Statement Event Consumers-opracowanie

Statement Event Consumers
These consumers require both global_instrumentation and thread_instrumentation to be
YES or they are not checked.
• events_statements_current, if NO, disables collection of individual statement
events in the events_statements_current table. If YES, it enables statement event
collection and the Performance Schema checks the events_statements_history and
events_statements_history_long consumers.
• events_statements_history is not checked if events_statements_current is NO.
Otherwise, a events_statements_history value of NO or YES disables or enables collection of
statement events in the events_statements_history table.
• events_statements_history_long is not checked if events_statements_current is
NO. Otherwise, a events_statements_history_long value of NO or YES disables or enables
collection of statement events in the events_statements_history_long table.
