Thecond_instances table lists all the conditions seen by the Performance Schema while the server executes. A condition is a synchronization mechanism used in the code to signal that a specific event has happened, so that a thread waiting for this condition can resume work.
When a thread is waiting for something to happen, the condition name is an indication of what the thread is waiting for, but there is no immediate way to tell which other threads cause the condition to happen.
Thecond_instances table has these columns:
NAMEThe instrument name associated with the condition.
OBJECT_INSTANCE_BEGINThe address in memory of the instrumented condition.
TRUNCATE TABLE is not permitted for thecond_instances table.
