25.11.7.2 The events_transactions_history Table

The events_transactions_history table contains the most recent N transaction events per thread. The value of N is autosized at server startup. To set the table size explicitly, set the performance_schema_events_transactions_history_size system variable at server startup. Transaction 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.

The events_transactions_history table has the same structure as events_transactions_current. See Section 25.11.7.1, “The events_transactions_current Table”.

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

For information about configuration of transaction event collection, see Section 25.11.7, “Performance Schema Transaction Tables”.
