28.5.2 INFORMATION_SCHEMA TP_THREAD_GROUP_STATE 表
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.
