Stage Event Consumers-opracowanie

Stage Event Consumers
These consumers require both global_instrumentation and thread_instrumentation to be
YES or they are not checked.
• events_stages_current, if NO, disables collection of individual stage events in the
events_stages_current table. If YES, it enables stage event collection and the Performance
Schema checks the events_stages_history and events_stages_history_long
consumers.
• events_stages_history is not checked if event_stages_current is NO. Otherwise, a
events_stages_history value of NO or YES disables or enables collection of stage events in the
events_stages_history table.
• events_stages_history_long is not checked if event_stages_current is NO. Otherwise, a
events_stages_history_long value of NO or YES disables or enables collection of stage events
in the events_stages_history_long table.
