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:
SELECT * FROM INFORMATION_SCHEMA.TP_THREAD_GROUP_STATS;
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 27.12.16.2, “The tp_thread_group_stats Table”. The Performance Schema tp_thread_group_stats
table has equivalent columns.
