This book is the perfect hands-on reference for any database administrator, backend developer or data engineer working with MySQL in production. It's organised into 75+ practical, task-driven recipes solving the real challenges that practitioners face every day. These include things like installing and hardening a MySQL 9 server, migrating from MySQL 5.7, MongoDB and PostgreSQL, diagnosing deadlocks and startup failures, tuning slow queries with EXPLAIN ANALYZE, configuring InnoDB Cluster for automatic failover, and implementing point-in-time recovery with the binary log and Clone Plugin.

This second edition looks at the most significant new features of MySQL 9, including the VECTOR data type for use with AI and machine learning workloads, the JavaScript Multilingual Engine powered by GraalVM, the updated InnoDB ClusterSet for high availability across multiple data centres, and the structured JSON error log. Every recipe is shown on a consistent, production-realistic sample platform, giving readers the context to apply each technique directly to their own environments. So, whatever you're doing, this cookbook's got you covered. It'll give you all the exact steps, commands, and explanations you need to get the job done.
