Derived from #4238.

To provide a better experience in profiling query performance issues, we will need a framework to record and display the execution info of any specific query.

A profiling library has been proposed in #10023, which will record some execution information and display it via EXPLAIN ANALYZE statement.

A system table query_profile has been proposed in #11760, which can be used to query the profile information of specific queries with query id.

Further works:

  • Support recording profile information for queries run in cluster mode
  • Support recording table scan profile information
  • GUI tool for displaying the query profile
