21.9.3.2. The events_waits_history Table

The events_waits_history table contains the most recent 10 wait events per thread. The table size may be changed by modifying the performance_schema_events_waits_history_size system variable at server startup. As new events are added to the table, older events are discarded if the table is full. Events are not added to the table until they have ended.

The events_waits_history table has the same structure as events_waits_current. See Section 21.9.3.1, "The events_waits_current Table".

The events_waits_history table can be truncated with TRUNCATE TABLE.
