With this demo the superior performance of MicroStream and the Java VM compared to JPA with a connected database is visualized. It is a Spring Boot application with a Vaadin frontend. Per default Postgres is used, but you can change the application's setup, to use any other database.
-
First you need to setup a Postgres database. Then the connection settings must be adjusted in the application.properties file accordingly.
-
Start the program via its main class: one.microstream.demo.bookstore.Application
-
At the first start a new MicroStream database is generated with random data. Depending on the setting
bookstoredemo.initialDataAmount
more or less data is produced. -
Then the data has to be migrated to the connected JPA database
-
If
bookstoredemo.jpaDataMigrationStrategy
isbatch_insert
(default), the data will be automatically migrated. -
If it is set to
sql_file
the generated data will be written into a SQL file, which must then be imported into the JPA database. It can be found in the configured data directorybookstoredemo.dataDir
, default is [userhome]/microstream-bookstoredemo. Please note, that this is by far the faster way, but the generated inserts are optimized for Postgres and probably won't work with a different database.
-
Here you can see the entity relationship diagram of the generated database:
After the application has started, open the client interface at: http://localhost.
