Full disclosure I am friends with the author so my review will be biased. Not to mention I am kind of a geek for database performance tuning. But to be honest, this book is meant for the performance tuning geek. As far as I know, there is currently no other book on the market that covers the SQL Server Query Store and definitely not one up-to-date for SQL Server 2019. Tracy not only covers the basics in configuration and management, but also many edge case scenarios. This is a valuable book for any SQL DBA.

Extremely dry. More of a reference book than something you should read front to back. For example it explains every column of Query Store DMVs.
