This is fantastic advice. At the first startup I worked at, we had several issues with our MySQL dbs & ETL jobs (MyISAM table locks, slow updates, no replication) - I spent a few days just reading the relevant sections of "High Performance MySQL: Optimization, Backups, Replication, and More" - and voila I had solid recommendations built on facts rather than random opinions people created over the years - put my career on an entirely different trajectory.
