table (added in MySQL 5.7.3) contains the most recent
N transaction events. The value of
N is autosized at server startup.
To set the table size explicitly, set the
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. When a
thread ends, its rows are removed from the table.
table has the same structure as
Section 22.214.171.124, “The events_transactions_current Table”.
For information about configuration of transaction event collection, see Section 23.9.7, “Performance Schema Transaction Tables”.
