The
events_statements_history_long
table contains the N
most recent
statement events that have ended globally, across all threads.
Statement 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 either row.
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.
The
events_statements_history_long
table has the same columns as
events_statements_current
. See
Section 25.12.6.1, “The events_statements_current Table”.
TRUNCATE TABLE
is permitted for
the
events_statements_history_long
table. It removes the rows.
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”.
