table contains the
N most recent
stage events that have ended globally, across all threads.
Stage 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
The Performance Schema autosizes the value of
N during server startup. To set the
table size explicitly, set the
system variable at server startup.
For more information about the relationship between the three stage event tables, see Performance Schema Tables for Current and Historical Events.
For information about configuring whether to collect stage events, see Section 10.5, “Performance Schema Stage Event Tables”.
