MySQL 8.0 Reference Manual  /  ...  /  The INFORMATION_SCHEMA TP_THREAD_GROUP_STATS Table



As of MySQL 8.0.14, the thread pool INFORMATION_SCHEMA tables are also available as Performance Schema tables. (See Section 27.12.16, “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:


The application should use this query instead:

SELECT * FROM performance_schema.tp_thread_group_stats;

The TP_THREAD_GROUP_STATS table reports statistics per thread group. There is one row per group.

For descriptions of the columns in the INFORMATION_SCHEMA TP_THREAD_GROUP_STATS table, see Section, “The tp_thread_group_stats Table”. The Performance Schema tp_thread_group_stats table has equivalent columns.
