[Posted October 21, 2025 by jzb]

Version 9.0.0 of the Valkey distributed key-value database has been released. Notable features of this release include Multipath TCP (MPTCP) support, new filters for client commands, multi-database support for cluster mode and much more. See the Valkey 9.0.0 RC1 release notes for a full list of new features in this major release.

According to a recent blog post, this release includes major improvements to performance and scaling of Valkey clusters to more than 2,000 nodes and one billion requests per second. Valkey began as a fork of the Redis key-value database in March 2024, but has evolved separately since then.
