Y'all know Valkey right? We co-maintain it upstream
And now we support Valkey 9.0 (up to 200% throughput gains on compute-heavy ops) with a set of kernel-level patches built for prod:
- Stateful connections (Pub/Sub, MULTI) survive node migration without dropping
- Rehash latency spikes minimized at the root, keeping data service stable and smooth under load
- Same-zone replica wins the failover election, avoiding the latency hit and performance loss from cross-zone switches
For agent builders: pipeline memory prefetch in 9.0 cuts batch read latency by up to 40% and zero-copy responses add another 20% on large value reads.
I bet it's worth a look:
