Mysql

This one takes you from MySQL basics through production administration, covering everything from storage engine selection to setting up replication and failover. You'll work through query optimization with EXPLAIN analysis, learn backup strategies with mysqldump, and get into high availability patterns with Group Replication and ProxySQL. The bonding with a PostgreSQL DBA skill is interesting since you'll often need to know both systems in practice. It's comprehensive enough that you could go from installing MySQL to running it in production, though you'll want some SQL and Linux fundamentals first. The focus on performance tuning and HA makes this more than just a beginner's guide.
