-The MySQL performance_schema, first available in MySQL 5.5, provides instrumentation for many vital server resources such as memory allocation, stored programs, metadata locking, etc. However, the performance_schema contains more than 80 tables, and getting the necessary information often requires joining tables within the performance_schema, and tables from the information_schema. Building on both performance_schema and information_schema, the sys_schema provides a powerful collection of [user-friendly views](https://dev.mysql.com/doc/refman/5.7/en/sys-schema-views.html) in a read-only database and is fully enabled in Azure Database for MySQL flexible server version 5.7.
