Introducing Hash Field Expirations

Tuesday, September 30, 2025 · ranshid

One of Valkey’s greatest strengths has always been its built-in ability to expire keys. This simple but powerful feature helps developers keep datasets fresh, automatically clear caches, and enforce session lifetimes — all without extra application logic. But until now, expiration worked only at the level of entire keys. In this post, we’ll explore how Valkey 9.0 introduces per-field expiration for hash objects, the challenges we faced designing it, the tradeoffs we considered, and the benchmarks that guided our final implementation. We’ll also walk through practical examples to show how you can start using this feature today.
