Performance Schema in 10.5 ES¶

MariaDB Enterprise Server uses the Performance Schema to track data useful in troubleshooting performance related issues and events. By default, the Performance Schema is disabled and its tables not updated with current data.

If you want to use the Performance Schema, set the performance_schema system variable and restart the Server:

[mariadb]
performance_schema = ON

When the Server starts back up, it begins using the Performance Schema.
