8.2.2. Dynamically Changing innodb_stats_on_metadata

In MySQL 5.5 and higher, you can change the setting of innodb_stats_on_metadata dynamically at runtime, to control whether or not InnoDB performs statistics gathering when metadata statements are executed. To change the setting, issue the statement SET GLOBAL innodb_stats_on_metadata=mode, where mode is either ON or OFF (or 1 or 0). Changing this setting requires the SUPER privilege and immediately affects the operation of all connections.

This setting is related to the feature described in Section 8.5, “Controlling Optimizer Statistics Estimation”.
