MySQL Infrastructure Testing Automation

This feature thread tracks the evolution of automating testing for MySQL infrastructure to ensure reliability and facilitate operations. Initially, the focus was on establishing robust backup and recovery strategies. This post details the implementation of automated backup verification, delayed replicas for safeguard, and a production-like test cluster for continuous failover testing. It also covers the automation of adding new replicas to existing clusters through chat commands. The introduction of Orchestrator further enhances automated master failovers, failure detection, and complex topology management for MySQL clusters across multiple data centers, integrating with chatops for visibility and control.
