cond_instances table lists all conditions while the server is executing. A condition, or instrumented condition object, is an internal code mechanism used for signalling that a specific event has occurred so that any threads waiting for this condition can continue.
The maximum number of conditions stored in the performance schema is determined by the performance_schema_max_cond_instances system variable.
||Client user name for the connection, or
||Address in memory of the instrumented condition.|
