The events_stages_history table
contains the most recent 10 stage events per thread. The table
size may be changed by modifying the
performance_schema_events_stages_history_size
system variable at server startup. As new events are added to
the table, older events are discarded if the table is full.
Events are not added to the table until they have ended.
The events_stages_history table
has the same structure as
events_stages_current. See
Section 21.9.4.1, “The events_stages_current Table”.
The events_stages_history table
can be truncated with TRUNCATE
TABLE.
The events_stages_history table
was added in MySQL 5.6.3.
