Valkey 9.1 trims memory by 10% and brings search into the core

Valkey 9.1 is now generally available, with up to 10% lower per-key memory usage for common workloads.

The release adds security and cluster management upgrades, including database-level ACLs, TLS certificate reloading, and CLUSTERSCAN support.

Valkey Search is updated with full-text and vector search, bringing search capabilities into the core platform.

The changes can lower infrastructure costs, strengthen multi-tenant security, and simplify operations by combining storage and search.
