We run 840+ Redis 7.2.12 instances on AWS EKS serving ~1.64M operations per second. Facing a performance ceiling, fragmented client tooling, and a licensing dead-end after Redis left BSD, we migrated the entire fleet to Valkey 8.1.5 — with zero application code changes and sub-five-minute rollback.
This talk is an evidence-first walkthrough. We'll cover what actually changed under the hood (production-ready I/O threading, Swiss Table memory layout, deterministic cluster failover) versus what stayed identical (wire protocol, data format, client libraries) — the distinction that made a fleet-wide engine swap a defensibly low-risk decision. We'll share the benchmark methodology behind our results — +31% throughput, −33% P99 latency, and 22–41% memory savings, confirmed across three independent tools — plus the blue-green rollout plan for both Sentinel and Cluster deployments.
