The events_waits_history_long table contains the most recent 10,000 wait events. To change the table size, modify the performance_schema_events_waits_history_long_size system variable at server startup. Wait events are not added to the table until they have ended. As new events are added, older events are discarded if the table is full. When a thread ends, its rows are removed from the table.

The events_waits_history_long table has the same structure as events_waits_current. See Section 22.8.4.1, “The events_waits_current Table”.

TRUNCATE TABLE is permitted for the events_waits_history_long table. It removes the rows.

For information about configuration of wait event collection, see Section 22.8.4, “Performance Schema Wait Event Tables”.
