Valkey

Valkey at a glance

Valkey is an open-source, high-performance in-memory data store — a community-driven, Linux Foundation fork of Redis created after its license change, and a drop-in replacement for many workloads. Valkey ships regular releases plus security fixes.

For admins Valkey behaves like Redis: the cardinal rule is never to expose it to the internet unprotected — enable authentication and TLS and bind it to the internal network, since an open in-memory store is a data-leak (and takeover) risk. Updates are low-risk with replication (update the replica, then fail over). The data format is compatible with Redis, easing migration, though the projects will diverge over time — check specifics. For larger security advisories, patch promptly. After updating, verify replication and client connectivity. Track the version and its support status; patchletter surfaces new Valkey releases.
