Valkey, an open source key-value database under the Linux Foundation, announced the general availability of Valkey 9.0—introducing expiration dates for hash fields, atomic slot migration, and multiple databases in cluster mode, which fortify Valkey's use at scale.
According to the vendor, a Valkey 9.0 cluster can support over 1 billion requests per second, delivering on new capabilities for scalability, reliability, and efficiency in distributed data environments, all while reducing cost and overhead for engineering teams.
Valkey 9.0 continues the project's mission to provide a fully open, community-driven in-memory data store that evolves with modern application needs.
When compared with version 8.1, users of Valkey 9.0 experience up to 40% more throughput in their applications of the project, the vendor said.
This version represents significant progress in horizontal scalability and compute efficiency—areas that have traditionally challenged distributed systems.
"Valkey 9.0 is a game changer for us," said Khawaja Shams, co-founder and CEO of Momento. "It allows us to support larger working sets and higher throughput with the same hardware, translating into massive efficiency gains at our scale. Valkey's inclusive community has also consistently fueled our team's ambition. The project keeps outpacing itself, and we're thrilled to be part of that journey."
Users of Valkey 9.0 will gain three banner features in this latest release: hash field expiration, atomic slot migration, and multiple databases in cluster mode.
Additional upgrades in Valkey 9.0 include:
- Memory prefetching for pipelining commands – up to 40% higher throughput
- Zero-copy responses for large requests – with up to 20% higher throughput
- SIMD optimizations for BITCOUNT and hyperloglog commands – up to 200% higher throughput
- Support for Multipath TCP – up to 25% lower latency
- By-polygon support for Geospatial Indexes
"One of our goals is to make Valkey as resilient as possible, so that our users can depend on it for serving their application traffic," said Madelyn Olson, maintainer of Valkey and principal software engineer at AWS. "Valkey 9.0 is a major step forward in that direction with larger and more stable clusters that can more easily scale to meet user demands."
