How Valkey 8.1 Handles 50 Million Sorted Set Inserts
The latest Valkey 8.1 release introduces a redesigned hash table and other optimizations that promise lower memory usage and higher throughput. In this post, we put Valkey 8.1 under pressure by benchmarking it against Valkey 8.0, inserting 50 million members into a sorted set and measuring memory consumption and throughput along the way.

Introducing Hash Field Expirations
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.
