Such applications will return a
+<em>future</em> which determines when to exit the application. We will
+introduce futures and how to use them below. In any case, the regular C
+<code>exit()</code> should not be used, because it prevents Seastar or
+the application from cleaning up appropriately.</p>
+<p>As shown in this example, all Seastar functions and types live in the
+&#8220;<code>seastar</code>&#8221; namespace. An user can either type this namespace
+prefix every time, or use shortcuts like
+&#8220;<code>using seastar::app_template</code>&#8221; or even
+&#8220;<code>using namespace seastar</code>&#8221; to avoid typing this prefix. We
+generally recommend to use the namespace prefixes <code>seastar</code>
+and <code>std</code> explicitly, and will follow this style in all the
+examples below.</p>
+<p>To compile this program (it&#8217;s present in the
+<code>demos/hello-world.cc</code> file) you can just use Docker.</p>
+<pre><code>$ docker build -t seastar-dev  -f ./docker/dev/Dockerfile .
+$ scripts/build.sh dev
+$ docker run -it --rm -v $(pwd):/seastar seastar-dev /seastar/build/dev/demos/hello-world_demo -c1</code></pre>
+<p>Without the docker help, first make sure you have downloaded, built,
+and optionally installed Seastar, and put the above program in a source
+file anywhere you want, let&#8217;s call the file
+<code>getting-started.cc</code>.</p>
+<p>Linux&#8217;s <a href="http://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</a>
+is one way for easily determining the compilation and linking parameters
+needed for using various libraries - such as Seastar. For example, if
+Seastar was built in the directory <code>$SEASTAR</code> but not
+installed, one can compile <code>getting-started.cc</code> with it using
+the command:</p>
+<pre><code>c++ getting-started.cc `pkg-config --cflags --libs --static $SEASTAR/build/release/seastar.pc`</code></pre>
+<p>The &#8220;<code>--static</code>&#8221; is needed because currently, Seastar is
+built as a static library, so we need to tell <code>pkg-config</code> to
+include its dependencies in the link command (whereas, had Seastar been
+a shared library, it could have pulled in its own dependencies).</p>
+<p>If Seastar <em>was</em> installed, the <code>pkg-config</code>
+command line is even shorter:</p>
+<pre><code>c++ getting-started.cc `pkg-config --cflags --libs --static seastar`</code></pre>
+<p>Alternatively, one can easily build a Seastar program with CMake.
+Given the following <code>CMakeLists.txt</code></p>
+<div class="sourceCode" id="cb5"><pre class="sourceCode cmake"><code class="sourceCode cmake"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="kw">cmake_minimum_required</span> (<span class="ot">VERSION</span> <span class="dt">3.5</span>)</span>

+<p>you can compile the example with the following commands:</p>

+<h2 data-number="21.1" id="standard-seastar-command-line-options"><span class="header-section-number">21.1</span> Standard Seastar command-line
+options</h2>
+<p>All Seastar applications accept a standard set of command-line
+arguments, such as those we&#8217;ve already seen above: The <code>-c</code>
+option for controlling the number of threads used, or <code>-m</code>
+for determining the amount of memory given to the application.</p>
+<p>TODO: list and explain more of these options.</p>
+<p>Every Seastar application also accepts the <code>-h</code> (or
+<code>--help</code>) option, which lists and explains all the available
+options &#8212; the standard Seastar ones, and the user-defined ones as
+explained below.</p>
+<h2 data-number="21.2" id="user-defined-command-line-options"><span class="header-section-number">21.2</span> User-defined command-line
+options</h2>
+<p>Seastar parses the command line options (<code>argv[]</code>) when it
+is passed to <code>app_template::run()</code>, looking for its own
+standard options. Therefore, it is not recommended that the application
+tries to parse <code>argv[]</code> on its own because the application
+might not understand some of the standard Seastar options and not be
+able to correctly skip them.</p>
+<p>Rather, applications which want to have command-line options of their
+own should tell Seastar&#8217;s command line parser of these additional
+application-specific options, and ask Seastar&#8217;s command line parser to
+recognize them too. Seastar&#8217;s command line parser is actually the Boost
+library&#8217;s <code>boost::program_options</code>. An application adds its
+own option by using the <code>add_options()</code> and
+<code>add_positional_options()</code> methods on the
+<code>app_template</code> to define options, and later calling
+<code>configuration()</code> to retrieve the setting of these options.

+<p>In this example, we add via <code>add_options()</code> two
+application-specific options: <code>--flag</code> is an optional
+parameter which doesn&#8217;t take any additional arguments, and
+<code>--size</code> (or <code>-s</code>) takes an integer value, which
+defaults (if this option is missing) to 100. Additionally, we ask via
+<code>add_positional_options()</code> that an unlimited number of
+arguments that do not begin with a &#8220;<code>-</code>&#8221; &#8212; the so-called
+<em>positional</em> arguments &#8212; be collected to a vector of strings
+under the &#8220;filename&#8221; option. Some example outputs from this program:</p>
+<pre><code>$ ./a.out
+Size is 100
+$ ./a.out --flag
+Flag is on
+Size is 100
+$ ./a.out --flag -s 3
+Flag is on
+Size is 3
+$ ./a.out --size 3 hello hi
+Size is 3
+hello
+hi
+$ ./a.out --filename hello --size 3 hi
+Size is 3
+hello
+hi</code></pre>
+<p><code>boost::program_options</code> has more powerful features, such
+as required options, option checking and combining, various option
+types, and more. Please refer to Boost&#8217;s documentation for more
+information.</p>

+<p>If a future resolves with an exception, and the application neglects
+to handle that exception or to explicitly ignore it, the application may
+have missed an important problem. This is likely to be an application
+bug.</p>
+<p>Therefore, Seastar prints a warning message to the log if a future is

+<p>Here, the main function <code>f()</code> calls <code>g()</code>, but
+doesn&#8217;t do anything with the future it returns. But this future resolves
+with an exception, and this exception is silently ignored. So Seastar

+<p>This message says that an exceptional future was ignored, and that
+the type of the exception was &#8220;<code>myexception</code>&#8221;. The type of
+the exception is usually not enough to pinpoint where the problem
+happened, so the warning message also includes the backtrace - the call
+chain - leading to where the exceptional future was destroyed. The
+backtrace is given as a list of addresses, where code in other shared
+libraries is written as a shared library plus offset (when ASLR is
+enabled, the shared libraries are mapped in a different address each
+time).</p>
+<p>Seastar includes a utility, <code>seastar-addr2line</code>, for
+translating these addresses into readable backtraces including exact
+method names, source files and line numbers. This utility needs the
+<em>unstripped</em> executable. Typically, a stripped executable is used
+for production, but an unstripped copy is kept separately to be used in
+debugging - including <code>seastar-addr2line</code>.</p>
+<p>To decode the backtrace, we run</p>
+<pre><code>seastar-addr2line -e a.out</code></pre>
+<p>And then paste the list of addresses in the warning message, and
+conclude with a <code>control-D</code> (it&#8217;s also possible, if you want,
+to put the list of addresses in the <code>seastar-addr2line</code>
+command line). The result looks like this:</p>

+<p>Most of the lines at the bottom of this backtrace are not
+interesting, and just showing the internal details of how Seastar ended
+up running the main function <code>f()</code>. The only interesting part
+is the <em>first</em> few lines:</p>
+<pre><code>seastar::report_failed_future(std::__exception_ptr::exception_ptr const&amp;) at src/core/future.cc:116
+seastar::future_state_base::~future_state_base() at include/seastar/core/future.hh:335

+ (inlined by) seastar::future&lt;&gt;::~future() at include/seastar/core/future.hh:990
+f() at test.cc:12</code></pre>
+<p>Here we see that the warning message was printed by the
+<code>seastar::report_failed_future()</code> function which was called
+when destroying a future (<code>future&lt;&gt;::~future</code>) that had
+not been handled. The future&#8217;s destructor was called in line 11 of our
+test code (<code>26.cc</code>), which is indeed the line where we called
+<code>g()</code> and ignored its result. This backtrace gives us an
+accurate understanding of where our code destroyed an exceptional future
+without handling it first, which is usually helpful in solving these
+kinds of bugs. Note that this technique does not tell us where the
+exception was first created, nor what code passed around the exceptional
+future before it was destroyed - we just learn where the future was
+destroyed. To learn where the exception was originally thrown, see the
+next section:</p>
+<h2 data-number="22.2" id="finding-where-an-exception-was-thrown"><span class="header-section-number">22.2</span> Finding where an exception was
+thrown</h2>
+<p>Sometimes an application logs an exception, and we want to know where
+in the code the exception was originally thrown. Unlike languages like
+Java, C++ does not have a builtin method of attaching a backtrace to
+every exception. So Seastar provides functions which allow adding to an
+exception the backtrace recorded when throwing it.</p>
+<p>For example, in the following code we throw and catch an
+<code>std::runtime_error</code> normally:</p>

+<p>The output is</p>
+<pre><code>Exception: std::runtime_error (hello)</code></pre>
+<p>From this output, we have no way of knowing that the exception was
+thrown in <code>g()</code>. We can solve this if we use
+<code>make_exception_future_with_backtrace</code> instead of
+<code>make_exception_future</code>:</p>
+<pre><code>#include &lt;util/backtrace.hh&gt;
+seastar::future&lt;&gt; g() {
+    return seastar::make_exception_future_with_backtrace&lt;&gt;(std::runtime_error("hello"));
+}</code></pre>
+<p>Now the output looks like</p>
+<pre><code>Exception: seastar::internal::backtraced&lt;std::runtime_error&gt; (hello Backtrace:   0x678bd3
+  0x677204
+  0x67736b
+  0x678cd5
+  0x4f923c
+  0x4f9c38
+  0x4ff4d0
+...
+)</code></pre>
+<p>Which, as above, can be converted to a human-readable backtrace by
+using the <code>seastar-addr2line</code> script.</p>
+<p>In addition to
+<code>seastar::make_exception_future_with_backtrace()</code>, Seastar
+also provides a function <code>throw_with_backtrace()</code>, to throw
+an exception instead of returning an exceptional future. For
+example:</p>
+<pre><code>    seastar::throw_with_backtrace&lt;std::runtime_error&gt;("hello");</code></pre>
+<p>In the current implementation, both
+<code>make_exception_future_with_backtrace</code> and
+<code>throw_with_backtrace</code> require that the original exception
+type (in the above example, <code>std::runtime_error</code>) is a
+subclass of the <code>std::exception</code> class. The original
+exception provides a <code>what()</code> string, and the wrapped
+exception adds the backtrace to this string, as demonstrated above.
+Moreover, the wrapped exception type is a <em>subclass</em> of the
+original exception type, which allows <code>catch(...)</code> code to
+continue filtering by the exception original type - despite the addition
+of the backtrace.</p>

+<p>As we already defined above, An <strong>asynchronous
+function</strong>, also called a <strong>promise</strong>, is a function
+which returns a future and arranges for this future to be eventually
+resolved. As we already saw, an asynchronous function is usually written
+in terms of other asynchronous functions, for example we saw the
+function <code>slow()</code> which waits for the existing asynchronous
+function <code>sleep()</code> to complete, and then returns 3:</p>

+<p>The most basic building block for writing promises is the
+<strong>promise object</strong>, an object of type
+<code>promise&lt;T&gt;</code>. A <code>promise&lt;T&gt;</code> has a
+method <code>future&lt;T&gt; get_future()</code> to returns a future,
+and a method <code>set_value(T)</code>, to resolve this future. An
+asynchronous function can create a promise object, return its future,
+and the <code>set_value</code> method to be eventually called - which
+will finally resolve the future it returned.</p>
+<p>In the following example we create a promise that manages the process
+of printing 10 messages, once every second. We start by creating an
+empty promise to work with. We then spin up a
+<code>seastart::thread</code> to perform the work we want. When the
+work, printing those messages, is completed we call
+<code>promise::set_value</code> to mark the completion of the task.
+Other than that we wait for the future which is generated by our
+promise, just like any other future.</p>

+Seastar</h1>
+<h2 data-number="24.1" id="per-thread-memory-allocation"><span class="header-section-number">24.1</span> Per-thread memory
+allocation</h2>
+<p>Seastar requires that applications be sharded, i.e., that code
+running on different threads operate on different objects in memory. We
+already saw in <a href="3.html#seastar-memory">Seastar memory</a> how Seastar
+takes over a given amount of memory (often, most of the machine&#8217;s
+memory) and divides it equally between the different threads. Modern
+multi-socket machines have non-uniform memory access (NUMA), meaning
+that some parts of memory are closer to some of the cores, and Seastar
+takes this knowledge into account when dividing the memory between
+threads. Currently, the division of memory between threads is static,
+and equal - the threads are expected to experience roughly equal amount
+of load and require roughly equal amounts of memory.</p>
+<p>To achieve this per-thread allocation, Seastar redefines the C
+library functions <code>malloc()</code>, <code>free()</code>, and their
+numerous relatives &#8212; <code>calloc()</code>, <code>realloc()</code>,
+<code>posix_memalign()</code>, <code>memalign()</code>,
+<code>malloc_usable_size()</code>, and <code>malloc_trim()</code>. It
+also redefines the C++ memory allocation functions,
+<code>operator new</code>, <code>operator delete</code>, and all their
+variants (including array versions, the C++14 delete taking a size, and
+the C++17 variants taking required alignment).</p>
+<p>It is important to remember that Seastar&#8217;s different threads
+<em>can</em> see memory allocated by other threads, but they are
+nonetheless strongly discouraged from actually doing this. Sharing data
+objects between threads on modern multi-core machines results in stiff
+performance penalties from locks, memory barriers, and cache-line
+bouncing. Rather, Seastar encourages applications to avoid sharing
+objects between threads when possible (by <em>sharding</em> &#8212; each
+thread owns a subset of the objects), and when threads do need to
+interact they do so with explicit message passing, with
+<code>submit_to()</code>, as we shall see later.</p>
+<h2 data-number="24.2" id="foreign-pointers"><span class="header-section-number">24.2</span> Foreign pointers</h2>
+<p>An object allocated on one thread will be owned by this thread, and
+eventually should be freed by the same thread. Freeing memory on the
+<em>wrong</em> thread is strongly discouraged, but is currently
+supported (albeit slowly) to support library code beyond Seastar&#8217;s
+control. For example, <code>std::exception_ptr</code> allocates memory;
+So if we invoke an asynchronous operation on a remote thread and this
+operation returns an exception, when we free the returned
+<code>std::exception_ptr</code> this will happen on the &#8220;wrong&#8221; core. So
+Seastar allows it, but inefficiently.</p>
+<p>In most cases objects should spend their entire life on a single
+thread and be used only by this thread. But in some cases we want to
+reassign ownership of an object which started its life on one thread, to
+a different thread. This can be done using a
+<code>seastar::foreign_ptr&lt;&gt;</code>. A pointer, or smart pointer,
+to an object is wrapped in a <code>seastar::foreign_ptr&lt;P&gt;</code>.
+This wrapper can then be moved into code running in a different thread
+(e.g., using <code>submit_to()</code>).</p>
+<p>The most common use-case is a
+<code>seastar::foreign_ptr&lt;std::unique_ptr&lt;T&gt;&gt;</code>. The
+thread receiving this <code>foreign_ptr</code> will get exclusive use of
+the object, and when it destroys this wrapper, it will go back to the
+original thread to destroy the object. Note that the object is not only
+freed on the original shard - it is also <em>destroyed</em> (i.e., its
+destructor is run) there. This is often important when the object&#8217;s
+destructor needs to access other state which belongs to the original
+shard - e.g., unlink itself from a container.</p>
+<p>Although <code>foreign_ptr</code> ensures that the object&#8217;s
+<em>destructor</em> automatically runs on the object&#8217;s home thread, it
+does not absolve the user from worrying where to run the object&#8217;s other
+methods. Some simple methods, e.g., methods which just read from the
+object&#8217;s fields, can be run on the receiving thread. However, other
+methods may need to access other data owned by the object&#8217;s home shard,
+or need to prevent concurrent operations. Even if we&#8217;re sure that object
+is now used exclusively by the receiving thread, such methods must still
+be run, explicitly, on the home thread:</p>
+<pre><code>    // fp is some foreign_ptr&lt;&gt;
+    return smp::submit_to(fp.get_owner_shard(), [p=fp.get()]
+        { return p-&gt;some_method(); });</code></pre>
+<p>So <code>seastar::foreign_ptr&lt;&gt;</code> not only has functional
+benefits (namely, to run the destructor on the home shard), it also has
+<em>documentational</em> benefits - it warns the programmer to watch out
+every time the object is used, that this is a <em>foreign</em> pointer,
+and if we want to do anything non-trivial with the pointed object, we
+may need to do it on the home shard.</p>
+<p>Above, we discussed the case of transferring ownership of an object
+to a another shard, via
+<code>seastar::foreign_ptr&lt;std::unique_ptr&lt;T&gt;&gt;</code>.
+However, sometimes the sender does not want to relinquish ownership of
+the object. Sometimes, it wants the remote thread to operate on its
+object and return with the object intact. Sometimes, it wants to send
+the same object to multiple shards. In such cases,
+<code>seastar::foreign_ptr&lt;seastar::lw_shared_ptr&lt;T&gt;&gt;</code>
+is useful. The user needs to watch out, of course, not to operate on the
+same object from multiple threads concurrently. If this cannot be
+ensured by program logic alone, some methods of serialization must be
+used - such as running the operations on the home shard with
+<code>submit_to()</code> as described above.</p>
+<p>Normally, a <code>seastar::foreign_ptr</code> cannot not be copied -
+only moved. However, when it holds a smart pointer that can be copied
+(namely, a <code>shared_ptr</code>), one may want to make an additional
+copy of that pointer and create a second <code>foreign_ptr</code>. Doing
+this is inefficient and asynchronous (it requires communicating with the
+original owner of the object to create the copies), so a method
+<code>future&lt;foreign_ptr&gt; copy()</code> needs to be explicitly
+used instead of the normal copy constructor.</p>

+<p>Seastar&#8217;s programming model, using futures and continuations, is very
+powerful and efficient. However, as we&#8217;ve already seen in examples
+above, it is also relatively verbose: Every time that we need to wait
+before proceeding with a computation, we need to write another
+continuation. We also need to worry about passing the data between the
+different continuations (using techniques like those described in the <a href="8.html#lifetime-management">Lifetime management</a> section). Simple
+flow-control constructs such as loops also become more involved using
+continuations. For example, consider this simple classical synchronous
+code:</p>

+<p>But Seastar also allows, via <code>seastar::thread</code>, to write
+code which looks more like synchronous code. A
+<code>seastar::thread</code> provides an execution environment where
+blocking is tolerated; You can issue an asynchronous function, and wait
+for it in the same function, rather then establishing a callback to be
+called with <code>future&lt;&gt;::then()</code>:</p>

+<p>A <code>seastar::thread</code> is <strong>not</strong> a separate
+operating system thread. It still uses continuations, which are
+scheduled on Seastar&#8217;s single thread (per core). It works as
+follows:</p>
+<p>The <code>seastar::thread</code> allocates a 128KB stack, and runs
+the given function until the it <em>blocks</em> on the call to a
+future&#8217;s <code>get()</code> method. Outside a
+<code>seastar::thread</code> context, <code>get()</code> may only be
+called on a future which is already available. But inside a thread,
+calling <code>get()</code> on a future which is not yet available stops
+running the thread function, and schedules a continuation for this
+future, which continues to run the thread&#8217;s function (on the same saved
+stack) when the future becomes available.</p>
+<p>Just like normal Seastar continuations, <code>seastar::thread</code>s
+always run on the same core they were launched on. They are also
+cooperative: they are never preempted except when
+<code>seastar::future::get()</code> blocks or on explicit calls to
+<code>seastar::thread::yield()</code>.</p>
+<p>It is worth reiterating that a <code>seastar::thread</code> is not a
+POSIX thread, and it can only block on Seastar futures, not on blocking
+system calls. The above example used <code>seastar::sleep()</code>, not
+the <code>sleep()</code> system call. The <code>seastar::thread</code>&#8217;s
+function can throw and catch exceptions normally. Remember that
+<code>get()</code> will throw an exception if the future resolves with
+an exception.</p>
+<p>In addition to <code>seastar::future::get()</code>, we also have
+<code>seastar::future::wait()</code> to wait <em>without</em> fetching
+the future&#8217;s result. This can sometimes be useful when you want to avoid
+throwing an exception when the future failed (as <code>get()</code>
+does). For example:</p>

+<p>While <code>seastar::thread</code>s and <code>seastar::async()</code>
+make programming more convenient, they also add overhead beyond that of
+programming directly with continuations. Most notably, each
+<code>seastar::thread</code> requires additional memory for its stack.
+It is therefore not a good idea to use a <code>seastar::thread</code> to
+handle a highly concurrent operation. For example, if you need to handle
+10,000 concurrent requests, do not use a <code>seastar::thread</code> to
+handle each &#8212; use futures and continuations. But if you are writing code
+where you know that only a few instances will ever run concurrently,
+e.g., a background cleanup operation in your application,
+<code>seastar::thread</code> is a good match.
+<code>seastar::thread</code> is also great for code which doesn&#8217;t care
+about performance &#8212; such as test code.</p>

+components</h1>
+<p>Seastar makes multi-tasking very easy - as easy as running an
+asynchronous function. It is therefore easy for a server to do many
+unrelated things in parallel. For example, a server might be in the
+process of answering 100 users&#8217; requests, and at the same time also be
+making progress on some long background operation.</p>
+<p>But in the above example, what percentage of the CPU and disk
+throughput will the background operation get? How long can one of the
+user&#8217;s requests be delayed by the background operation? Without the
+mechanisms we describe in this section, these questions cannot be
+reliably answered:</p>
+<ul>
+<li>The background operation may be a very &#8220;considerate&#8221; single fiber,
+i.e., run a very short continuation and then schedule the next
+continuation to run later. At each point the scheduler sees 100
+request-handling continuations and just one of the background
+continuations ready to run. The background task gets around 1% of the
+CPU time, and users&#8217; requests are hardly delayed.</li>
+<li>On the other hand, the background operation may spawn 1,000 fibers
+in parallel and have 1,000 ready-to-run continuations at each time. The
+background operation will get about 90% of the runtime, and the
+continuation handling a user&#8217;s request may get stuck behind 1,000 of
+these background continuations, and experience huge latency.</li>
+</ul>
+<p>Complex Seastar applications often have different components which
+run in parallel and have different performance objectives. In the above
+example we saw two components - user requests and the background
+operation. The first goal of the mechanisms we describe in this section
+is to <em>isolate</em> the performance of each component from the
+others; In other words, the throughput and latency of one component
+should not depend on decisions that another component makes - e.g., how
+many continuations it runs in parallel. The second goal is to allow the
+application to <em>control</em> this isolation, e.g., in the above
+example allow the application to explicitly control the amount of CPU
+the background operation receives, so that it completes at a desired
+pace.</p>
+<p>In the above examples we used CPU time as the limited resource that
+the different components need to share effectively. As we show later,
+another important shared resource is disk I/O.</p>

+<p>Consider the following asynchronous function <code>loop()</code>,
+which loops until some shared variable <code>stop</code> becomes true.
+It keeps a <code>counter</code> of the number of iterations until
+stopping, and returns this counter when finally stopping.</p>

+<p>It turns out that if the two <code>loop()</code> calls had the same
+parallelism <code>1</code>, we get roughly the same amount of work from
+both of them:</p>
+<pre><code>Counters: 3'559'635'758, 3'254'521'376</code></pre>
+<p>But if for example we ran a <code>loop(1)</code> in parallel with a
+<code>loop(10)</code>, the result is that the <code>loop(10)</code> gets
+10 times more work done:</p>
+<pre><code>Counters: 629'482'397, 6'320'167'297</code></pre>
+<p>Why does the amount of work that loop(1) can do in ten seconds
+depends on the parallelism chosen by its competitor, and how can we
+solve this?</p>
+<p>The reason this happens is as follows: When a future resolves and a
+continuation was linked to it, this continuation becomes ready to run.
+By default, Seastar&#8217;s scheduler keeps a single list of ready-to-run
+continuations (in each shard, of course), and runs the continuations at
+the same order they became ready to run. In the above example,
+<code>loop(1)</code> always has one ready-to-run continuation, but
+<code>loop(10)</code>, which runs 10 loops in parallel, always has ten
+ready-to-run continuations. So for every continuation of
+<code>loop(1)</code>, Seastar&#8217;s default scheduler will run 10
+continuations of <code>loop(10)</code>, which is why loop(10) gets 10
+times more work done.</p>
+<p>To solve this, Seastar allows an application to define separate
+components known as <strong>scheduling groups</strong>, which each has a
+separate list of ready-to-run continuations. Each scheduling group gets
+to run its own continuations on a desired percentage of the CPU time,
+but the number of runnable continuations in one scheduling group does
+not affect the amount of CPU that another scheduling group gets. Let&#8217;s
+look at how this is done:</p>
+<p>A scheduling group is defined by a value of type
+<code>scheduling_group</code>. This value is opaque, but internally it
+is a small integer (similar to a process ID in Linux). We use the
+<code>seastar::with_scheduling_group()</code> function to run code in
+the desired scheduling group:</p>

+<p>Here we created two scheduling groups, <code>sg1</code> and
+<code>sg2</code>. Each scheduling group has an arbitrary name (which is
+used for diagnostic purposes only), and a number of <em>shares</em>, a
+number traditionally between 1 and 1000: If one scheduling group has
+twice the number of shares than a second scheduling group, it will get
+twice the amount of CPU time. In this example, we used the same number
+of shares (100) for both groups, so they should get equal CPU time.</p>
+<p>Unlike most objects in Seastar which are separate per shard, Seastar
+wants the identities and numbering of the scheduling groups to be the
+same on all shards, because it is important when invoking tasks on
+remote shards. For this reason, the function to create a scheduling
+group, <code>seastar::create_scheduling_group()</code>, is an
+asynchronous function returning a
+<code>future&lt;scheduling_group&gt;</code>.</p>
+<p>Running the above example, with both scheduling group set up with the
+same number of shares (100), indeed results in both scheduling groups
+getting the same amount of CPU time:</p>
+<pre><code>Counters: 3'353'900'256, 3'350'871'461</code></pre>
+<p>Note how now both loops got the same amount of work done - despite
+one loop having 10 times the parallelism of the second loop.</p>
+<p>If we change the definition of the second scheduling group to have
+200 shares, twice the number of shares of the first scheduling group,
+we&#8217;ll see the second scheduling group getting twice the amount of CPU
+time:</p>

+<p>On a machine with 4 hardware threads (two cores, and hyperthreading
+enabled), Seastar will by default start 4 engine threads:</p>
+<pre class="none"><code>$ ./a.out
+4</code></pre>
+<p>Each of these 4 engine threads will be pinned (a la
+<strong>taskset(1)</strong>) to a different hardware thread. Note how,
+as we mentioned above, the app&#8217;s initialization function is run only on
+one thread, so we see the ouput &#8220;4&#8221; only once. Later in the tutorial
+we&#8217;ll see how to make use of all threads.</p>
+<p>The user can pass a command line parameter, <code>-c</code>, to tell
+Seastar to start fewer threads than the available number of hardware
+threads. For example, to start Seastar on only 2 threads, the user can
+do:</p>
+<pre class="none"><code>$ ./a.out -c2
+2</code></pre>
+<p>When the machine is configured as in the example above - two cores
+with two hyperthreads on each - and only two threads are requested,
+Seastar ensures that each thread is pinned to a different core, and we
+don&#8217;t get the two threads competing as hyperthreads of the same core
+(which would, of course, damage performance).</p>
+<p>We cannot start more threads than the number of hardware threads, as
+allowing this will be grossly inefficient. Trying it will result in an
+error:</p>
+<pre class="none"><code>$ ./a.out -c5
+Could not initialize seastar: std::runtime_error (insufficient processing units)</code></pre>
+<p>The error is an exception thrown from app.run, which was caught by
+seastar itself and turned into a non-zero exit code. Note that catching
+the exceptions this way does <strong>not</strong> catch exceptions
+thrown in the application&#8217;s actual asynchronous code. We will discuss
+these later in this tutorial.</p>
+<h2 data-number="3.2" id="seastar-memory"><span class="header-section-number">3.2</span> Seastar memory</h2>
+<p>As explained in the introduction, Seastar applications shard their
+memory. Each thread is preallocated with a large piece of memory (on the
+same NUMA node it is running on), and uses only that memory for its
+allocations (such as <code>malloc()</code> or <code>new</code>).</p>
+<p>By default, the machine&#8217;s <strong>entire memory</strong> except a
+certain reservation left for the OS (defaulting to the maximum of 1.5G
+or 7% of total memory) is pre-allocated for the application in this
+manner. This default can be changed by <em>either</em> changing the
+amount reserved for the OS (not used by Seastar) with the
+<code>--reserve-memory</code> option, or by explicitly giving the amount
+of memory given to the Seastar application, with the <code>-m</code>
+option. This amount of memory can be in bytes, or using the units &#8220;k&#8221;,
+&#8220;M&#8221;, &#8220;G&#8221; or &#8220;T&#8221;. These units use the power-of-two values: &#8220;M&#8221; is a
+<strong>mebibyte</strong>, 2^20 (=1,048,576) bytes, not a
+<strong>megabyte</strong> (10^6 or 1,000,000 bytes).</p>
+<p>Trying to give Seastar more memory than physical memory immediately
+fails:</p>
+<pre class="none"><code>$ ./a.out -m10T
+Couldn't start application: std::runtime_error (insufficient physical memory)</code></pre>

+continuations</h1>
+<p>Futures and continuations, which we will introduce now, are the
+building blocks of asynchronous programming in Seastar. Their strength
+lies in the ease of composing them together into a large, complex,
+asynchronous program, while keeping the code fairly readable and
+understandable.</p>
+<p>A <a href="\ref%20future">future</a> is a result of a computation
+that may not be available yet. Examples include:</p>
+<ul>
+<li>a data buffer that we are reading from the network</li>
+<li>the expiration of a timer</li>
+<li>the completion of a disk write</li>
+<li>the result of a computation that requires the values from one or
+more other futures.</li>
+</ul>
+<p>The type <code>future&lt;int&gt;</code> variable holds an int that
+will eventually be available - at this point might already be available,
+or might not be available yet. The method available() tests if a value
+is already available, and the method get() gets the value. The type
+<code>future&lt;&gt;</code> indicates something which will eventually
+complete, but not return any value.</p>
+<p>A future is usually returned by an <strong>asynchronous
+function</strong>, a function which returns a future and arranges for
+this future to be eventually resolved. Because asynchronous functions
+<em>promise</em> to eventually resolve the future which they returned,
+asynchronous functions are sometimes called &#8220;promises&#8221;; But we will
+avoid this term because it tends to confuse more than it explains.</p>
+<p>One simple example of an asynchronous function is Seastar&#8217;s function
+sleep():</p>
+<div class="sourceCode" id="cb13"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb13-1"><a href="#cb13-1" aria-hidden="true" tabindex="-1"></a>future<span class="op">&lt;&gt;</span> sleep<span class="op">(</span><span class="bu">std::</span>chrono<span class="bu">::</span>duration<span class="op">&lt;</span>Rep<span class="op">,</span> Period<span class="op">&gt;</span> dur<span class="op">);</span></span></code></pre></div>
+<p>This function arranges a timer so that the returned future becomes
+available (without an associated value) when the given time duration
+elapses.</p>
+<p>A <strong>continuation</strong> is a callback (typically a lambda) to
+run when a future becomes available. A continuation is attached to a
+future with the <code>then()</code> method. Here is a simple
+example:</p>

+<span id="cb14-14"><a href="#cb14-14" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>In this example we see us getting a future from
+<code>seastar::sleep(1s)</code>, and attaching to it a continuation
+which prints a &#8220;Done.&#8221; message. The future will become available after 1
+second has passed, at which point the continuation is executed. Running
+this program, we indeed see the message &#8220;Sleeping&#8230;&#8221; immediately, and one
+second later the message &#8220;Done.&#8221; appears and the program exits.</p>
+<p>The return value of <code>then()</code> is itself a future which is
+useful for chaining multiple continuations one after another, as we will
+explain below. But here we just note that we <code>return</code> this
+future from <code>app.run</code>&#8217;s function, so that the program will
+exit only after both the sleep and its continuation are done.</p>
+<p>To avoid repeating the boilerplate &#8220;app_engine&#8221; part in every code
+example in this tutorial, let&#8217;s create a simple main() with which we
+will compile the following examples. This main just calls function
+<code>future&lt;&gt; f()</code>, does the appropriate exception
+handling, and exits when the future returned by <code>f</code> is
+resolved:</p>

+<p>So far, this example was not very interesting - there is no
+parallelism, and the same thing could have been achieved by the normal
+blocking POSIX <code>sleep()</code>. Things become much more interesting
+when we start several sleep() futures in parallel, and attach a
+different continuation to each. Futures and continuation make
+parallelism very easy and natural:</p>

+<p>Each <code>sleep()</code> and <code>then()</code> call returns
+immediately: <code>sleep()</code> just starts the requested timer, and
+<code>then()</code> sets up the function to call when the timer expires.
+So all three lines happen immediately and f returns. Only then, the
+event loop starts to wait for the three outstanding futures to become
+ready, and when each one becomes ready, the continuation attached to it
+is run. The output of the above program is of course:</p>
+<pre class="none"><code>$ ./a.out
+Sleeping... 100ms 200ms Done.</code></pre>
+<p><code>sleep()</code> returns <code>future&lt;&gt;</code>, meaning it
+will complete at a future time, but once complete, does not return any
+value. More interesting futures do specify a value of any type (or
+multiple values) that will become available later. In the following
+example, we have a function returning a <code>future&lt;int&gt;</code>,
+and a continuation to be run once this value becomes available. Note how
+the continuation gets the future&#8217;s value as a parameter:</p>

+<p>The function <code>slow()</code> deserves more explanation. As usual,
+this function returns a <code>future&lt;int&gt;</code> immediately, and
+doesn&#8217;t wait for the sleep to complete, and the code in <code>f()</code>
+can chain a continuation to this future&#8217;s completion. The future
+returned by <code>slow()</code> is itself a chain of futures: It will
+become ready once sleep&#8217;s future becomes ready and then the value 3 is
+returned. We&#8217;ll explain below in more details how <code>then()</code>
+returns a future, and how this allows <em>chaining</em> futures.</p>
+<p>This example begins to show the convenience of the futures
+programming model, which allows the programmer to neatly encapsulate
+complex asynchronous operations. <code>slow()</code> might involve a
+complex asynchronous operation requiring multiple steps, but its user
+can use it just as easily as a simple <code>sleep()</code>, and
+Seastar&#8217;s engine takes care of running the continuations whose futures
+have become ready at the right time.</p>
+<h2 data-number="4.1" id="ready-futures"><span class="header-section-number">4.1</span> Ready futures</h2>
+<p>A future value might already be ready when <code>then()</code> is
+called to chain a continuation to it. This important case is optimized,
+and the continuation is run immediately instead of being registered to
+run later in the next iteration of the event loop.</p>
+<p><code>make_ready_future&lt;&gt;</code> can be used to return a future
+which is already ready. The following example is identical to the
+previous one, except the promise function <code>fast()</code> returns a
+future which is already ready, and not one which will be ready in a
+second as in the previous example. The nice thing is that the consumer
+of the future does not care, and uses the future in the same way in both
+cases.</p>

+<p>As described above, an existing fiber of execution will yield back to
+the event loop when it performs a blocking operation such as IO or
+sleeping, as it has no more work to do until this blocking operation
+completes. Should a fiber have a lot of CPU bound work to do without any
+intervening blocking operations, however, it is important that execution
+is still yielded back to the event loop periodically.</p>
+<p>This is implemented via <em>preemption</em>: which can only occur at
+specific preemption points. At these points the fiber&#8217;s remaining
+<em>task quota</em> is checked and it has been exceeded the fiber
+yields. The task quota is a measure of how long tasks should be allowed
+to run before yielding to the event loop, and is set to 500 &#181;s by
+default.</p>
+<p>It is important not to starve the event loop, as this would starve
+continuations of futures that weren&#8217;t ready but have since become ready,
+and also starve the important <strong>polling</strong> done by the event
+loop (e.g., checking whether there is new activity on the network card).
+For example, iterating over a large container while doing CPU-bound work
+without any suspension points could starve the reactor and cause a
+<em>reactor stall</em>, which refers to a substantial period of time
+(e.g., more than 20 milliseconds) during which a task does not
+yield.</p>
+<p>Many seastar constructs such as looping constructs have built-in
+preemption points. You may also insert your own preemption points by
+calling <code>seastar::maybe_yield</code>, which performs a preemption
+check. Coroutines will also perform a preemption check at each
+<code>co_await</code>. Note that there is <em>not</em> a preemption
+check between continuations attached to a future with
+<code>then()</code>, so a recursive future loop without explicit
+preemption checks may starve the reactor.</p>

+and above is known to work.</p>
+<p>The simplest way to write efficient asynchronous code with Seastar is
+to use coroutines. Coroutines don&#8217;t share most of the pitfalls of
+traditional continuations (below), and so are the preferred way to write
+new code.</p>
+<p>A coroutine is a function that returns a
+<code>seastar::future&lt;T&gt;</code> and uses the <code>co_await</code>
+or <code>co_return</code> keywords. Coroutines are invisible to their
+callers and callees; they integrate with traditional Seastar code in
+either role. If you are not familiar with C++ coroutines, you may want
+to consult <a href="https://medium.com/pranayaggarwal25/coroutines-in-cpp-15afdf88e17e">A
+more general introduction to C++ coroutines</a>; this section focuses on
+how coroutines integrate with Seastar.</p>
+<p>Here&#8217;s an example of a simple Seastar coroutine:</p>

+<p>In #1, we call the <code>read()</code> function, which returns a
+future. The <code>co_await</code> keyword instructs Seastar to inspect
+the returned future. If the future is ready, then the value (an
+<code>int</code>) is extracted from the future and assigned to
+<code>n</code>. If the future is not ready, the coroutine arranges for
+itself to be called when the future becomes ready, and control is
+returned to Seastar. Once the future becomes ready, the coroutine is
+awakened and the value is extracted from the future and assigned to
+<code>n</code>.</p>
+<p>In #2, we call <code>seastar::sleep()</code> and wait for the
+returned future to become ready, which it will in a second. This
+demonstrates that <code>n</code> is preserved across
+<code>co_await</code> calls, and the author of the coroutine need not
+arrange for storage for coroutine local variables.</p>
+<p>Line #3 demonstrates the addition operation, with which the reader is
+assumed to be familiar.</p>
+<p>In #4, we call a function that returns a
+<code>seastar::future&lt;&gt;</code>. In this case, the future carries
+no value, and so no value is extracted and assigned.</p>
+<p>Line #5 demonstrates returning a value. The integer value is used to
+satisfy the <code>future&lt;int&gt;</code> that our caller got when
+calling the coroutine.</p>

+<p>A lambda function can be a coroutine. Due to an interaction between
+how C++ lambda coroutines are specified and how Seastar coroutines work,
+using lambda coroutines as continuations can result in use-after-free.
+To avoid such problems, take one of the following approaches:</p>
+<ol type="1">
+<li>Use lambda coroutines as arguments to functions that explicitly
+claim support for them</li>
+<li>Wrap lambda coroutines with
+<code>seastar::coroutine::lambda()</code>, and ensure the lambda
+coroutine is fully awaited within the statement it is defined in.</li>
+</ol>

+<h2 data-number="5.2" id="generators-in-coroutines"><span class="header-section-number">5.2</span> Generators in coroutines</h2>
+<p>Sometimes, it would be convenient to model a view of
+<code>input_range</code> with a coroutine which emits the elements one
+after another asynchronously. From the consumer of the view&#8217;s
+perspective, it can retrieve the elements by <code>co_await</code>ing
+the return value of the coroutine. From the coroutine&#8217;s perspective, it
+is able to produce the elements multiple times using
+<code>co_yield</code> without &#8220;leaving&#8221; the coroutine. A function
+producing a sequence of values can be named &#8220;generator&#8221;. But unlike the
+regular coroutine which returns a single
+<code>seastar::future&lt;T&gt;</code>, a generator should return
+<code>seastar::coroutine::experimental::generator&lt;T, Container&gt;</code>.
+Where <code>T</code> is the type of the elements, while
+<code>Container</code> is a template, which is used to store the
+elements. Because, underneath of Seastar&#8217;s generator implementation, a
+bounded buffer is used for holding the elements not yet retrieved by the
+consumer, there is a design decision to make &#8211; what kind of container
+should be used, and what its maximum size should be. To define the
+bounded buffer, developers need to:</p>
+<ol type="1">
+<li>specify the type of the container&#8217;s type by via the second template
+parameter of the <code>generator</code></li>
+<li>specify the size of the bounded buffer by passing the size as the
+first parameter of the generator coroutine. The type of the size have to
+be <code>seastar::coroutine::experimental::buffer_size_t</code>.</li>
+</ol>
+<p>But there is an exception, if the buffer&#8217;s size is one, we assume
+that the programmer is likely to use <code>std::optional</code> for the
+bounded buffer, so it&#8217;s not required to pass the maximum size of the
+buffer as the first parameter in this case. But if a coroutine uses
+<code>std::optional</code> as its buffer, and its function signature
+still lists the size as its first parameter, it will not break anything.
+As this parameter will just be ignored by the underlying
+implementation.</p>

+<p>In this hypothetical kitchen, a chef and a diner are working in
+parallel. Instead of preparing all dishes beforehand, the chef cooks the
+dishes while the diner is consuming them one after another. Under most
+circumstances, neither the chef or the diner is blocked by its peer. The
+dishes are buffered using the specified
+<code>seastar::circular_buffer&lt;Dish&gt;</code>. But if the diner is
+too slow so that there are <code>max_dishes_on_table</code> dishes left
+on the table, the chef would wait until the number of dishes is less
+than this setting. Please note, as explained above, despite that this
+parameter is not referenced by the coroutine&#8217;s body, it is actually
+passed to the generator&#8217;s promise constructor, which in turn creates the
+buffer, as we are not using <code>std::optional</code> here. On the
+other hand, apparently, if there is no dishes on the table, the diner
+would wait for new ones to be prepared by the chef.</p>
+<p>Please note, <code>generator&lt;T, Container&gt;</code> is still at
+its early stage of developing, the public interface this template is

+<p>Both <code>throw</code> and <code>std::rethrow_exception()</code>
+involve managing stack unwinding and exception objects, potentially
+impacting performance. Additionally, the C++ standard permits
+<code>std::rethrow_exception()</code> to create a copy of the exception
+object, introducing further overhead. Fortunately, in certain cases,
+exceptions can also be propagated directly, without throwing or
+rethrowing them. It can be achieved by returning a
+<code>coroutine::exception</code> wrapper. This approach can be
+advantageous when aiming to minimize overhead associated with exception
+handling. But it only works for coroutines which return
+<code>future&lt;T&gt;</code>, not <code>future&lt;&gt;</code>, due to
+the limitations in compilers. In particular, the example above won&#8217;t
+compile if the return type is changed to
+<code>future&lt;&gt;</code>.</p>

+<p>Here, two read() calls are launched concurrently. The coroutine is

+<p>Seastar is generally used for I/O, and coroutines usually launch I/O
+operations and consume their results, with little computation in
+between. But occasionally a long running computation is needed, and this
+risks preventing the reactor from performing I/O and scheduling other
+tasks.</p>
+<p>A coroutine will automatically yield in a <code>co_await</code>
+expression; but in a computation we do not <code>co_await</code>
+anything. We can use the <code>seastar::coroutine::maybe_yield</code>

+continuations</h2>
+<p>We&#8217;ve already seen that Seastar <em>continuations</em> are lambdas,
+passed to the <code>then()</code> method of a future. In the examples
+we&#8217;ve seen so far, lambdas have been nothing more than anonymous
+functions. But C++11 lambdas have one more trick up their sleeve, which
+is extremely important for future-based asynchronous programming in
+Seastar: Lambdas can <strong>capture</strong> state. Consider the
+following example:</p>

+<p>The future operation <code>incr(i)</code> takes some time to complete
+(it needs to sleep a bit first&#8230;), and in that duration, it needs to save
+the <code>i</code> value it is working on. In the early event-driven
+programming models, the programmer needed to explicitly define an object
+for holding this state, and to manage all these objects. Everything is
+much simpler in Seastar, with C++11&#8217;s lambdas: The <em>capture
+syntax</em> &#8220;<code>[i]</code>&#8221; in the above example means that the value
+of i, as it existed when incr() was called() is captured into the
+lambda. The lambda is not just a function - it is in fact an
+<em>object</em>, with both code and data. In essence, the compiler
+created for us automatically the state object, and we neither need to
+define it, nor to keep track of it (it gets saved together with the
+continuation, when the continuation is deferred, and gets deleted
+automatically after the continuation runs).</p>
+<p>One implementation detail worth understanding is that when a
+continuation has captured state and is run immediately, this capture
+incurs no runtime overhead. However, when the continuation cannot be run
+immediately (because the future is not yet ready) and needs to be saved
+till later, memory needs to be allocated on the heap for this data, and
+the continuation&#8217;s captured data needs to be copied there. This has
+runtime overhead, but it is unavoidable, and is very small compared to
+the related overhead in the threaded programming model (in a threaded
+program, this sort of state usually resides on the stack of the blocked
+thread, but the stack is much larger than our tiny capture state, takes
+up a lot of memory and causes a lot of cache pollution on context
+switches between those threads).</p>
+<p>In the above example, we captured <code>i</code> <em>by value</em> -
+i.e., a copy of the value of <code>i</code> was saved into the
+continuation. C++ has two additional capture options: capturing by
+<em>reference</em> and capturing by <em>move</em>:</p>
+<p>Using capture-by-reference in a continuation is usually a mistake,
+and can lead to serious bugs. For example, if in the above example we
+captured a reference to i, instead of copying it,</p>

+<p>this would have meant that the continuation would contain the address
+of <code>i</code>, not its value. But <code>i</code> is a stack
+variable, and the incr() function returns immediately, so when the
+continuation eventually gets to run, long after incr() returns, this
+address will contain unrelated content.</p>
+<p>An exception to the capture-by-reference-is-usually-a-mistake rule is
+the <code>do_with()</code> idiom, which we will introduce later. This
+idiom ensures that an object lives throughout the life of the
+continuation, and makes capture-by-reference possible, and very
+convenient.</p>
+<p>Using capture-by-<em>move</em> in continuations is also very useful
+in Seastar applications. By <strong>moving</strong> an object into a
+continuation, we transfer ownership of this object to the continuation,
+and make it easy for the object to be automatically deleted when the
+continuation ends. For example, consider a traditional function taking a
+<code>std::unique_ptr&lt;T&gt;</code>.</p>

+<p>By using unique_ptr in this way, the caller passes an object to the

+<p>Here the use of <code>std::move()</code> causes obj&#8217;s move-assignment
+is used to move the object from the outer function into the
+continuation. The notion of move (<em>move semantics</em>), introduced
+in C++11, is similar to a shallow copy followed by invalidating the
+source copy (so that the two copies do not co-exist, as forbidden by
+unique_ptr). After moving obj into the continuation, the top-level
+function can no longer use it (in this case it&#8217;s of course ok, because
+we return anyway).</p>
+<p>The <code>[obj = ...]</code> capture syntax we used here is new to
+C++14. This is the main reason why Seastar requires C++14, and does not
+support older C++11 compilers.</p>
+<p>The extra <code>() mutable</code> syntax was needed here because by
+default when C++ captures a value (in this case, the value of
+std::move(obj)) into a lambda, it makes this value read-only, so our
+lambda cannot, in this example, move it again. Adding
+<code>mutable</code> removes this artificial restriction.</p>
+<h2 data-number="6.2" id="evaluation-order-considerations-c14-only"><span class="header-section-number">6.2</span> Evaluation order considerations
+(C++14 only)</h2>
+<p>C++14 (and below) does <em>not</em> guarantee that lambda captures in
+continuations will be evaluated after the futures they relate to are
+evaluated (See
+https://en.cppreference.com/w/cpp/language/eval_order).</p>
+<p>Consequently, avoid the programming pattern below:</p>
+<div class="sourceCode" id="cb35"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb35-1"><a href="#cb35-1" aria-hidden="true" tabindex="-1"></a>    <span class="cf">return</span> do_something<span class="op">(</span>obj<span class="op">).</span>then<span class="op">([</span>obj <span class="op">=</span> <span class="bu">std::</span>move<span class="op">(</span>obj<span class="op">)]</span> <span class="op">()</span> <span class="at">mutable</span> <span class="op">{</span></span>

+<span id="cb35-3"><a href="#cb35-3" aria-hidden="true" tabindex="-1"></a>    <span class="op">});</span></span></code></pre></div>
+<p>In the example above, <code>[obj = std::move(obj)]</code> might be
+evaluated before <code>do_something(obj)</code> is called, potentially
+leading to use-after-move of <code>obj</code>.</p>
+<p>To guarantee the desired evaluation order, the expression above may
+be broken into separate statements as follows:</p>
+<div class="sourceCode" id="cb36"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb36-1"><a href="#cb36-1" aria-hidden="true" tabindex="-1"></a>    <span class="kw">auto</span> fut <span class="op">=</span> do_something<span class="op">(</span>obj<span class="op">);</span></span>

+<p>This was changed in C++17. The expression that creates the object the
+function <code>then</code> is called on (the future) is evaluated before
+all the arguments to the function, so this style is not required in
+C++17 and above.</p>

+<p>An exception thrown in a continuation is implicitly captured by the
+system and stored in the future. A future that stores such an exception
+is similar to a ready future in that it can cause its continuation to be
+launched, but it does not contain a value &#8211; only the exception.</p>
+<p>Calling <code>.then()</code> on such a future skips over the
+continuation, and transfers the exception for the input future (the
+object on which <code>.then()</code> is called) to the output future
+(<code>.then()</code>&#8217;s return value).</p>
+<p>This default handling parallels normal exception behavior &#8211; if an
+exception is thrown in straight-line code, all following lines are
+skipped:</p>

+<p>Usually, aborting the current chain of operations and returning an
+exception is what&#8217;s needed, but sometimes more fine-grained control is
+required. There are several primitives for handling exceptions:</p>
+<ol type="1">
+<li><code>.then_wrapped()</code>: instead of passing the values carried
+by the future into the continuation, <code>.then_wrapped()</code> passes
+the input future to the continuation. The future is guaranteed to be in
+ready state, so the continuation can examine whether it contains a value
+or an exception, and take appropriate action.</li>
+<li><code>.finally()</code>: similar to a Java finally block, a
+<code>.finally()</code> continuation is executed whether or not its
+input future carries an exception or not. The result of the finally
+continuation is its input future, so <code>.finally()</code> can be used
+to insert code in a flow that is executed unconditionally, but otherwise
+does not alter the flow.</li>
+</ol>
+<p>The following example illustrates usage of <code>then_wrapped</code>
+and <code>finally</code>:</p>

+futures</h2>
+<p>An asynchronous function can fail in one of two ways: It can fail
+immediately, by throwing an exception, or it can return a future which
+will eventually fail (resolve to an exception). These two modes of
+failure appear similar to the uninitiated, but behave differently when
+attempting to handle exceptions using <code>finally()</code>,
+<code>handle_exception()</code>, or <code>then_wrapped()</code>. For
+example, consider the code:</p>

+<p>This code will, as expected, print the &#8220;cleaning up&#8221; message - the
+asynchronous function <code>fail()</code> returns a future which
+resolves to a failure, and the <code>finally()</code> continuation is
+run despite this failure, as expected.</p>
+<p>Now consider that in the above example we had a different definition
+for <code>fail()</code>:</p>
+<div class="sourceCode" id="cb42"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb42-1"><a href="#cb42-1" aria-hidden="true" tabindex="-1"></a>seastar<span class="op">::</span>future<span class="op">&lt;&gt;</span> fail<span class="op">()</span> <span class="op">{</span></span>

+<p>Here, <code>fail()</code> does not return a failing future. Rather,
+it fails to return a future at all! The exception it throws stops the
+entire function <code>f()</code>, and the <code>finally()</code>
+continuation does not not get attached to the future (which was never
+returned), and will never run. The &#8220;cleaning up&#8221; message is not printed
+now.</p>
+<p>We recommend that to reduce the chance for such errors, asynchronous
+functions should always return a failed future rather than throw an
+actual exception. If the asynchronous function calls another function
+<em>before</em> returning a future, and that second function might
+throw, it should use <code>try</code>/<code>catch</code> to catch the
+exception and convert it into a failed future:</p>

+<p>Here, <code>fail()</code> catches the exception thrown by
+<code>inner()</code>, whatever it might be, and returns a failed future
+with that failure. Written this way, the <code>finally()</code>
+continuation will be reached, and the &#8220;cleaning up&#8221; message printed.</p>
+<blockquote>
+<p>Despite this recommendation that asynchronous functions avoid
+throwing, some asynchronous functions do throw exceptions in addition to
+returning exceptional futures. A common example are functions which
+allocate memory and throw <code>std::bad_alloc</code> when running out
+of memory, instead of returning a future. The
+<code>future&lt;&gt; seastar::semaphore::wait()</code> method is one
+such function: It returns a future which may be exceptional if the
+semaphore was <code>broken()</code> or the wait timed out, but may also
+<em>throw</em> an exception when failing to allocate memory it needs to
+hold the list of waiters. Therefore, unless a function &#8212; including
+asynchronous functions &#8212; is explicitly tagged &#8220;<code>noexcept</code>&#8221;,
+the application should be prepared to handle exceptions thrown from it.
+In modern C++, code usually uses RAII to be exception-safe without
+sprinkling it with <code>try</code>/<code>catch</code>.
+<code>seastar::defer()</code> is a RAII-based idiom that ensures that
+some cleanup code is run even if an exception is thrown.</p>
+</blockquote>
+<p>Seastar has a convenient generic function,
+<code>futurize_invoke()</code>, which can be useful here.
+<code>futurize_invoke(func, args...)</code> runs a function which may
+return either a future value or an immediate value, and in both cases
+convert the result into a future value. <code>futurize_invoke()</code>
+also converts an immediate exception thrown by the function, if any,
+into a failed future, just like we did above. So using
+<code>futurize_invoke()</code> we can make the above example work even
+if <code>fail()</code> did throw exceptions:</p>

+exception is inside a <em>continuation</em>. Consider the following
+code:</p>

+<p>Here, the lambda function of the first continuation does throw an
+exception instead of returning a failed future. However, we do
+<em>not</em> have the same problem as before, which only happened
+because an asynchronous function threw an exception <em>before</em>
+returning a valid future. Here, <code>f()</code> does return a valid
+future immediately - the failure will only be known later, after
+<code>sleep()</code> resolves. The message in <code>finally()</code>
+will be printed. The methods which attach continuations (such as
+<code>then()</code> and <code>finally()</code>) run the continuation the
+same way, so continuation functions may return immediate values or, in
+this case, throw an immediate exception, and still work properly.</p>

+<p>An asynchronous function starts an operation which may continue long
+after the function returns: The function itself returns a
+<code>future&lt;T&gt;</code> almost immediately, but it may take a while
+until this future is resolved.</p>
+<p>When such an asynchronous operation needs to operate on existing
+objects, or to use temporary objects, we need to worry about the
+<em>lifetime</em> of these objects: We need to ensure that these objects
+do not get destroyed before the asynchronous function completes (or it
+will try to use the freed object and malfunction or crash), and to also
+ensure that the object finally get destroyed when it is no longer needed
+(otherwise we will have a memory leak). Seastar offers a variety of
+mechanisms for safely and efficiently keeping objects alive for the
+right duration. In this section we will explore these mechanisms, and
+when to use each mechanism.</p>
+<h2 data-number="8.1" id="passing-ownership-to-continuation"><span class="header-section-number">8.1</span> Passing ownership to
+continuation</h2>
+<p>The most straightforward way to ensure that an object is alive when a
+continuation runs and is destroyed afterwards is to pass its ownership
+to the continuation. When continuation <em>owns</em> the object, the
+object will be kept until the continuation runs, and will be destroyed
+as soon as the continuation is not needed (i.e., it may have run, or
+skipped in case of exception and <code>then()</code> continuation).</p>
+<p>We already saw above that the way for a continuation to get ownership
+of an object is through <em>capturing</em>:</p>
+<div class="sourceCode" id="cb46"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb46-1"><a href="#cb46-1" aria-hidden="true" tabindex="-1"></a>seastar<span class="op">::</span>future<span class="op">&lt;&gt;</span> slow_incr<span class="op">(</span><span class="dt">int</span> i<span class="op">)</span> <span class="op">{</span></span>

+<span id="cb46-3"><a href="#cb46-3" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>Here the continuation captures the value of <code>i</code>. In other
+words, the continuation includes a copy of <code>i</code>. When the
+continuation runs 10ms later, it will have access to this value, and as
+soon as the continuation finishes its object is destroyed, together with
+its captured copy of <code>i</code>. The continuation owns this copy of
+<code>i</code>.</p>
+<p>Capturing by value as we did here - making a copy of the object we
+need in the continuation - is useful mainly for very small objects such
+as the integer in the previous example. Other objects are expensive to
+copy, or sometimes even cannot be copied. For example, the following is
+<strong>not</strong> a good idea:</p>
+<div class="sourceCode" id="cb47"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb47-1"><a href="#cb47-1" aria-hidden="true" tabindex="-1"></a>seastar<span class="op">::</span>future<span class="op">&lt;&gt;</span> slow_op<span class="op">(</span><span class="bu">std::</span>vector<span class="op">&lt;</span><span class="dt">int</span><span class="op">&gt;</span> v<span class="op">)</span> <span class="op">{</span></span>
+<span id="cb47-2"><a href="#cb47-2" aria-hidden="true" tabindex="-1"></a>    <span class="co">// this makes another copy of v:</span></span>
+<span id="cb47-3"><a href="#cb47-3" aria-hidden="true" tabindex="-1"></a>    <span class="cf">return</span> seastar<span class="op">::</span>sleep<span class="op">(</span><span class="dv">10</span><span class="bu">ms</span><span class="op">).</span>then<span class="op">([</span>v<span class="op">]</span> <span class="op">{</span> <span class="co">/* do something with v */</span> <span class="op">});</span></span>
+<span id="cb47-4"><a href="#cb47-4" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>This would be inefficient - as the vector <code>v</code>, potentially
+very long, will be copied and the copy will be saved in the
+continuation. In this example, there is no reason to copy <code>v</code>
+- it was anyway passed to the function by value and will not be used
+again after capturing it into the continuation, as right after the
+capture, the function returns and destroys its copy of
+<code>v</code>.</p>
+<p>For such cases, C++14 allows <em>moving</em> the object into the
+continuation:</p>
+<div class="sourceCode" id="cb48"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb48-1"><a href="#cb48-1" aria-hidden="true" tabindex="-1"></a>seastar<span class="op">::</span>future<span class="op">&lt;&gt;</span> slow_op<span class="op">(</span><span class="bu">std::</span>vector<span class="op">&lt;</span><span class="dt">int</span><span class="op">&gt;</span> v<span class="op">)</span> <span class="op">{</span></span>
+<span id="cb48-2"><a href="#cb48-2" aria-hidden="true" tabindex="-1"></a>    <span class="co">// v is not copied again, but instead moved:</span></span>
+<span id="cb48-3"><a href="#cb48-3" aria-hidden="true" tabindex="-1"></a>    <span class="cf">return</span> seastar<span class="op">::</span>sleep<span class="op">(</span><span class="dv">10</span><span class="bu">ms</span><span class="op">).</span>then<span class="op">([</span>v <span class="op">=</span> <span class="bu">std::</span>move<span class="op">(</span>v<span class="op">)]</span> <span class="op">{</span> <span class="co">/* do something with v */</span> <span class="op">});</span></span>
+<span id="cb48-4"><a href="#cb48-4" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>Now, instead of copying the object <code>v</code> into the
+continuation, it is <em>moved</em> into the continuation. The
+C++11-introduced move constructor moves the vector&#8217;s data into the
+continuation and clears the original vector. Moving is a quick operation
+- for a vector it only requires copying a few small fields such as the
+pointer to the data. As before, once the continuation is dismissed the
+vector is destroyed - and its data array (which was moved in the move
+operation) is finally freed.</p>
+<p>TODO: talk about temporary_buffer as an example of an object designed
+to be moved in this way.</p>
+<p>In some cases, moving the object is undesirable. For example, some
+code keeps references to an object or one of its fields and the
+references become invalid if the object is moved. In some complex
+objects, even the move constructor is slow. For these cases, C++
+provides the useful wrapper <code>std::unique_ptr&lt;T&gt;</code>. A
+<code>unique_ptr&lt;T&gt;</code> object owns an object of type
+<code>T</code> allocated on the heap. When a
+<code>unique_ptr&lt;T&gt;</code> is moved, the object of type T is not
+touched at all - just the pointer to it is moved. An example of using
+<code>std::unique_ptr&lt;T&gt;</code> in capture is:</p>
+<div class="sourceCode" id="cb49"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb49-1"><a href="#cb49-1" aria-hidden="true" tabindex="-1"></a>seastar<span class="op">::</span>future<span class="op">&lt;&gt;</span> slow_op<span class="op">(</span><span class="bu">std::</span>unique_ptr<span class="op">&lt;</span>T<span class="op">&gt;</span> p<span class="op">)</span> <span class="op">{</span></span>

+<span id="cb49-3"><a href="#cb49-3" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p><code>std::unique_ptr&lt;T&gt;</code> is the standard C++ mechanism
+for passing unique ownership of an object to a function: The object is
+only owned by one piece of code at a time, and ownership is transferred
+by moving the <code>unique_ptr</code> object. A <code>unique_ptr</code>
+cannot be copied: If we try to capture p by value, not by move, we will
+get a compilation error.</p>
+<h2 data-number="8.2" id="keeping-ownership-at-the-caller"><span class="header-section-number">8.2</span> Keeping ownership at the
+caller</h2>
+<p>The technique we described above - giving the continuation ownership
+of the object it needs to work on - is powerful and safe. But often it
+becomes hard and verbose to use. When an asynchronous operation involves
+not just one continuation but a chain of continuations that each needs
+to work on the same object, we need to pass the ownership of the object
+between each successive continuation, which can become inconvenient. It
+is especially inconvenient when we need to pass the same object into two
+separate asynchronous functions (or continuations) - after we move the
+object into one, the object needs to be returned so it can be moved
+again into the second. E.g.,</p>

+<p>This complexity arises because we wanted asynchronous functions and
+continuations to take the ownership of the objects they operated on. A
+simpler approach would be to have the <em>caller</em> of the
+asynchronous function continue to be the owner of the object, and just
+pass <em>references</em> to the object to the various other asynchronous
+functions and continuations which need the object. For example:</p>

+<p>This approach raises a question: The caller of <code>slow_op</code>
+is now responsible for keeping the object <code>o</code> alive while the
+asynchronous code started by <code>slow_op</code> needs this object. But
+how will this caller know how long this object is actually needed by the
+asynchronous operation it started?</p>
+<p>The most reasonable answer is that an asynchronous function may need
+access to its parameters until the future it returns is resolved - at
+which point the asynchronous code completes and no longer needs access
+to its parameters. We therefore recommend that Seastar code adopt the
+following convention:</p>
+<blockquote>
+<p><strong>Whenever an asynchronous function takes a parameter by
+reference, the caller must ensure that the referred object lives until
+the future returned by the function is resolved.</strong></p>
+</blockquote>
+<p>Note that this is merely a convention suggested by Seastar, and
+unfortunately nothing in the C++ language enforces it. C++ programmers
+in non-Seastar programs often pass large objects to functions as a const
+reference just to avoid a slow copy, and assume that the called function
+will <em>not</em> save this reference anywhere. But in Seastar code,
+that is a dangerous practice because even if the asynchronous function
+did not intend to save the reference anywhere, it may end up doing it
+implicitly by passing this reference to another function and eventually
+capturing it in a continuation.</p>
+<blockquote>
+<p>It would be nice if future versions of C++ could help us catch
+incorrect uses of references. Perhaps we could have a tag for a special
+kind of reference, an &#8220;immediate reference&#8221; which a function can use use
+immediately (i.e, before returning a future), but cannot be captured
+into a continuation.</p>
+</blockquote>
+<p>With this convention in place, it is easy to write complex
+asynchronous functions functions like <code>slow_op</code> which pass
+the object around, by reference, until the asynchronous operation is
+done. But how does the caller ensure that the object lives until the
+returned future is resolved? The following is <em>wrong</em>:</p>

+<p>Here, although <code>obj</code> was correctly passed to the lambda by
+reference, we later accidentally passed <code>slow_op()</code> a copy of
+it (because here <code>slow_op</code> takes the object by value, not by
+reference), and this copy will be destroyed as soon as
+<code>slow_op</code> returns, not waiting until the returned future
+resolves.</p>
+<p>When using <code>do_with</code>, always remember it requires adhering
+to the convention described above: The asynchronous function which we
+call inside <code>do_with</code> must not use the objects held by
+<code>do_with</code> <em>after</em> the returned future is resolved. It
+is a serious use-after-free bug for an asynchronous function to return a
+future which resolves while still having background operations using the
+<code>do_with()</code>ed objects.</p>
+<p>In general, it is rarely a good idea for an asynchronous function to
+resolve while leaving behind background operations - even if those
+operations do not use the <code>do_with()</code>ed objects. Background
+operations that we do not wait for may cause us to run out of memory (if
+we don&#8217;t limit their number) and make it difficult to shut down the
+application cleanly.</p>
+<h2 data-number="8.3" id="sharing-ownership-reference-counting"><span class="header-section-number">8.3</span> Sharing ownership (reference
+counting)</h2>
+<p>In the beginning of this chapter, we already noted that capturing a
+copy of an object into a continuation is the simplest way to ensure that
+the object is alive when the continuation runs and destroyed afterwards.
+However, complex objects are often expensive (in time and memory) to
+copy. Some objects cannot be copied at all, or are read-write and the
+continuation should modify the original object, not a new copy. The
+solution to all these issues are <strong>reference counted</strong>,
+a.k.a. <strong>shared</strong> objects:</p>
+<p>A simple example of a reference-counted object in Seastar is a
+<code>seastar::file</code>, an object holding an open file object (we
+will introduce <code>seastar::file</code> in a later section). A
+<code>file</code> object can be copied, but copying does not involve
+copying the file descriptor (let alone the file). Instead, both copies
+point to the same open file, and a reference count is increased by 1.
+When a file object is destroyed, the file&#8217;s reference count is decreased
+by one, and only when the reference count reaches 0 the underlying file
+is actually closed.</p>
+<p>The fact that <code>file</code> objects can be copied very quickly
+and all copies actually point to the same file, make it very convenient
+to pass them to asynchronous code; For example,</p>

+<span id="cb57-5"><a href="#cb57-5" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>Note how calling <code>slow_size</code> is as simple as calling
+<code>slow_size(f)</code>, passing a copy of <code>f</code>, without
+needing to do anything special to ensure that <code>f</code> is only
+destroyed when no longer needed. That simply happens naturally when
+nothing refers to <code>f</code> any more.</p>
+<p>You may wonder why <code>return f.size()</code> in the above example
+is safe: Doesn&#8217;t it start an asynchronous operation on <code>f</code>
+(the file&#8217;s size may be stored on disk, so not immediately available),
+and <code>f</code> may be immediately destroyed when we return and
+nothing keeps holding a copy of <code>f</code>? If <code>f</code> is
+really the last reference, that is indeed a bug, but there is another
+one: the file is never closed. The assumption that makes the code valid
+is that there is another reference to <code>f</code> that will be used
+to close it. The close member function holds on to the reference count
+of that object, so it continues to live even if nothing else keeps
+holding on to it. Since all futures produced by a file object complete
+before it is closed, all that is needed for correctness is to remember
+to always close files.</p>
+<p>The reference counting has a run-time cost, but it is usually very
+small; It is important to remember that Seastar objects are always used
+by a single CPU only, so the reference-count increment and decrement
+operations are not the slow atomic operations often used for reference
+counting, but just regular CPU-local integer operations. Moreover,
+judicious use of <code>std::move()</code> and the compiler&#8217;s optimizer
+can reduce the number of unnecessary back-and-forth increment and
+decrement of the reference count.</p>
+<p>C++11 offers a standard way of creating reference-counted shared
+objects - using the template <code>std::shared_ptr&lt;T&gt;</code>. A
+<code>shared_ptr</code> can be used to wrap any type into a
+reference-counted shared object like <code>seastar::file</code> above.
+However, the standard <code>std::shared_ptr</code> was designed with
+multi-threaded applications in mind so it uses slow atomic
+increment/decrement operations for the reference count which we already
+noted is unnecessary in Seastar. For this reason Seastar offers its own
+single-threaded implementation of this template,
+<code>seastar::shared_ptr&lt;T&gt;</code>. It is similar to
+<code>std::shared_ptr&lt;T&gt;</code> except no atomic operations are
+used.</p>
+<p>Additionally, Seastar also provides an even lower overhead variant of
+<code>shared_ptr</code>: <code>seastar::lw_shared_ptr&lt;T&gt;</code>.
+The full-featured <code>shared_ptr</code> is complicated by the need to
+support polymorphic types correctly (a shared object created of one
+class, and accessed through a pointer to a base class). It makes
+<code>shared_ptr</code> need to add two words to the shared object, and
+two words to each <code>shared_ptr</code> copy. The simplified
+<code>lw_shared_ptr</code> - which does <strong>not</strong> support
+polymorphic types - adds just one word in the object (the reference
+count) and each copy is just one word - just like copying a regular
+pointer. For this reason, the light-weight
+<code>seastar::lw_shared_ptr&lt;T&gt;</code> should be preferred when
+possible (<code>T</code> is not a polymorphic type), otherwise
+<code>seastar::shared_ptr&lt;T&gt;</code>. The slower
+<code>std::shared_ptr&lt;T&gt;</code> should never be used in sharded
+Seastar applications.</p>

+<p>Wouldn&#8217;t it be convenient if we could save objects on a stack just

+becomes invalid - we need to store the value somewhere else. Think if

+<dl class="section note"><dt>Note</dt><dd>The <code>get0()</code> method is deprecated. It's a remnant from older versions of Seastar that supported variadic futures, capable of returning multiple values through a tuple. Back then, <code>get0()</code> served the purpose of retrieving the first (and usually the only) value. Today, the <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get()</a> method accomplishes the same task. However, there's a subtle difference in return types: <code>get0()</code> returned <code>T</code>, while <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get()</a> returns <code>T&amp;&amp;</code> (an rvalue reference to <code>T</code>). This distinction typically won't cause issues when switching from <code>get0()</code> to <a class="el" href="classseastar_1_1future.html#a50bfeff0acccd2f365cce40f9954218c">get()</a>. However, in specific metaprogramming scenarios, especially when the code expects type <code>T</code>, you'll need to use <code>std::remove_reference_t&lt;decltype(fut.get())&gt;</code> to extract the underlying type <code>T</code>. For new code that utilizes <code>future&lt;tuple&lt;...&gt;&gt;</code>, employ <code>std::get&lt;0&gt;</code>(fut.get()) to access the first element of the tuple, rather than the deprecated get0(). </dd></dl>

+</ul>
+<p >source_labels - a list of source labels, the labels are concatenated with the separator and and the combine value is match to the regex. target_label - the labels to perform the action on when replacing a value or when dropping a label. replacement - the string to use when replacing a label value, regex group can be used. expr - a regular expression in a string format. Action would be taken if the regex match the concatenated labels. action - The action to perform when there is a match. separator - separator to use when concatenating the labels. </p>

+<p><strong>Seastar</strong>, which we introduce in this document, is a
+C++ library for writing highly efficient complex server applications on
+modern multi-core machines.</p>
+<p>Traditionally, the programming languages libraries and frameworks
+used for writing server applications have been divided into two distinct
+camps: those focusing on efficiency, and those focusing on complexity.
+Some frameworks are extremely efficient and yet allow building only
+simple applications (e.g., DPDK allows applications which process
+packets individually), while other frameworks allow building extremely
+complex applications, at the cost of run-time efficiency. Seastar is our
+attempt to get the best of both worlds: To create a library which allows
+building highly complex server applications, and yet achieve optimal
+performance.</p>
+<p>The inspiration and first use case of Seastar was Scylla, a rewrite
+of Apache Cassandra. Cassandra is a very complex application, and yet,
+with Seastar we were able to re-implement it with as much as 10-fold
+throughput increase, as well as significantly lower and more consistent
+latencies.</p>
+<p>Seastar offers a complete asynchronous programming framework, which
+uses two concepts - <strong>futures</strong> and
+<strong>continuations</strong> - to uniformly represent, and handle,
+every type of asynchronous event, including network I/O, disk I/O, and
+complex combinations of other events.</p>
+<p>Since modern multi-core and multi-socket machines have steep
+penalties for sharing data between cores (atomic instructions, cache
+line bouncing and memory fences), Seastar programs use the share-nothing
+programming model, i.e., the available memory is divided between the
+cores, each core works on data in its own part of memory, and
+communication between cores happens via explicit message passing (which
+itself happens using the SMP’s shared memory hardware, of course).</p>
+<h2 data-number="1.1" id="asynchronous-programming"><span class="header-section-number">1.1</span> Asynchronous programming</h2>
+<p>A server for a network protocol, such as the classic HTTP (Web) or
+SMTP (e-mail) servers, inherently deals with parallelism: Multiple
+clients send requests in parallel, and we cannot finish handling one
+request before starting to handle the next: A request may, and often
+does, need to block because of various reasons — a full TCP window
+(i.e., a slow connection), disk I/O, or even the client holding on to an
+inactive connection — and the server needs to handle other connections
+as well.</p>
+<p>The most straightforward way to handle such parallel connections,
+employed by classic network servers such as Inetd, Apache Httpd and
+Sendmail, is to use a separate operating-system process per connection.
+This technique evolved over the years to improve its performance: At
+first, a new process was spawned to handle each new connection; Later, a
+pool of existing processes was kept and each new connection was assigned
+to an unemployed process from the pool; Finally, the processes were
+replaced by threads. However, the common idea behind all these
+implementations is that at each moment, each process handles exclusively
+a single connection. Therefore, the server code is free to use blocking
+system calls, such as reading or writing to a connection, or reading
+from disk, and if this process blocks, all is well because we have many
+additional processes ready to handle other connections.</p>
+<p>Programming a server which uses a process (or a thread) per
+connection is known as <em>synchronous</em> programming, because the
+code is written linearly, and one line of code starts to run after the
+previous line finished. For example, the code may read a request from a
+socket, parse the request, and then piecemeal read a file from disk and
+write it back to the socket. Such code is easy to write, almost like
+traditional non-parallel programs. In fact, it’s even possible to run an
+external non-parallel program to handle each request — this is for
+example how Apache HTTPd ran “CGI” programs, the first implementation of
+dynamic Web-page generation.</p>
+<blockquote>
+<p>NOTE: although the synchronous server application is written in a
+linear, non-parallel, fashion, behind the scenes the kernel helps ensure
+that everything happens in parallel and the machine’s resources — CPUs,
+disk and network — are fully utilized. Beyond the process parallelism
+(we have multiple processes handling multiple connections in parallel),
+the kernel may even parallelize the work of one individual connection —
+for example process an outstanding disk request (e.g., read from a disk
+file) in parallel with handling the network connection (send
+buffered-but-yet-unsent data, and buffer newly-received data until the
+application is ready to read it).</p>
+</blockquote>
+<p>But synchronous, process-per-connection, server programming didn’t
+come without disadvantages and costs. Slowly but surely, server authors
+realized that starting a new process is slow, context switching is slow,
+and each process comes with significant overheads — most notably the
+size of its stack. Server and kernel authors worked hard to mitigate
+these overheads: They switched from processes to threads, from creating
+new threads to thread pools, they lowered default stack size of each
+thread, and increased the virtual memory size to allow more
+partially-utilized stacks. But still, servers with synchronous designs
+had unsatisfactory performance, and scaled badly as the number of
+concurrent connections grew. In 1999, Dan Kegel popularized “the C10K
+problem”, the need of a single server to efficiently handle 10,000
+concurrent connections — most of them slow or even inactive.</p>
+<p>The solution, which became popular in the following decade, was to
+abandon the cozy but inefficient synchronous server design, and switch
+to a new type of server design — the <em>asynchronous</em>, or
+<em>event-driven</em>, server. An event-driven server has just one
+thread, or more accurately, one thread per CPU. This single thread runs
+a tight loop which, at each iteration, checks, using <code>poll()</code>
+(or the more efficient <code>epoll</code>) for new events on many open
+file descriptors, e.g., sockets. For example, an event can be a socket
+becoming readable (new data has arrived from the remote end) or becoming
+writable (we can send more data on this connection). The application
+handles this event by doing some non-blocking operations, modifying one
+or more of the file descriptors, and maintaining its knowledge of the
+<em>state</em> of this connection.</p>
+<p>However, writers of asynchronous server applications faced, and still
+face today, two significant challenges:</p>
+<ul>
+<li><p><strong>Complexity:</strong> Writing a simple asynchronous server
+is straightforward. But writing a <em>complex</em> asynchronous server
+is notoriously difficult. The handling of a single connection, instead
+of being a simple easy-to-read function call, now involves a large
+number of small callback functions, and a complex state machine to
+remember which function needs to be called when each event
+occurs.</p></li>
+<li><p><strong>Non-blocking:</strong> Having just one thread per core is
+important for the performance of the server application, because context
+switches are slow. However, if we only have one thread per core, the
+event-handling functions must <em>never</em> block, or the core will
+remain idle. But some existing programming languages and frameworks
+leave the server author no choice but to use blocking functions, and
+therefore multiple threads. For example, <code>Cassandra</code> was
+written as an asynchronous server application; But because disk I/O was
+implemented with <code>mmap</code>ed files, which can uncontrollably
+block the whole thread when accessed, they are forced to run multiple
+threads per CPU.</p></li>
+</ul>
+<p>Moreover, when the best possible performance is desired, the server
+application, and its programming framework, has no choice but to also
+take the following into account:</p>
+<ul>
+<li><p><strong>Modern Machines</strong>: Modern machines are very
+different from those of just 10 years ago. They have many cores and deep
+memory hierarchies (from L1 caches to NUMA) which reward certain
+programming practices and penalizes others: Unscalable programming
+practices (such as taking locks) can devastate performance on many
+cores; Shared memory and lock-free synchronization primitives are
+available (i.e., atomic operations and memory-ordering fences) but are
+dramatically slower than operations that involve only data in a single
+core’s cache, and also prevent the application from scaling to many
+cores.</p></li>
+<li><p><strong>Programming Language:</strong> High-level languages such
+Java, Javascript, and similar “modern” languages are convenient, but
+each comes with its own set of assumptions which conflict with the
+requirements listed above. These languages, aiming to be portable, also
+give the programmer less control over the performance of critical code.
+For really optimal performance, we need a programming language which
+gives the programmer full control, zero run-time overheads, and on the
+other hand — sophisticated compile-time code generation and
+optimization.</p></li>
+</ul>
+<p>Seastar is a framework for writing asynchronous server applications
+which aims to solve all four of the above challenges: It is a framework
+for writing <em>complex</em> asynchronous applications involving both
+network and disk I/O. The framework’s fast path is entirely
+single-threaded (per core), scalable to many cores and minimizes the use
+of costly sharing of memory between cores. It is a C++14 library, giving
+the user sophisticated compile-time features and full control over
+performance, without run-time overhead.</p>
+<h2 data-number="1.2" id="seastar"><span class="header-section-number">1.2</span> Seastar</h2>
+<p>Seastar is an event-driven framework allowing you to write
+non-blocking, asynchronous code in a relatively straightforward manner
+(once understood). Its APIs are based on futures. Seastar utilizes the
+following concepts to achieve extreme performance:</p>
+<ul>
+<li><strong>Cooperative micro-task scheduler</strong>: instead of
+running threads, each core runs a cooperative task scheduler. Each task
+is typically very lightweight – only running for as long as it takes to
+process the last I/O operation’s result and to submit a new one.</li>
+<li><strong>Share-nothing SMP architecture</strong>: each core runs
+independently of other cores in an SMP system. Memory, data structures,
+and CPU time are not shared; instead, inter-core communication uses
+explicit message passing. A Seastar core is often termed a shard. TODO:
+more here https://github.com/scylladb/seastar/wiki/SMP</li>
+<li><strong>Future based APIs</strong>: futures allow you to submit an
+I/O operation and to chain tasks to be executed on completion of the I/O
+operation. It is easy to run multiple I/O operations in parallel - for
+example, in response to a request coming from a TCP connection, you can
+issue multiple disk I/O requests, send messages to other cores on the
+same system, or send requests to other nodes in the cluster, wait for
+some or all of the results to complete, aggregate the results, and send
+a response.</li>
+<li><strong>Share-nothing TCP stack</strong>: while Seastar can use the
+host operating system’s TCP stack, it also provides its own
+high-performance TCP/IP stack built on top of the task scheduler and the
+share-nothing architecture. The stack provides zero-copy in both
+directions: you can process data directly from the TCP stack’s buffers,
+and send the contents of your own data structures as part of a message
+without incurring a copy. Read more…</li>
+<li><strong>DMA-based storage APIs</strong>: as with the networking
+stack, Seastar provides zero-copy storage APIs, allowing you to DMA your
+data to and from your storage devices.</li>
+</ul>
+<p>This tutorial is intended for developers already familiar with the
+C++ language, and will cover how to use Seastar to create a new
+application.</p>

+<p>As we do in this example, each Seastar program must define and run,
+an <code>app_template</code> object. This object starts the main event
+loop (the Seastar <em>engine</em>) on one or more CPUs, and then runs
+the given function - in this case an unnamed function, a <em>lambda</em>
+- once.</p>
+<p>The <code>return make_ready_future&lt;&gt;();</code> causes the event
+loop, and the whole application, to exit immediately after printing the
+“Hello World” message. In a more typical Seastar application, we will
+want event loop to remain alive and process incoming packets (for
+example), until explicitly exited. Such applications will return a
+<em>future</em> which determines when to exit the application. We will
+introduce futures and how to use them below. In any case, the regular C
+<code>exit()</code> should not be used, because it prevents Seastar or
+the application from cleaning up appropriately.</p>
+<p>As shown in this example, all Seastar functions and types live in the
+“<code>seastar</code>” namespace. An user can either type this namespace
+prefix every time, or use shortcuts like
+“<code>using seastar::app_template</code>” or even
+“<code>using namespace seastar</code>” to avoid typing this prefix. We
+generally recommend to use the namespace prefixes <code>seastar</code>
+and <code>std</code> explicitly, and will follow this style in all the
+examples below.</p>
+<p>To compile this program (it’s present in the
+<code>demos/hello-world.cc</code> file) you can just use Docker.</p>
+<pre><code>$ docker build -t seastar-dev  -f ./docker/dev/Dockerfile .
+$ scripts/build.sh dev
+$ docker run -it --rm -v $(pwd):/seastar seastar-dev /seastar/build/dev/demos/hello-world_demo -c1</code></pre>
+<p>Without the docker help, first make sure you have downloaded, built,
+and optionally installed Seastar, and put the above program in a source
+file anywhere you want, let’s call the file
+<code>getting-started.cc</code>.</p>
+<p>Linux’s <a href="http://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</a>
+is one way for easily determining the compilation and linking parameters
+needed for using various libraries - such as Seastar. For example, if
+Seastar was built in the directory <code>$SEASTAR</code> but not
+installed, one can compile <code>getting-started.cc</code> with it using
+the command:</p>
+<pre><code>c++ getting-started.cc `pkg-config --cflags --libs --static $SEASTAR/build/release/seastar.pc`</code></pre>
+<p>The “<code>--static</code>” is needed because currently, Seastar is
+built as a static library, so we need to tell <code>pkg-config</code> to
+include its dependencies in the link command (whereas, had Seastar been
+a shared library, it could have pulled in its own dependencies).</p>
+<p>If Seastar <em>was</em> installed, the <code>pkg-config</code>
+command line is even shorter:</p>
+<pre><code>c++ getting-started.cc `pkg-config --cflags --libs --static seastar`</code></pre>
+<p>Alternatively, one can easily build a Seastar program with CMake.
+Given the following <code>CMakeLists.txt</code></p>

+<p>As explained in the introduction, Seastar-based programs run a single
+thread on each CPU. Each of these threads runs its own event loop, known
+as the <em>engine</em> in Seastar nomenclature. By default, the Seastar
+application will take over all the available cores, starting one thread
+per core. We can see this with the following program, printing
+<code>seastar::smp::count</code> which is the number of started
+threads:</p>

+<p>On a machine with 4 hardware threads (two cores, and hyperthreading
+enabled), Seastar will by default start 4 engine threads:</p>
+<pre class="none"><code>$ ./a.out
+4</code></pre>
+<p>Each of these 4 engine threads will be pinned (a la
+<strong>taskset(1)</strong>) to a different hardware thread. Note how,
+as we mentioned above, the app’s initialization function is run only on
+one thread, so we see the ouput “4” only once. Later in the tutorial
+we’ll see how to make use of all threads.</p>
+<p>The user can pass a command line parameter, <code>-c</code>, to tell
+Seastar to start fewer threads than the available number of hardware
+threads. For example, to start Seastar on only 2 threads, the user can
+do:</p>
+<pre class="none"><code>$ ./a.out -c2
+2</code></pre>
+<p>When the machine is configured as in the example above - two cores
+with two hyperthreads on each - and only two threads are requested,
+Seastar ensures that each thread is pinned to a different core, and we
+don’t get the two threads competing as hyperthreads of the same core
+(which would, of course, damage performance).</p>
+<p>We cannot start more threads than the number of hardware threads, as
+allowing this will be grossly inefficient. Trying it will result in an
+error:</p>
+<pre class="none"><code>$ ./a.out -c5
+Could not initialize seastar: std::runtime_error (insufficient processing units)</code></pre>
+<p>The error is an exception thrown from app.run, which was caught by
+seastar itself and turned into a non-zero exit code. Note that catching
+the exceptions this way does <strong>not</strong> catch exceptions
+thrown in the application’s actual asynchronous code. We will discuss
+these later in this tutorial.</p>
+<h2 data-number="3.2" id="seastar-memory"><span class="header-section-number">3.2</span> Seastar memory</h2>
+<p>As explained in the introduction, Seastar applications shard their
+memory. Each thread is preallocated with a large piece of memory (on the
+same NUMA node it is running on), and uses only that memory for its
+allocations (such as <code>malloc()</code> or <code>new</code>).</p>
+<p>By default, the machine’s <strong>entire memory</strong> except a
+certain reservation left for the OS (defaulting to the maximum of 1.5G
+or 7% of total memory) is pre-allocated for the application in this
+manner. This default can be changed by <em>either</em> changing the
+amount reserved for the OS (not used by Seastar) with the
+<code>--reserve-memory</code> option, or by explicitly giving the amount
+of memory given to the Seastar application, with the <code>-m</code>
+option. This amount of memory can be in bytes, or using the units “k”,
+“M”, “G” or “T”. These units use the power-of-two values: “M” is a
+<strong>mebibyte</strong>, 2^20 (=1,048,576) bytes, not a
+<strong>megabyte</strong> (10^6 or 1,000,000 bytes).</p>
+<p>Trying to give Seastar more memory than physical memory immediately
+fails:</p>
+<pre class="none"><code>$ ./a.out -m10T
+Couldn&#39;t start application: std::runtime_error (insufficient physical memory)</code></pre>
+<h1 data-number="4" id="introducing-futures-and-continuations"><span class="header-section-number">4</span> Introducing futures and
+continuations</h1>
+<p>Futures and continuations, which we will introduce now, are the
+building blocks of asynchronous programming in Seastar. Their strength
+lies in the ease of composing them together into a large, complex,
+asynchronous program, while keeping the code fairly readable and
+understandable.</p>
+<p>A <a href="\ref%20future">future</a> is a result of a computation
+that may not be available yet. Examples include:</p>
+<ul>
+<li>a data buffer that we are reading from the network</li>
+<li>the expiration of a timer</li>
+<li>the completion of a disk write</li>
+<li>the result of a computation that requires the values from one or
+more other futures.</li>
+</ul>
+<p>The type <code>future&lt;int&gt;</code> variable holds an int that
+will eventually be available - at this point might already be available,
+or might not be available yet. The method available() tests if a value
+is already available, and the method get() gets the value. The type
+<code>future&lt;&gt;</code> indicates something which will eventually
+complete, but not return any value.</p>
+<p>A future is usually returned by an <strong>asynchronous
+function</strong>, a function which returns a future and arranges for
+this future to be eventually resolved. Because asynchronous functions
+<em>promise</em> to eventually resolve the future which they returned,
+asynchronous functions are sometimes called “promises”; But we will
+avoid this term because it tends to confuse more than it explains.</p>
+<p>One simple example of an asynchronous function is Seastar’s function
+sleep():</p>
+<div class="sourceCode" id="cb13"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb13-1"><a href="#cb13-1" aria-hidden="true" tabindex="-1"></a>future<span class="op">&lt;&gt;</span> sleep<span class="op">(</span><span class="bu">std::</span>chrono<span class="bu">::</span>duration<span class="op">&lt;</span>Rep<span class="op">,</span> Period<span class="op">&gt;</span> dur<span class="op">);</span></span></code></pre></div>
+<p>This function arranges a timer so that the returned future becomes
+available (without an associated value) when the given time duration
+elapses.</p>
+<p>A <strong>continuation</strong> is a callback (typically a lambda) to
+run when a future becomes available. A continuation is attached to a
+future with the <code>then()</code> method. Here is a simple
+example:</p>

+<p>In this example we see us getting a future from
+<code>seastar::sleep(1s)</code>, and attaching to it a continuation
+which prints a “Done.” message. The future will become available after 1
+second has passed, at which point the continuation is executed. Running
+this program, we indeed see the message “Sleeping…” immediately, and one
+second later the message “Done.” appears and the program exits.</p>
+<p>The return value of <code>then()</code> is itself a future which is
+useful for chaining multiple continuations one after another, as we will
+explain below. But here we just note that we <code>return</code> this
+future from <code>app.run</code>’s function, so that the program will
+exit only after both the sleep and its continuation are done.</p>
+<p>To avoid repeating the boilerplate “app_engine” part in every code
+example in this tutorial, let’s create a simple main() with which we
+will compile the following examples. This main just calls function
+<code>future&lt;&gt; f()</code>, does the appropriate exception
+handling, and exits when the future returned by <code>f</code> is
+resolved:</p>

+<p>Each <code>sleep()</code> and <code>then()</code> call returns
+immediately: <code>sleep()</code> just starts the requested timer, and
+<code>then()</code> sets up the function to call when the timer expires.
+So all three lines happen immediately and f returns. Only then, the
+event loop starts to wait for the three outstanding futures to become
+ready, and when each one becomes ready, the continuation attached to it
+is run. The output of the above program is of course:</p>
+<pre class="none"><code>$ ./a.out
+Sleeping... 100ms 200ms Done.</code></pre>
+<p><code>sleep()</code> returns <code>future&lt;&gt;</code>, meaning it
+will complete at a future time, but once complete, does not return any
+value. More interesting futures do specify a value of any type (or
+multiple values) that will become available later. In the following
+example, we have a function returning a <code>future&lt;int&gt;</code>,
+and a continuation to be run once this value becomes available. Note how

+<p>The function <code>slow()</code> deserves more explanation. As usual,
+this function returns a <code>future&lt;int&gt;</code> immediately, and
+doesn’t wait for the sleep to complete, and the code in <code>f()</code>
+can chain a continuation to this future’s completion. The future
+returned by <code>slow()</code> is itself a chain of futures: It will
+become ready once sleep’s future becomes ready and then the value 3 is
+returned. We’ll explain below in more details how <code>then()</code>
+returns a future, and how this allows <em>chaining</em> futures.</p>
+<p>This example begins to show the convenience of the futures
+programming model, which allows the programmer to neatly encapsulate
+complex asynchronous operations. <code>slow()</code> might involve a
+complex asynchronous operation requiring multiple steps, but its user
+can use it just as easily as a simple <code>sleep()</code>, and
+Seastar’s engine takes care of running the continuations whose futures
+have become ready at the right time.</p>
+<h2 data-number="4.1" id="ready-futures"><span class="header-section-number">4.1</span> Ready futures</h2>
+<p>A future value might already be ready when <code>then()</code> is
+called to chain a continuation to it. This important case is optimized,
+and the continuation is run immediately instead of being registered to
+run later in the next iteration of the event loop.</p>
+<p><code>make_ready_future&lt;&gt;</code> can be used to return a future
+which is already ready. The following example is identical to the
+previous one, except the promise function <code>fast()</code> returns a
+future which is already ready, and not one which will be ready in a
+second as in the previous example. The nice thing is that the consumer
+of the future does not care, and uses the future in the same way in both
+cases.</p>

+<p>As described above, an existing fiber of execution will yield back to
+the event loop when it performs a blocking operation such as IO or
+sleeping, as it has no more work to do until this blocking operation
+completes. Should a fiber have a lot of CPU bound work to do without any
+intervening blocking operations, however, it is important that execution
+is still yielded back to the event loop periodically.</p>
+<p>This is implemented via <em>preemption</em>: which can only occur at
+specific preemption points. At these points the fiber’s remaining
+<em>task quota</em> is checked and it has been exceeded the fiber
+yields. The task quota is a measure of how long tasks should be allowed
+to run before yielding to the event loop, and is set to 500 µs by
+default.</p>
+<p>It is important not to starve the event loop, as this would starve
+continuations of futures that weren’t ready but have since become ready,
+and also starve the important <strong>polling</strong> done by the event
+loop (e.g., checking whether there is new activity on the network card).
+For example, iterating over a large container while doing CPU-bound work
+without any suspension points could starve the reactor and cause a
+<em>reactor stall</em>, which refers to a substantial period of time
+(e.g., more than 20 milliseconds) during which a task does not
+yield.</p>
+<p>Many seastar constructs such as looping constructs have built-in
+preemption points. You may also insert your own preemption points by
+calling <code>seastar::maybe_yield</code>, which performs a preemption
+check. Coroutines will also perform a preemption check at each
+<code>co_await</code>. Note that there is <em>not</em> a preemption
+check between continuations attached to a future with
+<code>then()</code>, so a recursive future loop without explicit
+preemption checks may starve the reactor.</p>
+<h1 data-number="5" id="coroutines"><span class="header-section-number">5</span> Coroutines</h1>
+<p>Note: coroutines require C++20 and a supporting compiler. Clang 10
+and above is known to work.</p>
+<p>The simplest way to write efficient asynchronous code with Seastar is
+to use coroutines. Coroutines don’t share most of the pitfalls of
+traditional continuations (below), and so are the preferred way to write
+new code.</p>
+<p>A coroutine is a function that returns a
+<code>seastar::future&lt;T&gt;</code> and uses the <code>co_await</code>
+or <code>co_return</code> keywords. Coroutines are invisible to their
+callers and callees; they integrate with traditional Seastar code in
+either role. If you are not familiar with C++ coroutines, you may want
+to consult <a href="https://medium.com/pranayaggarwal25/coroutines-in-cpp-15afdf88e17e">A

+<p>In #1, we call the <code>read()</code> function, which returns a
+future. The <code>co_await</code> keyword instructs Seastar to inspect
+the returned future. If the future is ready, then the value (an
+<code>int</code>) is extracted from the future and assigned to
+<code>n</code>. If the future is not ready, the coroutine arranges for
+itself to be called when the future becomes ready, and control is
+returned to Seastar. Once the future becomes ready, the coroutine is
+awakened and the value is extracted from the future and assigned to
+<code>n</code>.</p>
+<p>In #2, we call <code>seastar::sleep()</code> and wait for the
+returned future to become ready, which it will in a second. This
+demonstrates that <code>n</code> is preserved across
+<code>co_await</code> calls, and the author of the coroutine need not
+arrange for storage for coroutine local variables.</p>
+<p>Line #3 demonstrates the addition operation, with which the reader is
+assumed to be familiar.</p>
+<p>In #4, we call a function that returns a
+<code>seastar::future&lt;&gt;</code>. In this case, the future carries
+no value, and so no value is extracted and assigned.</p>
+<p>Line #5 demonstrates returning a value. The integer value is used to
+satisfy the <code>future&lt;int&gt;</code> that our caller got when
+calling the coroutine.</p>

+<p>A lambda function can be a coroutine. Due to an interaction between

+To avoid such problems, take one of the following approaches:</p>

+after another asynchronously. From the consumer of the view’s
+perspective, it can retrieve the elements by <code>co_await</code>ing
+the return value of the coroutine. From the coroutine’s perspective, it
+is able to produce the elements multiple times using
+<code>co_yield</code> without “leaving” the coroutine. A function
+producing a sequence of values can be named “generator”. But unlike the
+regular coroutine which returns a single
+<code>seastar::future&lt;T&gt;</code>, a generator should return
+<code>seastar::coroutine::experimental::generator&lt;T, Container&gt;</code>.
+Where <code>T</code> is the type of the elements, while
+<code>Container</code> is a template, which is used to store the
+elements. Because, underneath of Seastar’s generator implementation, a
+bounded buffer is used for holding the elements not yet retrieved by the
+consumer, there is a design decision to make – what kind of container
+should be used, and what its maximum size should be. To define the
+bounded buffer, developers need to:</p>
+<ol type="1">
+<li>specify the type of the container’s type by via the second template
+parameter of the <code>generator</code></li>
+<li>specify the size of the bounded buffer by passing the size as the
+first parameter of the generator coroutine. The type of the size have to
+be <code>seastar::coroutine::experimental::buffer_size_t</code>.</li>
+</ol>
+<p>But there is an exception, if the buffer’s size is one, we assume
+that the programmer is likely to use <code>std::optional</code> for the
+bounded buffer, so it’s not required to pass the maximum size of the
+buffer as the first parameter in this case. But if a coroutine uses
+<code>std::optional</code> as its buffer, and its function signature
+still lists the size as its first parameter, it will not break anything.
+As this parameter will just be ignored by the underlying
+implementation.</p>

+<p>In this hypothetical kitchen, a chef and a diner are working in
+parallel. Instead of preparing all dishes beforehand, the chef cooks the
+dishes while the diner is consuming them one after another. Under most
+circumstances, neither the chef or the diner is blocked by its peer. The
+dishes are buffered using the specified
+<code>seastar::circular_buffer&lt;Dish&gt;</code>. But if the diner is
+too slow so that there are <code>max_dishes_on_table</code> dishes left
+on the table, the chef would wait until the number of dishes is less
+than this setting. Please note, as explained above, despite that this
+parameter is not referenced by the coroutine’s body, it is actually
+passed to the generator’s promise constructor, which in turn creates the
+buffer, as we are not using <code>std::optional</code> here. On the
+other hand, apparently, if there is no dishes on the table, the diner
+would wait for new ones to be prepared by the chef.</p>
+<p>Please note, <code>generator&lt;T, Container&gt;</code> is still at
+its early stage of developing, the public interface this template is
+subject to change before it is stabilized enough.</p>

+<p>Both <code>throw</code> and <code>std::rethrow_exception()</code>
+involve managing stack unwinding and exception objects, potentially
+impacting performance. Additionally, the C++ standard permits
+<code>std::rethrow_exception()</code> to create a copy of the exception
+object, introducing further overhead. Fortunately, in certain cases,
+exceptions can also be propagated directly, without throwing or
+rethrowing them. It can be achieved by returning a
+<code>coroutine::exception</code> wrapper. This approach can be
+advantageous when aiming to minimize overhead associated with exception
+handling. But it only works for coroutines which return
+<code>future&lt;T&gt;</code>, not <code>future&lt;&gt;</code>, due to
+the limitations in compilers. In particular, the example above won’t
+compile if the return type is changed to
+<code>future&lt;&gt;</code>.</p>

+<p>The future operation <code>incr(i)</code> takes some time to complete
+(it needs to sleep a bit first…), and in that duration, it needs to save
+the <code>i</code> value it is working on. In the early event-driven
+programming models, the programmer needed to explicitly define an object
+for holding this state, and to manage all these objects. Everything is
+much simpler in Seastar, with C++11’s lambdas: The <em>capture
+syntax</em> “<code>[i]</code>” in the above example means that the value
+of i, as it existed when incr() was called() is captured into the
+lambda. The lambda is not just a function - it is in fact an
+<em>object</em>, with both code and data. In essence, the compiler
+created for us automatically the state object, and we neither need to
+define it, nor to keep track of it (it gets saved together with the
+continuation, when the continuation is deferred, and gets deleted
+automatically after the continuation runs).</p>
+<p>One implementation detail worth understanding is that when a
+continuation has captured state and is run immediately, this capture
+incurs no runtime overhead. However, when the continuation cannot be run
+immediately (because the future is not yet ready) and needs to be saved
+till later, memory needs to be allocated on the heap for this data, and
+the continuation’s captured data needs to be copied there. This has
+runtime overhead, but it is unavoidable, and is very small compared to
+the related overhead in the threaded programming model (in a threaded
+program, this sort of state usually resides on the stack of the blocked
+thread, but the stack is much larger than our tiny capture state, takes
+up a lot of memory and causes a lot of cache pollution on context
+switches between those threads).</p>
+<p>In the above example, we captured <code>i</code> <em>by value</em> -
+i.e., a copy of the value of <code>i</code> was saved into the
+continuation. C++ has two additional capture options: capturing by
+<em>reference</em> and capturing by <em>move</em>:</p>
+<p>Using capture-by-reference in a continuation is usually a mistake,
+and can lead to serious bugs. For example, if in the above example we
+captured a reference to i, instead of copying it,</p>

+<p>this would have meant that the continuation would contain the address
+of <code>i</code>, not its value. But <code>i</code> is a stack
+variable, and the incr() function returns immediately, so when the
+continuation eventually gets to run, long after incr() returns, this
+address will contain unrelated content.</p>
+<p>An exception to the capture-by-reference-is-usually-a-mistake rule is
+the <code>do_with()</code> idiom, which we will introduce later. This
+idiom ensures that an object lives throughout the life of the
+continuation, and makes capture-by-reference possible, and very
+convenient.</p>
+<p>Using capture-by-<em>move</em> in continuations is also very useful
+in Seastar applications. By <strong>moving</strong> an object into a
+continuation, we transfer ownership of this object to the continuation,
+and make it easy for the object to be automatically deleted when the
+continuation ends. For example, consider a traditional function taking a
+<code>std::unique_ptr&lt;T&gt;</code>.</p>

+<p>Here the use of <code>std::move()</code> causes obj’s move-assignment
+is used to move the object from the outer function into the
+continuation. The notion of move (<em>move semantics</em>), introduced
+in C++11, is similar to a shallow copy followed by invalidating the
+source copy (so that the two copies do not co-exist, as forbidden by
+unique_ptr). After moving obj into the continuation, the top-level
+function can no longer use it (in this case it’s of course ok, because
+we return anyway).</p>
+<p>The <code>[obj = ...]</code> capture syntax we used here is new to
+C++14. This is the main reason why Seastar requires C++14, and does not
+support older C++11 compilers.</p>
+<p>The extra <code>() mutable</code> syntax was needed here because by
+default when C++ captures a value (in this case, the value of
+std::move(obj)) into a lambda, it makes this value read-only, so our
+lambda cannot, in this example, move it again. Adding
+<code>mutable</code> removes this artificial restriction.</p>

+<p>Usually, aborting the current chain of operations and returning an
+exception is what’s needed, but sometimes more fine-grained control is
+required. There are several primitives for handling exceptions:</p>
+<ol type="1">
+<li><code>.then_wrapped()</code>: instead of passing the values carried
+by the future into the continuation, <code>.then_wrapped()</code> passes
+the input future to the continuation. The future is guaranteed to be in
+ready state, so the continuation can examine whether it contains a value
+or an exception, and take appropriate action.</li>
+<li><code>.finally()</code>: similar to a Java finally block, a
+<code>.finally()</code> continuation is executed whether or not its
+input future carries an exception or not. The result of the finally
+continuation is its input future, so <code>.finally()</code> can be used
+to insert code in a flow that is executed unconditionally, but otherwise
+does not alter the flow.</li>
+</ol>
+<p>The following example illustrates usage of <code>then_wrapped</code>
+and <code>finally</code>:</p>

+<p>An asynchronous function can fail in one of two ways: It can fail
+immediately, by throwing an exception, or it can return a future which
+will eventually fail (resolve to an exception). These two modes of
+failure appear similar to the uninitiated, but behave differently when
+attempting to handle exceptions using <code>finally()</code>,
+<code>handle_exception()</code>, or <code>then_wrapped()</code>. For
+example, consider the code:</p>

+<p>This code will, as expected, print the “cleaning up” message - the

+run despite this failure, as expected.</p>
+<p>Now consider that in the above example we had a different definition

+returned), and will never run. The “cleaning up” message is not printed
+now.</p>
+<p>We recommend that to reduce the chance for such errors, asynchronous
+functions should always return a failed future rather than throw an
+actual exception. If the asynchronous function calls another function
+<em>before</em> returning a future, and that second function might
+throw, it should use <code>try</code>/<code>catch</code> to catch the

+<p>Here, <code>fail()</code> catches the exception thrown by
+<code>inner()</code>, whatever it might be, and returns a failed future
+with that failure. Written this way, the <code>finally()</code>
+continuation will be reached, and the “cleaning up” message printed.</p>
+<blockquote>
+<p>Despite this recommendation that asynchronous functions avoid
+throwing, some asynchronous functions do throw exceptions in addition to
+returning exceptional futures. A common example are functions which
+allocate memory and throw <code>std::bad_alloc</code> when running out
+of memory, instead of returning a future. The
+<code>future&lt;&gt; seastar::semaphore::wait()</code> method is one
+such function: It returns a future which may be exceptional if the
+semaphore was <code>broken()</code> or the wait timed out, but may also
+<em>throw</em> an exception when failing to allocate memory it needs to
+hold the list of waiters. Therefore, unless a function — including
+asynchronous functions — is explicitly tagged “<code>noexcept</code>”,
+the application should be prepared to handle exceptions thrown from it.
+In modern C++, code usually uses RAII to be exception-safe without
+sprinkling it with <code>try</code>/<code>catch</code>.
+<code>seastar::defer()</code> is a RAII-based idiom that ensures that
+some cleanup code is run even if an exception is thrown.</p>
+</blockquote>
+<p>Seastar has a convenient generic function,
+<code>futurize_invoke()</code>, which can be useful here.
+<code>futurize_invoke(func, args...)</code> runs a function which may
+return either a future value or an immediate value, and in both cases
+convert the result into a future value. <code>futurize_invoke()</code>
+also converts an immediate exception thrown by the function, if any,
+into a failed future, just like we did above. So using
+<code>futurize_invoke()</code> we can make the above example work even
+if <code>fail()</code> did throw exceptions:</p>

+<p>Here, the lambda function of the first continuation does throw an
+exception instead of returning a failed future. However, we do
+<em>not</em> have the same problem as before, which only happened
+because an asynchronous function threw an exception <em>before</em>
+returning a valid future. Here, <code>f()</code> does return a valid
+future immediately - the failure will only be known later, after
+<code>sleep()</code> resolves. The message in <code>finally()</code>
+will be printed. The methods which attach continuations (such as
+<code>then()</code> and <code>finally()</code>) run the continuation the
+same way, so continuation functions may return immediate values or, in
+this case, throw an immediate exception, and still work properly.</p>
+<h1 data-number="8" id="lifetime-management"><span class="header-section-number">8</span> Lifetime management</h1>
+<p>An asynchronous function starts an operation which may continue long
+after the function returns: The function itself returns a
+<code>future&lt;T&gt;</code> almost immediately, but it may take a while
+until this future is resolved.</p>
+<p>When such an asynchronous operation needs to operate on existing
+objects, or to use temporary objects, we need to worry about the
+<em>lifetime</em> of these objects: We need to ensure that these objects
+do not get destroyed before the asynchronous function completes (or it
+will try to use the freed object and malfunction or crash), and to also
+ensure that the object finally get destroyed when it is no longer needed
+(otherwise we will have a memory leak). Seastar offers a variety of
+mechanisms for safely and efficiently keeping objects alive for the
+right duration. In this section we will explore these mechanisms, and
+when to use each mechanism.</p>
+<h2 data-number="8.1" id="passing-ownership-to-continuation"><span class="header-section-number">8.1</span> Passing ownership to
+continuation</h2>
+<p>The most straightforward way to ensure that an object is alive when a
+continuation runs and is destroyed afterwards is to pass its ownership
+to the continuation. When continuation <em>owns</em> the object, the
+object will be kept until the continuation runs, and will be destroyed
+as soon as the continuation is not needed (i.e., it may have run, or
+skipped in case of exception and <code>then()</code> continuation).</p>
+<p>We already saw above that the way for a continuation to get ownership
+of an object is through <em>capturing</em>:</p>

+<p>Here the continuation captures the value of <code>i</code>. In other
+words, the continuation includes a copy of <code>i</code>. When the
+continuation runs 10ms later, it will have access to this value, and as
+soon as the continuation finishes its object is destroyed, together with
+its captured copy of <code>i</code>. The continuation owns this copy of
+<code>i</code>.</p>
+<p>Capturing by value as we did here - making a copy of the object we
+need in the continuation - is useful mainly for very small objects such
+as the integer in the previous example. Other objects are expensive to
+copy, or sometimes even cannot be copied. For example, the following is

+- it was anyway passed to the function by value and will not be used
+again after capturing it into the continuation, as right after the

+<p>Now, instead of copying the object <code>v</code> into the
+continuation, it is <em>moved</em> into the continuation. The
+C++11-introduced move constructor moves the vector’s data into the
+continuation and clears the original vector. Moving is a quick operation
+- for a vector it only requires copying a few small fields such as the
+pointer to the data. As before, once the continuation is dismissed the
+vector is destroyed - and its data array (which was moved in the move
+operation) is finally freed.</p>
+<p>TODO: talk about temporary_buffer as an example of an object designed
+to be moved in this way.</p>
+<p>In some cases, moving the object is undesirable. For example, some
+code keeps references to an object or one of its fields and the
+references become invalid if the object is moved. In some complex
+objects, even the move constructor is slow. For these cases, C++
+provides the useful wrapper <code>std::unique_ptr&lt;T&gt;</code>. A
+<code>unique_ptr&lt;T&gt;</code> object owns an object of type
+<code>T</code> allocated on the heap. When a
+<code>unique_ptr&lt;T&gt;</code> is moved, the object of type T is not
+touched at all - just the pointer to it is moved. An example of using
+<code>std::unique_ptr&lt;T&gt;</code> in capture is:</p>

+<p><code>std::unique_ptr&lt;T&gt;</code> is the standard C++ mechanism

+cannot be copied: If we try to capture p by value, not by move, we will

+<p>The technique we described above - giving the continuation ownership

+becomes hard and verbose to use. When an asynchronous operation involves
+not just one continuation but a chain of continuations that each needs
+to work on the same object, we need to pass the ownership of the object
+between each successive continuation, which can become inconvenient. It

+<p>This complexity arises because we wanted asynchronous functions and

+<p>This approach raises a question: The caller of <code>slow_op</code>
+is now responsible for keeping the object <code>o</code> alive while the
+asynchronous code started by <code>slow_op</code> needs this object. But
+how will this caller know how long this object is actually needed by the
+asynchronous operation it started?</p>
+<p>The most reasonable answer is that an asynchronous function may need
+access to its parameters until the future it returns is resolved - at
+which point the asynchronous code completes and no longer needs access
+to its parameters. We therefore recommend that Seastar code adopt the
+following convention:</p>
+<blockquote>
+<p><strong>Whenever an asynchronous function takes a parameter by
+reference, the caller must ensure that the referred object lives until
+the future returned by the function is resolved.</strong></p>
+</blockquote>
+<p>Note that this is merely a convention suggested by Seastar, and
+unfortunately nothing in the C++ language enforces it. C++ programmers
+in non-Seastar programs often pass large objects to functions as a const
+reference just to avoid a slow copy, and assume that the called function
+will <em>not</em> save this reference anywhere. But in Seastar code,
+that is a dangerous practice because even if the asynchronous function
+did not intend to save the reference anywhere, it may end up doing it
+implicitly by passing this reference to another function and eventually
+capturing it in a continuation.</p>
+<blockquote>
+<p>It would be nice if future versions of C++ could help us catch
+incorrect uses of references. Perhaps we could have a tag for a special
+kind of reference, an “immediate reference” which a function can use use
+immediately (i.e, before returning a future), but cannot be captured
+into a continuation.</p>
+</blockquote>
+<p>With this convention in place, it is easy to write complex
+asynchronous functions functions like <code>slow_op</code> which pass
+the object around, by reference, until the asynchronous operation is
+done. But how does the caller ensure that the object lives until the
+returned future is resolved? The following is <em>wrong</em>:</p>

+call inside <code>do_with</code> must not use the objects held by
+<code>do_with</code> <em>after</em> the returned future is resolved. It
+is a serious use-after-free bug for an asynchronous function to return a
+future which resolves while still having background operations using the
+<code>do_with()</code>ed objects.</p>
+<p>In general, it is rarely a good idea for an asynchronous function to
+resolve while leaving behind background operations - even if those
+operations do not use the <code>do_with()</code>ed objects. Background
+operations that we do not wait for may cause us to run out of memory (if
+we don’t limit their number) and make it difficult to shut down the
+application cleanly.</p>
+<h2 data-number="8.3" id="sharing-ownership-reference-counting"><span class="header-section-number">8.3</span> Sharing ownership (reference
+counting)</h2>
+<p>In the beginning of this chapter, we already noted that capturing a
+copy of an object into a continuation is the simplest way to ensure that
+the object is alive when the continuation runs and destroyed afterwards.
+However, complex objects are often expensive (in time and memory) to
+copy. Some objects cannot be copied at all, or are read-write and the
+continuation should modify the original object, not a new copy. The
+solution to all these issues are <strong>reference counted</strong>,
+a.k.a. <strong>shared</strong> objects:</p>
+<p>A simple example of a reference-counted object in Seastar is a
+<code>seastar::file</code>, an object holding an open file object (we
+will introduce <code>seastar::file</code> in a later section). A
+<code>file</code> object can be copied, but copying does not involve
+copying the file descriptor (let alone the file). Instead, both copies
+point to the same open file, and a reference count is increased by 1.
+When a file object is destroyed, the file’s reference count is decreased
+by one, and only when the reference count reaches 0 the underlying file
+is actually closed.</p>
+<p>The fact that <code>file</code> objects can be copied very quickly
+and all copies actually point to the same file, make it very convenient
+to pass them to asynchronous code; For example,</p>

+<span id="cb57-5"><a href="#cb57-5" aria-hidden="true" tabindex="-1"></a><span class="op">}</span></span></code></pre></div>
+<p>Note how calling <code>slow_size</code> is as simple as calling
+<code>slow_size(f)</code>, passing a copy of <code>f</code>, without
+needing to do anything special to ensure that <code>f</code> is only
+destroyed when no longer needed. That simply happens naturally when
+nothing refers to <code>f</code> any more.</p>
+<p>You may wonder why <code>return f.size()</code> in the above example
+is safe: Doesn’t it start an asynchronous operation on <code>f</code>
+(the file’s size may be stored on disk, so not immediately available),
+and <code>f</code> may be immediately destroyed when we return and
+nothing keeps holding a copy of <code>f</code>? If <code>f</code> is
+really the last reference, that is indeed a bug, but there is another
+one: the file is never closed. The assumption that makes the code valid
+is that there is another reference to <code>f</code> that will be used
+to close it. The close member function holds on to the reference count
+of that object, so it continues to live even if nothing else keeps
+holding on to it. Since all futures produced by a file object complete
+before it is closed, all that is needed for correctness is to remember
+to always close files.</p>
+<p>The reference counting has a run-time cost, but it is usually very
+small; It is important to remember that Seastar objects are always used
+by a single CPU only, so the reference-count increment and decrement
+operations are not the slow atomic operations often used for reference
+counting, but just regular CPU-local integer operations. Moreover,
+judicious use of <code>std::move()</code> and the compiler’s optimizer
+can reduce the number of unnecessary back-and-forth increment and
+decrement of the reference count.</p>
+<p>C++11 offers a standard way of creating reference-counted shared
+objects - using the template <code>std::shared_ptr&lt;T&gt;</code>. A
+<code>shared_ptr</code> can be used to wrap any type into a
+reference-counted shared object like <code>seastar::file</code> above.
+However, the standard <code>std::shared_ptr</code> was designed with
+multi-threaded applications in mind so it uses slow atomic
+increment/decrement operations for the reference count which we already
+noted is unnecessary in Seastar. For this reason Seastar offers its own
+single-threaded implementation of this template,
+<code>seastar::shared_ptr&lt;T&gt;</code>. It is similar to
+<code>std::shared_ptr&lt;T&gt;</code> except no atomic operations are
+used.</p>
+<p>Additionally, Seastar also provides an even lower overhead variant of
+<code>shared_ptr</code>: <code>seastar::lw_shared_ptr&lt;T&gt;</code>.
+The full-featured <code>shared_ptr</code> is complicated by the need to
+support polymorphic types correctly (a shared object created of one
+class, and accessed through a pointer to a base class). It makes
+<code>shared_ptr</code> need to add two words to the shared object, and
+two words to each <code>shared_ptr</code> copy. The simplified
+<code>lw_shared_ptr</code> - which does <strong>not</strong> support
+polymorphic types - adds just one word in the object (the reference
+count) and each copy is just one word - just like copying a regular
+pointer. For this reason, the light-weight
+<code>seastar::lw_shared_ptr&lt;T&gt;</code> should be preferred when
+possible (<code>T</code> is not a polymorphic type), otherwise
+<code>seastar::shared_ptr&lt;T&gt;</code>. The slower
+<code>std::shared_ptr&lt;T&gt;</code> should never be used in sharded
+Seastar applications.</p>

+<p>These fibers are not threads - each is just a string of continuations
+- but they share some common requirements with traditional threads. For
+example, we want to avoid one fiber getting starved while a second fiber
+continuously runs its continuations one after another. As another
+example, fibers may want to communicate - e.g., one fiber produces data

+<p><code>parallel_for_each</code> is a powerful tool, as it allows
+spawning many tasks in parallel. It can be a great performance gain, but
+there are also caveats. First of all, too high concurrency may be
+troublesome - the details can be found in chapter <strong>Limiting
+parallelism of loops</strong>.</p>
+<p>To restrict the concurrency of <code>parallel_for_each</code> by an
+integer number, use <code>max_concurrent_for_each</code> that is
+described below. More details about dealing with parallelism can be
+found in chapter <strong>Limiting parallelism of loops</strong>.</p>
+<p>Secondly, take note that the order in which iterations will be
+executed within a <code>parallel_for_each</code> loop is arbitrary - if
+a strict ordering is needed, consider using <code>do_for_each</code>
+instead.</p>
+<p>TODO: map_reduce, as a shortcut (?) for parallel_for_each which needs
+to produce some results (e.g., logical_or of boolean results), so we
+don’t need to create a lw_shared_ptr explicitly (or do_with).</p>
+<p>TODO: See seastar commit “input_stream: Fix possible infinite
+recursion in consume()” for an example on why recursion is a possible,
+but bad, replacement for repeat(). See also my comment on

+<p>This starts three futures - one which sleeps for one second (and

+future which resolves as soon as all three futures resolves, i.e., after
+two seconds. This future also has a value, which we shall explain below,

+<p>Both futures are <code>available()</code> (resolved), but the second
+has <code>failed()</code> (resulted in an exception instead of a value).
+Note how we called <code>ignore_ready_future()</code> on this failed
+future, because silently ignoring a failed future is considered a bug,
+and will result in an “Exceptional future ignored” error message. More
+typically, an application will log the failed future instead of ignoring
+it.</p>
+<p>The above example demonstrate that <code>when_all()</code> is
+inconvenient and verbose to use properly. The results are wrapped in a
+tuple, leading to verbose tuple syntax, and uses ready futures which
+must all be inspected individually for an exception to avoid error
+messages.</p>
+<p>So Seastar also provides an easier to use
+<code>when_all_succeed()</code> function. This function too returns a
+future which resolves when all the given futures have resolved. If all
+of them succeeded, it passes a tuple of the resulting values to
+continuation, without wrapping each of them in a future first.
+Sometimes, it could be tedious to unpack the tuple for consuming the
+resulting values. In that case, <code>then_unpack()</code> can be used
+in place of <code>then()</code>. <code>then_unpack()</code> unpacks the
+returned tuple and passes its elements to the following continuation as
+its parameters. If, however, one or more of the futures failed,
+<code>when_all_succeed()</code> resolves to a failed future, containing
+the exception from one of the failed futures. If more than one of the
+given future failed, one of those will be passed on (it is unspecified
+which one is chosen), and the rest will be silently ignored. For
+example,</p>

+<h1 data-number="13" id="semaphores"><span class="header-section-number">13</span> Semaphores</h1>
+<p>Seastar’s semaphores are the standard computer-science semaphores,
+adapted for futures. A semaphore is a counter into which you can deposit
+units or take them away. Taking units from the counter may wait if not
+enough units are available.</p>
+<h2 data-number="13.1" id="limiting-parallelism-with-semaphores"><span class="header-section-number">13.1</span> Limiting parallelism with
+semaphores</h2>
+<p>The most common use for a semaphore in Seastar is for limiting
+parallelism, i.e., limiting the number of instances of some code which
+can run in parallel. This can be important when each of the parallel
+invocations uses a limited resource (e.g., memory) so letting an
+unlimited number of them run in parallel can exhaust this resource.</p>
+<p>Consider a case where an external source of events (e.g., an incoming
+network request) causes an asynchronous function <code>g()</code> to be
+called. Imagine that we want to limit the number of concurrent
+<code>g()</code> operations to 100. I.e., If g() is started when 100
+other invocations are still ongoing, we want it to delay its real work
+until one of the other invocations has completed. We can do this with a
+semaphore:</p>

+<p>In this example, the semaphore starts with the counter at 100. The
+asynchronous operation <code>slow()</code> is only started when we can
+reduce the counter by one (<code>wait(1)</code>), and when
+<code>slow()</code> is done, either successfully or with exception, the
+counter is increased back by one (<code>signal(1)</code>). This way,
+when 100 operations have already started their work and have not yet
+finished, the 101st operation will wait, until one of the ongoing
+operations finishes and returns a unit to the semaphore. This ensures
+that at each time we have at most 100 concurrent <code>slow()</code>
+operations running in the above code.</p>
+<p>Note how we used a <code>static thread_local</code> semaphore, so
+that all calls to <code>g()</code> from the same shard count towards the
+same limit; As usual, a Seastar application is sharded so this limit is
+separate per shard (CPU thread). This is usually fine, because sharded
+applications consider resources to be separate per shard.</p>
+<p>Luckily, the above code happens to be exception safe:
+<code>limit.wait(1)</code> can throw an exception when it runs out of
+memory (keeping a list of waiters), and in that case the semaphore
+counter is not decreased but the continuations below are not run so it
+is not increased either. <code>limit.wait(1)</code> can also return an
+exceptional future when the semaphore is <em>broken</em> (we’ll discuss
+this later) but in that case the extra <code>signal()</code> call is
+ignored. Finally, <code>slow()</code> may also throw, or return an
+exceptional future, but the <code>finally()</code> ensures the semaphore
+is still increased.</p>
+<p>However, as the application code becomes more complex, it becomes
+harder to ensure that we never forget to call <code>signal()</code>
+after the operation is done, regardless of which code path or exceptions
+happen. As an example of what might go wrong, consider the following
+<em>buggy</em> code snippet, which differs subtly from the above one,
+and also appears, on first sight, to be correct:</p>

+<p>But this version is <strong>not</strong> exception safe: Consider
+what happens if <code>slow()</code> throws an exception before returning
+a future (this is different from <code>slow()</code> returning an
+exceptional future - we discussed this difference in the section about
+exception handling). In this case, we decreased the counter, but the
+<code>finally()</code> will never be reached, and the counter will never
+be increased back. There is a way to fix this code, by replacing the
+call to <code>slow()</code> with
+<code>seastar::futurize_invoke(slow)</code>. But the point we’re trying
+to make here is not how to fix buggy code, but rather that by using the
+separate <code>semaphore::wait()</code> and
+<code>semaphore::signal()</code> functions, you can very easily get
+things wrong.</p>
+<p>For exception safety, in C++ it is generally not recommended to have
+separate resource acquisition and release functions. Instead, C++ offers
+safer mechanisms for acquiring a resource (in this case semaphore units)
+and later releasing it: lambda functions, and RAII (“resource
+acquisition is initialization”):</p>
+<p>The lambda-based solution is a function
+<code>seastar::with_semaphore()</code> which is a shortcut for the code
+in the examples above:</p>

+<p><code>with_semaphore()</code>, like the earlier code snippets, waits
+for the given number of units from the semaphore, then runs the given
+lambda, and when the future returned by the lambda is resolved,
+<code>with_semaphore()</code> returns back the units to the semaphore.
+<code>with_semaphore()</code> returns a future which only resolves after
+all these steps are done.</p>
+<p>The function <code>seastar::get_units()</code> is more general. It
+provides an exception-safe alternative to
+<code>seastar::semaphore</code>’s separate <code>wait()</code> and
+<code>signal()</code> methods, based on C++’s RAII philosophy: The
+function returns an opaque units object, which while held, keeps the
+semaphore’s counter decreased - and as soon as this object is
+destructed, the counter is increased back. With this interface you
+cannot forget to increase the counter, or increase it twice, or increase
+without decreasing: The counter will always be decreased once when the
+units object is created, and if that succeeded, increased when the
+object is destructed. When the units object is moved into a
+continuation, no matter how this continuation ends, when the
+continuation is destructed, the units object is destructed and the units
+are returned to the semaphore’s counter. The above examples, written
+with <code>get_units()</code>, looks like this:</p>

+<p>Note the somewhat convoluted way that <code>get_units()</code> needs
+to be used: The continuations must be nested because we need the
+<code>units</code> object to be moved to the last continuation. If
+<code>slow()</code> returns a future (and does not throw immediately),
+the <code>finally()</code> continuation captures the <code>units</code>
+object until everything is done, but does not run any code.</p>
+<p>Seastar’s programmers should generally avoid using the the
+<code>semaphore::wait()</code> and <code>semaphore::signal()</code>
+functions directly, and always prefer either
+<code>with_semaphore()</code> (when applicable) or
+<code>get_units()</code>.</p>
+<h2 data-number="13.2" id="limiting-resource-use"><span class="header-section-number">13.2</span> Limiting resource use</h2>
+<p>Because semaphores support waiting for any number of units, not just
+1, we can use them for more than simple limiting of the <em>number</em>
+of parallel invocation. For example, consider we have an asynchronous
+function <code>using_lots_of_memory(size_t bytes)</code>, which uses
+<code>bytes</code> bytes of memory, and we want to ensure that not more

+<p>Note how this code differs from the code we saw above for limiting
+the number of parallel invocations of a function <code>g()</code>:</p>
+<ol type="1">
+<li>Here we cannot use a single <code>thread_local</code> semaphore.
+Each call to <code>f()</code> has its loop with parallelism of 100, so
+needs its own semaphore “<code>limit</code>”, kept alive during the loop
+with <code>do_with()</code>.</li>
+<li>Here we do not wait for <code>slow()</code> to complete before
+continuing the loop, i.e., we do not <code>return</code> the future
+chain starting at <code>futurize_invoke(slow)</code>. The loop continues
+to the next iteration when a semaphore unit becomes available, while (in
+our example) 99 other operations might be ongoing in the background and
+we do not wait for them.</li>
+</ol>
+<p>In the examples in this section, we cannot use the
+<code>with_semaphore()</code> shortcut. <code>with_semaphore()</code>
+returns a future which only resolves after the lambda’s returned future
+resolves. But in the above example, the loop needs to know when just the
+semaphore units are available, to start the next iteration — and not
+wait for the previous iteration to complete. We could not achieve that
+with <code>with_semaphore()</code>. But the more general exception-safe
+idiom, <code>seastar::get_units()</code>, can be used in this case, and

+<p>The last <code>finally</code> is what ensures that we wait for the
+last operations to complete: After the <code>repeat</code> loop ends
+(whether successfully or prematurely because of an exception in one of
+the iterations), we do a <code>wait(100)</code> to wait for the
+semaphore to reach its original value 100, meaning that all operations
+that we started have completed. Without this <code>finally</code>, the
+future returned by <code>f()</code> will resolve <em>before</em> all the
+iterations of the loop actually completed (the last 100 may still be
+running).</p>
+<p>In the idiom we saw in the above example, the same semaphore is used
+both for limiting the number of background operations, and later to wait
+for all of them to complete. Sometimes, we want several different loops
+to use the same semaphore to limit their <em>total</em> parallelism. In
+that case we must use a separate mechanism for waiting for the
+completion of the background operations started by the loop. The most
+convenient way to wait for ongoing operations is using a gate, which we
+will describe in detail later. A typical example of a loop whose

+<p>In this code, we use the external semaphore <code>limit</code> to

+complete.</p>
+<p>TODO: also allow <code>get_units()</code> or something similar on a

+<p>TODO: say something about semaphore fairness - if someone is waiting
+for a lot of units and later someone asks for 1 unit, will both wait or
+will the request for 1 unit be satisfied?</p>
+<p>TODO: say something about broken semaphores? (or in later section
+especially about breaking/closing/shutting down/etc?)</p>
+<p>TODO: Have a few paragraphs, or even a section, on additional uses of
+semaphores. One is for mutual exclusion using semaphore(1) - we need to
+explain why although why in Seastar we don’t have multiple threads
+touching the same data, if code is composed of different continuations
+(i.e., a fiber) it can switch to a different fiber in the middle, so if
+data needs to be protected between two continuations, it needs a mutex.
+Another example is something akin to wait_all: we start with a
+semaphore(0), run a known number N of asynchronous functions with
+finally sem.signal(), and from all this return the future sem.wait(N).
+PERHAPS even have a separate section on mutual exclusion, where we begin
+with semaphore(1) but also mention shared_mutex</p>
+<h1 data-number="14" id="pipes"><span class="header-section-number">14</span> Pipes</h1>
+<p>Seastar’s <code>pipe&lt;T&gt;</code> is a mechanism to transfer data
+between two fibers, one producing data, and the other consuming it. It
+has a fixed-size buffer to ensures a balanced execution of the two
+fibers, because the producer fiber blocks when it writes to a full pipe,
+until the consumer fiber gets to run and read from the pipe.</p>
+<p>A <code>pipe&lt;T&gt;</code> resembles a Unix pipe, in that it has a
+read side, a write side, and a fixed-sized buffer between them, and
+supports either end to be closed independently (and EOF or broken pipe
+when using the other side). A <code>pipe&lt;T&gt;</code> object holds
+the reader and write sides of the pipe as two separate objects. These
+objects can be moved into two different fibers. Importantly, if one of
+the pipe ends is destroyed (i.e., the continuations capturing it end),
+the other end of the pipe will stop blocking, so the other fiber will
+not hang.</p>
+<p>The pipe’s read and write interfaces are future-based blocking. I.e.,
+the write() and read() methods return a future which is fulfilled when
+the operation is complete. The pipe is single-reader single-writer,
+meaning that until the future returned by read() is fulfilled, read()
+must not be called again (and same for write). Note: The pipe reader and
+writer are movable, but <em>not</em> copyable. It is often convenient to
+wrap each end in a shared pointer, so it can be copied (e.g., used in an
+std::function which needs to be copyable) or easily captured into
+multiple continuations.</p>
+<h1 data-number="15" id="shutting-down-a-service-with-a-gate"><span class="header-section-number">15</span> Shutting down a service with a
+gate</h1>
+<p>Consider an application which has some long operation
+<code>slow()</code>, and many such operations may be started at any
+time. A number of <code>slow()</code> operations may even even be active
+in parallel. Now, you want to shut down this service, but want to make
+sure that before that, all outstanding operations are completed.
+Moreover, you don’t want to allow new <code>slow()</code> operations to
+start while the shut-down is in progress.</p>
+<p>This is the purpose of a <code>seastar::gate</code>. A gate
+<code>g</code> maintains an internal counter of operations in progress.
+We call <code>g.enter()</code> when entering an operation (i.e., before
+running <code>slow()</code>), and call <code>g.leave()</code> when
+leaving the operation (when a call to <code>slow()</code> completed).
+The method <code>g.close()</code> <em>closes the gate</em>, which means
+it forbids any further calls to <code>g.enter()</code> (such attempts
+will generate an exception); Moreover <code>g.close()</code> returns a
+future which resolves when all the existing operations have completed.
+In other words, when <code>g.close()</code> resolves, we know that no
+more invocations of <code>slow()</code> can be in progress - because the
+ones that already started have completed, and new ones could not have
+started.</p>

+<p>In this example, we have a function
+<code>future&lt;&gt; slow()</code> taking 10 seconds to complete. We run
+it in a loop 5 times, waiting 1 second between calls, and surround each
+call with entering and leaving the gate (using <code>with_gate</code>).
+After the 5th call, while all calls are still ongoing (because each
+takes 10 seconds to complete), we close the gate and wait for it before
+exiting the program. We also test that new calls cannot begin after
+closing the gate, by trying to enter the gate again one second after
+closing it.</p>
+<p>The output of this program looks like this:</p>
+<pre><code>starting 1
+starting 2
+starting 3
+starting 4
+starting 5
+WARNING: exceptional future ignored of type &#39;seastar::gate_closed_exception&#39;: gate closed
+done 1
+done 2
+done 3
+done 4
+done 5</code></pre>
+<p>Here, the invocations of <code>slow()</code> were started at 1 second
+intervals. After the “<code>starting 5</code>” message, we closed the
+gate and another attempt to use it resulted in a
+<code>seastar::gate_closed_exception</code>, which we ignored and hence
+this message. At this point the application waits for the future
+returned by <code>g.close()</code>. This will happen once all the
+<code>slow()</code> invocations have completed: Immediately after
+printing “<code>done 5</code>”, the test program stops.</p>
+<p>As explained so far, a gate can prevent new invocations of an
+operation, and wait for any in-progress operations to complete. However,
+these in-progress operations may take a very long time to complete.
+Often, a long operation would like to know that a shut-down has been
+requested, so it could stop its work prematurely. An operation can check
+whether its gate was closed by calling the gate’s <code>check()</code>
+method: If the gate is already closed, the <code>check()</code> method
+throws an exception (the same
+<code>seastar::gate_closed_exception</code> that <code>enter()</code>
+would throw at that point). The intent is that the exception will cause
+the operation calling it to stop at this point.</p>
+<p>In the previous example code, we had an un-interruptible operation
+<code>slow()</code> which slept for 10 seconds. Let’s replace it by a
+loop of 10 one-second sleeps, calling <code>g.check()</code> each
+second:</p>

+<p>For optimal performance, Seastar’s network stack is sharded just like
+Seastar applications are: each shard (thread) takes responsibility for a
+different subset of the connections. Each incoming connection is
+directed to one of the threads, and after a connection is established,
+it continues to be handled on the same thread.</p>
+<p>In the examples we saw earlier, <code>main()</code> ran our function
+<code>f()</code> only once, on the first thread. Unless the server is
+run with the <code>&quot;-c1&quot;</code> option (one thread only), this will mean
+that any connection arriving to a different thread will not be handled.
+So in all the examples below, we will need to run the same service loop
+on all cores. We can easily do this with the <code>smp::submit_to</code>
+function:</p>

+<p>This code works as follows:</p>
+<ol type="1">
+<li>The <code>listen()</code> call creates a <code>server_socket</code>
+object, <code>listener</code>, which listens on TCP port 1234 (on any
+network interface).</li>
+<li>We use <code>do_with()</code> to ensure that the listener socket
+lives throughout the loop.</li>
+<li>To handle one connection, we call <code>listener</code>’s
+<code>accept()</code> method. This method returns a
+<code>future&lt;accept_result&gt;</code>, i.e., is eventually resolved
+with an incoming TCP connection from a client
+(<code>accept_result.connection</code>) and the client’s IP address and
+port (<code>accept_result.remote_address</code>).</li>
+<li>To repeatedly accept new connections, we use the
+<code>keep_doing()</code> loop idiom. <code>keep_doing()</code> runs its
+lambda parameter over and over, starting the next iteration as soon as
+the future returned by the previous iteration completes. The iterations
+only stop if an exception is encountered. The future returned by
+<code>keep_doing()</code> itself completes only when the iteration stops
+(i.e., only on exception).</li>
+</ol>
+<p>Output from this server looks like the following example:</p>
+<pre><code>$ ./a.out
+Accepted connection from 127.0.0.1:47578
+Accepted connection from 127.0.0.1:47582
+...</code></pre>
+<p>If you run the above example server immediately after killing the
+previous server, it often fails to start again, complaining that:</p>
+<pre><code>$ ./a.out
+program failed with uncaught exception: bind: Address already in use</code></pre>
+<p>This happens because by default, Seastar refuses to reuse the local
+port if there are any vestiges of old connections using that port. In
+our silly server, because the server is the side which first closes the
+connection, each connection lingers for a while in the
+“<code>TIME_WAIT</code>” state after being closed, and these prevent
+<code>listen()</code> on the same port from succeeding. Luckily, we can
+give listen an option to work despite these remaining
+<code>TIME_WAIT</code>. This option is analogous to
+<code>socket(7)</code>’s <code>SO_REUSEADDR</code> option:</p>
+<div class="sourceCode" id="cb92"><pre class="sourceCode cpp"><code class="sourceCode cpp"><span id="cb92-1"><a href="#cb92-1" aria-hidden="true" tabindex="-1"></a>    seastar<span class="op">::</span>listen_options lo<span class="op">;</span></span>

+<p>Most servers will always turn on this <code>reuse_address</code>
+listen option. Stevens’ book “Unix Network Programming” even says that
+“All TCP servers should specify this socket option to allow the server
+to be restarted”. Therefore in the future Seastar should probably

+<p>The new part of this code begins by taking the
+<code>connected_socket</code>’s <code>output()</code>, which returns an
+<code>output_stream&lt;char&gt;</code> object. On this output stream
+<code>out</code> we can write our response using the
+<code>write()</code> method. The simple-looking <code>write()</code>
+operation is in fact a complex asynchronous operation behind the scenes,
+possibly causing multiple packets to be sent, retransmitted, etc., as
+needed. <code>write()</code> returns a future saying when it is ok to
+<code>write()</code> again to this output stream; This does not
+necessarily guarantee that the remote peer received all the data we sent
+it, but it guarantees that the output stream has enough buffer space (or
+in the TCP case, there is enough room in the TCP congestion window) to
+allow another write to begin.</p>
+<p>After <code>write()</code>ing the response to <code>out</code>, the
+example code calls <code>out.close()</code> and waits for the future it
+returns. This is necessary, because <code>write()</code> attempts to
+batch writes so might not have yet written anything to the TCP stack at
+this point, and only when close() concludes can we be sure that all the
+data we wrote to the output stream has actually reached the TCP stack —
+and only at this point we may finally dispose of the <code>out</code>
+and <code>s</code> objects.</p>
+<p>Indeed, this server returns the expected response:</p>
+<pre><code>$ telnet localhost 1234
+...
+Seastar is the future!
+Connection closed by foreign host.</code></pre>
+<p>In the above example we only saw writing to the socket. Real servers
+will also want to read from the socket. The
+<code>connected_socket</code>’s <code>input()</code> method returns an
+<code>input_stream&lt;char&gt;</code> object which can be used to read
+from the socket. The simplest way to read from this stream is using the
+<code>read()</code> method which returns a future
+<code>temporary_buffer&lt;char&gt;</code>, containing some more bytes
+read from the socket — or an empty buffer when the remote end shut down
+the connection.</p>
+<p><code>temporary_buffer&lt;char&gt;</code> is a convenient and safe
+way to pass around byte buffers that are only needed temporarily (e.g.,
+while processing a request). As soon as this object goes out of scope
+(by normal return, or exception), the memory it holds gets automatically
+freed. Ownership of buffer can also be transferred by
+<code>std::move()</code>ing it. We’ll discuss
+<code>temporary_buffer</code> in more details in a later section.</p>
+<p>Let’s look at a simple example server involving both reads an writes.
+This is a simple echo server, as described in RFC 862: The server
+listens for connections from the client, and once a connection is
+established, any data received is simply sent back - until the client
+closes the connection.</p>

+<p>The main function <code>service_loop()</code> loops accepting new
+connections, and for each connection calls
+<code>handle_connection()</code> to handle this connection. Our
+<code>handle_connection()</code> returns a future saying when handling
+this connection completed, but importantly, we do
+<strong><em>not</em></strong> wait for this future: Remember that
+<code>keep_doing</code> will only start the next iteration when the
+future returned by the previous iteration is resolved. Because we want
+to allow parallel ongoing connections, we don’t want the next
+<code>accept()</code> to wait until the previously accepted connection
+was closed. So we call <code>handle_connection()</code> to start the
+handling of the connection, but return nothing from the continuation,
+which resolves that future immediately, so <code>keep_doing</code> will
+continue to the next <code>accept()</code>.</p>
+<p>This demonstrates how easy it is to run parallel <em>fibers</em>
+(chains of continuations) in Seastar - When a continuation runs an
+asynchronous function but ignores the future it returns, the
+asynchronous operation continues in parallel, but never waited for.</p>
+<p>It is often a mistake to silently ignore an exception, so if the
+future we’re ignoring might resolve with an except, it is recommended to
+handle this case, e.g. using a <code>handle_exception()</code>
+continuation. In our case, a failed connection is fine (e.g., the client
+might close its connection will we’re sending it output), so we did not
+bother to handle the exception.</p>
+<p>The <code>handle_connection()</code> function itself is
+straightforward — it repeatedly calls <code>read()</code> read on the
+input stream, to receive a <code>temporary_buffer</code> with some data,
+and then moves this temporary buffer into a <code>write()</code> call on
+the output stream. The buffer will eventually be freed, automatically,
+when the <code>write()</code> is done with it. When <code>read()</code>
+eventually returns an empty buffer signifying the end of input, we stop
+<code>repeat</code>’s iteration by returning a
+<code>stop_iteration::yes</code>.</p>
+<h1 data-number="19" id="sharded-services"><span class="header-section-number">19</span> Sharded services</h1>
+<p>In the previous section we saw that a Seastar application usually
+needs to run its code on all available CPU cores. We saw that the
+<code>seastar::smp::submit_to()</code> function allows the main
+function, which initially runs only on the first core, to start the
+server’s code on all <code>seastar::smp::count</code> cores.</p>
+<p>However, usually one needs not just to run code on each core, but
+also to have an object that contains the state of this code.
+Additionally, one may like to interact with those different objects, and
+also have a mechanism to stop the service running on the different
+cores.</p>
+<p>The <code>seastar::sharded&lt;T&gt;</code> template provides a
+structured way create such a <em>sharded service</em>. It creates a
+separate object of type <code>T</code> in each core, and provides
+mechanisms to interact with those copies, to start some code on each,
+and finally to cleanly stop the service.</p>
+<p>To use <code>seastar::sharded</code>, first create a class for the
+object holding the state of the service on a single core. For
+example:</p>

+<p>The <code>s.start()</code> starts the service by creating a
+<code>my_service</code> object on each of the cores. The arguments to
+<code>s.start()</code>, if any (in this example,
+<code>std::string(&quot;hello&quot;)</code>), are passed to
+<code>my_service</code>’s constructor.</p>
+<p>But <code>s.start()</code> did not start running any code yet
+(besides the object’s constructor). For that, we have the
+<code>s.invoke_on_all()</code> which runs the given lambda on all the
+cores - giving each lambda the local <code>my_service</code> object on
+that core. In this example, we have a <code>run()</code> method on each
+object, so we run that.</p>
+<p>Finally, at the end of the run we want to give the service on all
+cores a chance to shut down cleanly, so we call <code>s.stop()</code>.
+This will call the <code>stop()</code> method on each core’s object, and
+wait for all of them to finish. Calling <code>s.stop()</code> before
+destroying <code>s</code> is mandatory - Seastar will warn you if you
+forget to do it.</p>
+<p>In addition to <code>invoke_on_all()</code> which runs the same code
+on all shards, another feature a sharded service often needs is for one
+shard to invoke code another specific shard. This is done by calling the
+sharded service’s <code>invoke_on()</code> method. For example:</p>

+<p>All Seastar applications accept a standard set of command-line
+arguments, such as those we’ve already seen above: The <code>-c</code>
+option for controlling the number of threads used, or <code>-m</code>
+for determining the amount of memory given to the application.</p>
+<p>TODO: list and explain more of these options.</p>
+<p>Every Seastar application also accepts the <code>-h</code> (or
+<code>--help</code>) option, which lists and explains all the available
+options — the standard Seastar ones, and the user-defined ones as
+explained below.</p>
+<h2 data-number="21.2" id="user-defined-command-line-options"><span class="header-section-number">21.2</span> User-defined command-line
+options</h2>
+<p>Seastar parses the command line options (<code>argv[]</code>) when it
+is passed to <code>app_template::run()</code>, looking for its own
+standard options. Therefore, it is not recommended that the application
+tries to parse <code>argv[]</code> on its own because the application
+might not understand some of the standard Seastar options and not be
+able to correctly skip them.</p>
+<p>Rather, applications which want to have command-line options of their
+own should tell Seastar’s command line parser of these additional
+application-specific options, and ask Seastar’s command line parser to
+recognize them too. Seastar’s command line parser is actually the Boost
+library’s <code>boost::program_options</code>. An application adds its
+own option by using the <code>add_options()</code> and
+<code>add_positional_options()</code> methods on the
+<code>app_template</code> to define options, and later calling
+<code>configuration()</code> to retrieve the setting of these options.

+<p>In this example, we add via <code>add_options()</code> two
+application-specific options: <code>--flag</code> is an optional
+parameter which doesn’t take any additional arguments, and
+<code>--size</code> (or <code>-s</code>) takes an integer value, which
+defaults (if this option is missing) to 100. Additionally, we ask via
+<code>add_positional_options()</code> that an unlimited number of
+arguments that do not begin with a “<code>-</code>” — the so-called
+<em>positional</em> arguments — be collected to a vector of strings
+under the “filename” option. Some example outputs from this program:</p>
+<pre><code>$ ./a.out
+Size is 100
+$ ./a.out --flag
+Flag is on
+Size is 100
+$ ./a.out --flag -s 3
+Flag is on
+Size is 3
+$ ./a.out --size 3 hello hi
+Size is 3
+hello
+hi
+$ ./a.out --filename hello --size 3 hi
+Size is 3
+hello
+hi</code></pre>

+<p>This message says that an exceptional future was ignored, and that
+the type of the exception was “<code>myexception</code>”. The type of
+the exception is usually not enough to pinpoint where the problem
+happened, so the warning message also includes the backtrace - the call
+chain - leading to where the exceptional future was destroyed. The
+backtrace is given as a list of addresses, where code in other shared
+libraries is written as a shared library plus offset (when ASLR is
+enabled, the shared libraries are mapped in a different address each
+time).</p>
+<p>Seastar includes a utility, <code>seastar-addr2line</code>, for
+translating these addresses into readable backtraces including exact
+method names, source files and line numbers. This utility needs the
+<em>unstripped</em> executable. Typically, a stripped executable is used
+for production, but an unstripped copy is kept separately to be used in
+debugging - including <code>seastar-addr2line</code>.</p>
+<p>To decode the backtrace, we run</p>
+<pre><code>seastar-addr2line -e a.out</code></pre>
+<p>And then paste the list of addresses in the warning message, and
+conclude with a <code>control-D</code> (it’s also possible, if you want,
+to put the list of addresses in the <code>seastar-addr2line</code>
+command line). The result looks like this:</p>

+<p>Most of the lines at the bottom of this backtrace are not

+<p>Here we see that the warning message was printed by the
+<code>seastar::report_failed_future()</code> function which was called
+when destroying a future (<code>future&lt;&gt;::~future</code>) that had
+not been handled. The future’s destructor was called in line 11 of our
+test code (<code>26.cc</code>), which is indeed the line where we called
+<code>g()</code> and ignored its result. This backtrace gives us an
+accurate understanding of where our code destroyed an exceptional future
+without handling it first, which is usually helpful in solving these
+kinds of bugs. Note that this technique does not tell us where the
+exception was first created, nor what code passed around the exceptional
+future before it was destroyed - we just learn where the future was
+destroyed. To learn where the exception was originally thrown, see the
+next section:</p>
+<h2 data-number="22.2" id="finding-where-an-exception-was-thrown"><span class="header-section-number">22.2</span> Finding where an exception was
+thrown</h2>
+<p>Sometimes an application logs an exception, and we want to know where
+in the code the exception was originally thrown. Unlike languages like
+Java, C++ does not have a builtin method of attaching a backtrace to
+every exception. So Seastar provides functions which allow adding to an
+exception the backtrace recorded when throwing it.</p>
+<p>For example, in the following code we throw and catch an
+<code>std::runtime_error</code> normally:</p>

+<p>The output is</p>
+<pre><code>Exception: std::runtime_error (hello)</code></pre>
+<p>From this output, we have no way of knowing that the exception was
+thrown in <code>g()</code>. We can solve this if we use
+<code>make_exception_future_with_backtrace</code> instead of
+<code>make_exception_future</code>:</p>
+<pre><code>#include &lt;util/backtrace.hh&gt;
+seastar::future&lt;&gt; g() {
+    return seastar::make_exception_future_with_backtrace&lt;&gt;(std::runtime_error(&quot;hello&quot;));
+}</code></pre>
+<p>Now the output looks like</p>
+<pre><code>Exception: seastar::internal::backtraced&lt;std::runtime_error&gt; (hello Backtrace:   0x678bd3
+  0x677204
+  0x67736b

+  0x4f923c
+  0x4f9c38
+  0x4ff4d0
+...
+)</code></pre>
+<p>Which, as above, can be converted to a human-readable backtrace by
+using the <code>seastar-addr2line</code> script.</p>
+<p>In addition to
+<code>seastar::make_exception_future_with_backtrace()</code>, Seastar
+also provides a function <code>throw_with_backtrace()</code>, to throw
+an exception instead of returning an exceptional future. For
+example:</p>
+<pre><code>    seastar::throw_with_backtrace&lt;std::runtime_error&gt;(&quot;hello&quot;);</code></pre>
+<p>In the current implementation, both
+<code>make_exception_future_with_backtrace</code> and
+<code>throw_with_backtrace</code> require that the original exception
+type (in the above example, <code>std::runtime_error</code>) is a
+subclass of the <code>std::exception</code> class. The original
+exception provides a <code>what()</code> string, and the wrapped
+exception adds the backtrace to this string, as demonstrated above.
+Moreover, the wrapped exception type is a <em>subclass</em> of the
+original exception type, which allows <code>catch(...)</code> code to
+continue filtering by the exception original type - despite the addition
+of the backtrace.</p>

+<p>The most basic building block for writing promises is the
+<strong>promise object</strong>, an object of type
+<code>promise&lt;T&gt;</code>. A <code>promise&lt;T&gt;</code> has a
+method <code>future&lt;T&gt; get_future()</code> to returns a future,
+and a method <code>set_value(T)</code>, to resolve this future. An
+asynchronous function can create a promise object, return its future,
+and the <code>set_value</code> method to be eventually called - which
+will finally resolve the future it returned.</p>
+<p>In the following example we create a promise that manages the process
+of printing 10 messages, once every second. We start by creating an
+empty promise to work with. We then spin up a
+<code>seastart::thread</code> to perform the work we want. When the
+work, printing those messages, is completed we call
+<code>promise::set_value</code> to mark the completion of the task.
+Other than that we wait for the future which is generated by our
+promise, just like any other future.</p>

+<h1 data-number="24" id="memory-allocation-in-seastar"><span class="header-section-number">24</span> Memory allocation in
+Seastar</h1>
+<h2 data-number="24.1" id="per-thread-memory-allocation"><span class="header-section-number">24.1</span> Per-thread memory
+allocation</h2>
+<p>Seastar requires that applications be sharded, i.e., that code
+running on different threads operate on different objects in memory. We
+already saw in <a href="#seastar-memory">Seastar memory</a> how Seastar
+takes over a given amount of memory (often, most of the machine’s
+memory) and divides it equally between the different threads. Modern
+multi-socket machines have non-uniform memory access (NUMA), meaning
+that some parts of memory are closer to some of the cores, and Seastar
+takes this knowledge into account when dividing the memory between
+threads. Currently, the division of memory between threads is static,
+and equal - the threads are expected to experience roughly equal amount
+of load and require roughly equal amounts of memory.</p>
+<p>To achieve this per-thread allocation, Seastar redefines the C
+library functions <code>malloc()</code>, <code>free()</code>, and their
+numerous relatives — <code>calloc()</code>, <code>realloc()</code>,
+<code>posix_memalign()</code>, <code>memalign()</code>,
+<code>malloc_usable_size()</code>, and <code>malloc_trim()</code>. It
+also redefines the C++ memory allocation functions,
+<code>operator new</code>, <code>operator delete</code>, and all their
+variants (including array versions, the C++14 delete taking a size, and
+the C++17 variants taking required alignment).</p>
+<p>It is important to remember that Seastar’s different threads
+<em>can</em> see memory allocated by other threads, but they are
+nonetheless strongly discouraged from actually doing this. Sharing data
+objects between threads on modern multi-core machines results in stiff
+performance penalties from locks, memory barriers, and cache-line
+bouncing. Rather, Seastar encourages applications to avoid sharing
+objects between threads when possible (by <em>sharding</em> — each
+thread owns a subset of the objects), and when threads do need to
+interact they do so with explicit message passing, with
+<code>submit_to()</code>, as we shall see later.</p>
+<h2 data-number="24.2" id="foreign-pointers"><span class="header-section-number">24.2</span> Foreign pointers</h2>
+<p>An object allocated on one thread will be owned by this thread, and
+eventually should be freed by the same thread. Freeing memory on the
+<em>wrong</em> thread is strongly discouraged, but is currently
+supported (albeit slowly) to support library code beyond Seastar’s
+control. For example, <code>std::exception_ptr</code> allocates memory;
+So if we invoke an asynchronous operation on a remote thread and this
+operation returns an exception, when we free the returned
+<code>std::exception_ptr</code> this will happen on the “wrong” core. So
+Seastar allows it, but inefficiently.</p>
+<p>In most cases objects should spend their entire life on a single
+thread and be used only by this thread. But in some cases we want to
+reassign ownership of an object which started its life on one thread, to
+a different thread. This can be done using a
+<code>seastar::foreign_ptr&lt;&gt;</code>. A pointer, or smart pointer,
+to an object is wrapped in a <code>seastar::foreign_ptr&lt;P&gt;</code>.
+This wrapper can then be moved into code running in a different thread
+(e.g., using <code>submit_to()</code>).</p>
+<p>The most common use-case is a
+<code>seastar::foreign_ptr&lt;std::unique_ptr&lt;T&gt;&gt;</code>. The
+thread receiving this <code>foreign_ptr</code> will get exclusive use of
+the object, and when it destroys this wrapper, it will go back to the
+original thread to destroy the object. Note that the object is not only
+freed on the original shard - it is also <em>destroyed</em> (i.e., its
+destructor is run) there. This is often important when the object’s
+destructor needs to access other state which belongs to the original
+shard - e.g., unlink itself from a container.</p>
+<p>Although <code>foreign_ptr</code> ensures that the object’s
+<em>destructor</em> automatically runs on the object’s home thread, it
+does not absolve the user from worrying where to run the object’s other
+methods. Some simple methods, e.g., methods which just read from the
+object’s fields, can be run on the receiving thread. However, other
+methods may need to access other data owned by the object’s home shard,
+or need to prevent concurrent operations. Even if we’re sure that object
+is now used exclusively by the receiving thread, such methods must still
+be run, explicitly, on the home thread:</p>
+<pre><code>    // fp is some foreign_ptr&lt;&gt;
+    return smp::submit_to(fp.get_owner_shard(), [p=fp.get()]
+        { return p-&gt;some_method(); });</code></pre>
+<p>So <code>seastar::foreign_ptr&lt;&gt;</code> not only has functional
+benefits (namely, to run the destructor on the home shard), it also has
+<em>documentational</em> benefits - it warns the programmer to watch out
+every time the object is used, that this is a <em>foreign</em> pointer,
+and if we want to do anything non-trivial with the pointed object, we
+may need to do it on the home shard.</p>
+<p>Above, we discussed the case of transferring ownership of an object
+to a another shard, via
+<code>seastar::foreign_ptr&lt;std::unique_ptr&lt;T&gt;&gt;</code>.
+However, sometimes the sender does not want to relinquish ownership of
+the object. Sometimes, it wants the remote thread to operate on its
+object and return with the object intact. Sometimes, it wants to send
+the same object to multiple shards. In such cases,
+<code>seastar::foreign_ptr&lt;seastar::lw_shared_ptr&lt;T&gt;&gt;</code>
+is useful. The user needs to watch out, of course, not to operate on the
+same object from multiple threads concurrently. If this cannot be
+ensured by program logic alone, some methods of serialization must be
+used - such as running the operations on the home shard with
+<code>submit_to()</code> as described above.</p>
+<p>Normally, a <code>seastar::foreign_ptr</code> cannot not be copied -
+only moved. However, when it holds a smart pointer that can be copied
+(namely, a <code>shared_ptr</code>), one may want to make an additional
+copy of that pointer and create a second <code>foreign_ptr</code>. Doing
+this is inefficient and asynchronous (it requires communicating with the
+original owner of the object to create the copies), so a method
+<code>future&lt;foreign_ptr&gt; copy()</code> needs to be explicitly
+used instead of the normal copy constructor.</p>

+<p>Seastar’s programming model, using futures and continuations, is very
+powerful and efficient. However, as we’ve already seen in examples
+above, it is also relatively verbose: Every time that we need to wait
+before proceeding with a computation, we need to write another
+continuation. We also need to worry about passing the data between the
+different continuations (using techniques like those described in the <a href="#lifetime-management">Lifetime management</a> section). Simple
+flow-control constructs such as loops also become more involved using
+continuations. For example, consider this simple classical synchronous
+code:</p>

+<code>seastar::thread</code> provides an execution environment where

+<p>A <code>seastar::thread</code> is <strong>not</strong> a separate
+operating system thread. It still uses continuations, which are
+scheduled on Seastar’s single thread (per core). It works as
+follows:</p>
+<p>The <code>seastar::thread</code> allocates a 128KB stack, and runs
+the given function until the it <em>blocks</em> on the call to a
+future’s <code>get()</code> method. Outside a
+<code>seastar::thread</code> context, <code>get()</code> may only be
+called on a future which is already available. But inside a thread,
+calling <code>get()</code> on a future which is not yet available stops
+running the thread function, and schedules a continuation for this
+future, which continues to run the thread’s function (on the same saved
+stack) when the future becomes available.</p>
+<p>Just like normal Seastar continuations, <code>seastar::thread</code>s
+always run on the same core they were launched on. They are also
+cooperative: they are never preempted except when
+<code>seastar::future::get()</code> blocks or on explicit calls to
+<code>seastar::thread::yield()</code>.</p>
+<p>It is worth reiterating that a <code>seastar::thread</code> is not a
+POSIX thread, and it can only block on Seastar futures, not on blocking
+system calls. The above example used <code>seastar::sleep()</code>, not
+the <code>sleep()</code> system call. The <code>seastar::thread</code>’s
+function can throw and catch exceptions normally. Remember that
+<code>get()</code> will throw an exception if the future resolves with
+an exception.</p>
+<p>In addition to <code>seastar::future::get()</code>, we also have
+<code>seastar::future::wait()</code> to wait <em>without</em> fetching
+the future’s result. This can sometimes be useful when you want to avoid
+throwing an exception when the future failed (as <code>get()</code>
+does). For example:</p>

+<p>While <code>seastar::thread</code>s and <code>seastar::async()</code>
+make programming more convenient, they also add overhead beyond that of
+programming directly with continuations. Most notably, each
+<code>seastar::thread</code> requires additional memory for its stack.
+It is therefore not a good idea to use a <code>seastar::thread</code> to
+handle a highly concurrent operation. For example, if you need to handle
+10,000 concurrent requests, do not use a <code>seastar::thread</code> to
+handle each — use futures and continuations. But if you are writing code
+where you know that only a few instances will ever run concurrently,
+e.g., a background cleanup operation in your application,
+<code>seastar::thread</code> is a good match.
+<code>seastar::thread</code> is also great for code which doesn’t care
+about performance — such as test code.</p>
+<h1 data-number="26" id="isolation-of-application-components"><span class="header-section-number">26</span> Isolation of application
+components</h1>
+<p>Seastar makes multi-tasking very easy - as easy as running an
+asynchronous function. It is therefore easy for a server to do many
+unrelated things in parallel. For example, a server might be in the
+process of answering 100 users’ requests, and at the same time also be
+making progress on some long background operation.</p>
+<p>But in the above example, what percentage of the CPU and disk
+throughput will the background operation get? How long can one of the
+user’s requests be delayed by the background operation? Without the
+mechanisms we describe in this section, these questions cannot be
+reliably answered:</p>
+<ul>
+<li>The background operation may be a very “considerate” single fiber,
+i.e., run a very short continuation and then schedule the next
+continuation to run later. At each point the scheduler sees 100
+request-handling continuations and just one of the background
+continuations ready to run. The background task gets around 1% of the
+CPU time, and users’ requests are hardly delayed.</li>
+<li>On the other hand, the background operation may spawn 1,000 fibers
+in parallel and have 1,000 ready-to-run continuations at each time. The
+background operation will get about 90% of the runtime, and the
+continuation handling a user’s request may get stuck behind 1,000 of
+these background continuations, and experience huge latency.</li>
+</ul>
+<p>Complex Seastar applications often have different components which
+run in parallel and have different performance objectives. In the above
+example we saw two components - user requests and the background
+operation. The first goal of the mechanisms we describe in this section
+is to <em>isolate</em> the performance of each component from the
+others; In other words, the throughput and latency of one component
+should not depend on decisions that another component makes - e.g., how
+many continuations it runs in parallel. The second goal is to allow the
+application to <em>control</em> this isolation, e.g., in the above
+example allow the application to explicitly control the amount of CPU
+the background operation receives, so that it completes at a desired
+pace.</p>
+<p>In the above examples we used CPU time as the limited resource that
+the different components need to share effectively. As we show later,
+another important shared resource is disk I/O.</p>

+<p>It turns out that if the two <code>loop()</code> calls had the same
+parallelism <code>1</code>, we get roughly the same amount of work from
+both of them:</p>
+<pre><code>Counters: 3&#39;559&#39;635&#39;758, 3&#39;254&#39;521&#39;376</code></pre>
+<p>But if for example we ran a <code>loop(1)</code> in parallel with a
+<code>loop(10)</code>, the result is that the <code>loop(10)</code> gets
+10 times more work done:</p>
+<pre><code>Counters: 629&#39;482&#39;397, 6&#39;320&#39;167&#39;297</code></pre>
+<p>Why does the amount of work that loop(1) can do in ten seconds
+depends on the parallelism chosen by its competitor, and how can we
+solve this?</p>
+<p>The reason this happens is as follows: When a future resolves and a
+continuation was linked to it, this continuation becomes ready to run.
+By default, Seastar’s scheduler keeps a single list of ready-to-run
+continuations (in each shard, of course), and runs the continuations at
+the same order they became ready to run. In the above example,
+<code>loop(1)</code> always has one ready-to-run continuation, but
+<code>loop(10)</code>, which runs 10 loops in parallel, always has ten
+ready-to-run continuations. So for every continuation of
+<code>loop(1)</code>, Seastar’s default scheduler will run 10
+continuations of <code>loop(10)</code>, which is why loop(10) gets 10
+times more work done.</p>
+<p>To solve this, Seastar allows an application to define separate
+components known as <strong>scheduling groups</strong>, which each has a
+separate list of ready-to-run continuations. Each scheduling group gets
+to run its own continuations on a desired percentage of the CPU time,
+but the number of runnable continuations in one scheduling group does
+not affect the amount of CPU that another scheduling group gets. Let’s
+look at how this is done:</p>
+<p>A scheduling group is defined by a value of type
+<code>scheduling_group</code>. This value is opaque, but internally it
+is a small integer (similar to a process ID in Linux). We use the
+<code>seastar::with_scheduling_group()</code> function to run code in
+the desired scheduling group:</p>

+<p>Here we created two scheduling groups, <code>sg1</code> and
+<code>sg2</code>. Each scheduling group has an arbitrary name (which is
+used for diagnostic purposes only), and a number of <em>shares</em>, a
+number traditionally between 1 and 1000: If one scheduling group has
+twice the number of shares than a second scheduling group, it will get
+twice the amount of CPU time. In this example, we used the same number
+of shares (100) for both groups, so they should get equal CPU time.</p>
+<p>Unlike most objects in Seastar which are separate per shard, Seastar
+wants the identities and numbering of the scheduling groups to be the
+same on all shards, because it is important when invoking tasks on
+remote shards. For this reason, the function to create a scheduling
+group, <code>seastar::create_scheduling_group()</code>, is an
+asynchronous function returning a
+<code>future&lt;scheduling_group&gt;</code>.</p>
+<p>Running the above example, with both scheduling group set up with the
+same number of shares (100), indeed results in both scheduling groups
+getting the same amount of CPU time:</p>
+<pre><code>Counters: 3&#39;353&#39;900&#39;256, 3&#39;350&#39;871&#39;461</code></pre>
+<p>Note how now both loops got the same amount of work done - despite
+one loop having 10 times the parallelism of the second loop.</p>
+<p>If we change the definition of the second scheduling group to have
+200 shares, twice the number of shares of the first scheduling group,
+we’ll see the second scheduling group getting twice the amount of CPU
+time:</p>
+<pre><code>Counters: 2&#39;273&#39;783&#39;385, 4&#39;549&#39;995&#39;716</code></pre>
