MySQL 9.4 Release Notes
Note
The INFORMATION_SCHEMA thread pool tables are
deprecated, and subject to removal in a future version of MySQL.
You should use the versions available as Performance Schema
tables insted. See
Section 29.12.16, “Performance Schema Thread Pool Tables”.
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_STATE;The application should use this query instead:
SELECT * FROM performance_schema.tp_thread_group_state;
The TP_THREAD_GROUP_STATE table has one row per
thread group in the thread pool. Each row provides information
about the current state of a group.
For descriptions of the columns in the
INFORMATION_SCHEMA
TP_THREAD_GROUP_STATE table, see
Section 29.12.16.2, “The tp_thread_group_state Table”.
The Performance Schema
tp_thread_group_state table has
equivalent columns.
