diff

Show the difference between the two profile results
+ means an increasing count, rows_sent, rows_examined, rows_affected, bytes_sent, and query_time、lock_time are slower
- means a decreasing count, rows_sent, rows_examined, rows_affected, bytes_sent, and query_time、lock_time are faster

- Print no header when TSV and CSV format
--show-footers
- Print the total number of each 1xx ~ 5xx in the footer of the table or Markdown format
--limit=5000
- Maximum number of profile results to be printed
- This setting is to avoid using too much memory
- The default is 5000 lines
-o, --output="simple"
- Specify the profile results to be print, separated by commas
- count, query, min-query-time, max-query-time, sum-query-time, avg-query-time, min-lock-time, max-lock-time, sum-lock-time, avg-lock-time, min-rows-sent, max-rows-sent, sum-rows-sent, avg-rows-sent, min-rows-examined, max-rows-examined, sum-rows-examined, avg-rows-examined, min-rows-affected, max-rows-affected, sum-rows-affected, avg-rows-affected, min-bytes-sent, max-bytes-sent, sum-bytes-sent, avg-bytes-sent
  - These outputs are the same for all
  - pN(1~100)-<sort-key> is modified by the values specified in --percentiles
- The default is simple
- standard outputs all without *-rows-affected and *-bytes-sent
-m, --matching-groups=PATTERN,...
- Treat Queries that match regular expressions as the same Query
- Evaluate in the specified order. If matched, no further evaluation is performed.
-f, --filters=FILTERS
- Filters the targets for profile
- See Filter
--pos=POSITION_FILE
- Stores the number of bytes to which the file has been read.
- If the number of bytes is stored in the POSITION_FILE, the data after that number of bytes will be profiled
- You can profile without truncating the file
  - Also, it is expected to work fast because it seeks and skips files
--nosave-pos
- Data after the number of bytes specified by --pos is profiled, but the number of bytes reads is not stored
--percentiles
- Specifies the percentile values to output, separated by commas
- e.g. 90,95,99
-a, --noabstract
- Do not abstract all numbers to N and strings to 'S'
--bundle-values
- Bundle VALUES of INSERT statement
- See: Usage samples
--bundle-where-in
- Bundle WHERE IN conditions
- See: Usage samples
