Developer, Operations

Performance Schema in MySQL is maturing from version to version. It includes extended lock instrumentation, memory usage statistics, new tables for server variables, first time ever instrumentation for user variables, prepared statements and stored routines.

Version 8.0 adds additional variables, replication, error messages, data locks instrumentation. A lot! Amazing! And complicated!

In this tutorial, we will try all these instruments out. We will provide a test environment and a few typical problems that would be difficult to solve before MySQL 5.7. Just few examples:

- "Where is memory going?"
- "Why are these queries hanging?"
- "How huge is the overhead of my stored procedures?"
- "Why are queries waiting for metadata locks?"

You will not only learn how to collect and use this information but will gain practical experience with it. You will also learn many details on how to setup Performance Schema.
