As of MySQL 8.0.14, the thread pool
        INFORMATION_SCHEMA tables are also available
        as Performance Schema tables. (See
        Performance Schema Thread Pool Tables.) The
        INFORMATION_SCHEMA tables are deprecated;
        expect them to be removed in a future version of MySQL.
        Applications should transition away from the old tables to the
        new tables. For example, if an application uses this query:
      
SELECT * FROM INFORMATION_SCHEMA.TP_THREAD_STATE;The application should use this query instead:
SELECT * FROM performance_schema.tp_thread_state;
      The TP_THREAD_STATE table has one row per
      thread created by the thread pool to handle connections.
    
      For descriptions of the columns in the
      INFORMATION_SCHEMA
      TP_THREAD_STATE table, see
      The tp_thread_state Table. The
      Performance Schema tp_thread_state
      table has equivalent columns.
