Solving MySQL Scalability with Adaptive IO
summary
Cloud SQL for MySQL adds an adaptive purge that throttles background undo cleanup by monitoring redo pressure, an adaptive IO limits controller that adjusts InnoDB IO capacity every second, and an adaptive buffer pool warm-up that scales warm‑up I/O to current user load. Engine-level sharded IO and faster redo recovery let redo grow to 3 GB (≈50% increase), and the combined “optimize write” rollout delivers about 3x higher throughput versus the prior Enterprise Plus baseline.
