18.104.22.168 The events_statements_history Table
events_statements_history table contains the
N most recent statement events that have ended per thread. Statement events are not added to the table until they have ended. When the table contains the maximum number of rows for a given thread, the oldest thread row is discarded when a new row for that thread is added. When a thread ends, all its rows are discarded.
The Performance Schema autosizes the value of
N during server startup. To set the number of rows per thread explicitly, set the
performance_schema_events_statements_history_size system variable at server startup.
events_statements_history table has the same columns as
events_statements_current. See Section 22.214.171.124, “The events_statements_current Table”.
For more information about the relationship between the three
events_statements_ event tables, see Section 25.9, “Performance Schema Tables for Current and Historical Events”.
For information about configuring whether to collect statement events, see Section 25.12.6, “Performance Schema Statement Event Tables”.
