Valkey Cluster

Valkey Cluster 9.1.0 is an open-source, high-performance, in-memory key-value datastore designed for caching, session storage, real-time workloads, queues, and distributed database use cases. Valkey Cluster provides horizontal scalability by distributing data across multiple Valkey nodes.

The solution supports common Valkey Cluster workflows including distributed key-value storage, automatic data sharding, replication, high availability, persistence, and command-line based administration. It is suitable for cloud-native applications, caching layers, session management, message queues, and high-performance backend workloads on Azure.
