The Linux Foundation has announced the release of Valkey 8.0, the latest version of the open source in-memory, NoSQL data store. Valkey 8.0 showcases rapid innovation with significant updates designed to boost performance, reliability, and observability for all installations. This release enhances the foundation by building upon the strengths of our previous open source versions by introducing new features that elevate Valkey.

Key highlights of the release include:

• Intelligent multi-core utilization and asynchronous I/O threading improves throughput up to 1.2 million requests per second on AWS r7g instances, over 3x higher than the previous version
• Improved cluster scaling with automatic failover for new shards and replicated migration states
• Faster replication with dual-channel RDB and replica backlog streaming
• Comprehensive per-slot and per-client metrics, including pubsub clients, rehash memory, event loop latency, and command-level heavy traffic logging, provide granular visibility into performance and resource usage
• Up to 10% reduced memory overhead through optimized key storage

Valkey 8.0 is now available today for download on valkey.io, and existing users can upgrade with a few simple commands. Valkey can be built directly from source or deployed using pre-built container images.

The Valkey team will also be onsite at Open Source Summit Europe, taking place in Vienna this week (Sept 16-18).
