table contains the most recent 10,000 wait events that have
ended globally, across all threads. Wait events are not added
to the table until they have ended. When the table becomes
full, the oldest row is discarded when a new row is added,
regardless of which thread generated either row.
To change the table size, modify the
system variable at server startup.
For more information about the relationship between the three wait event tables, see Performance Schema Tables for Current and Historical Events.
For information about configuring whether to collect wait events, see Section 10.4, “Performance Schema Wait Event Tables”.
