Of the existing MySQL performance tuning resources, this is the most complete one I've seen. MySQL 8 has been out for a while now, and this book will get you up-to-date on tuning it.

The author starts with a high-level overview of tuning and benchmarking. With 900+ pages to work with, he has taken time to give this theoretical overview, but also highly specific details, with screenshots, diagrams, and terminal output for nearly every concept and tool mentioned.

The second section provides an in-depth tour of sources of information for tuning. This section includes the missing documentation for tools like sys schema and performance schema; I haven't seen depth and detail like this about these tools anywhere else.

Section three is a deep dive into available tools. A lot of performance guides miss the latest Oracle tools for monitoring and tuning, like MySQL Shell and histograms. The author has described them here in detail. However, he didn't forget to include the available open-source tools like ProxySQL.

Finally, in the fourth and fifth sections, the author discusses real-world application of the tools: query analysis, diagnosing lock contention, replication, etc.

This would be a regularly accessed guide on any DBA's bookshelf.
