24.11.6.3 The events_statements_history_long Table

The events_statements_history_long table contains the most recent N statement events. The value of N is autosized at server startup. To set the table size explicitly, set the performance_schema_events_statements_history_long_size system variable at server startup. Statement 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_statements_history_long table has the same structure as events_statements_current. See Section 24.11.6.1, “The events_statements_current Table”.

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

For information about configuration of statement event collection, see Section 24.11.6, “Performance Schema Statement Event Tables”.
