The cond instances Table
The cond_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 thread, or threads, will cause the
condition to happen.
The cond_instances table has these columns:
• NAME
The instrument name associated with the condition.
• OBJECT_INSTANCE_BEGIN
The address in memory of the condition that was instrumented.
