KeyDB
Open SourceFundedHigh-performance, multithreaded open source database alternative to Redis
About KeyDB
KeyDB is a fully open source, multithreaded database designed to deliver high throughput and low latency for demanding workloads. It serves as a faster drop-in replacement for Redis, supporting a wide variety of data structures such as strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geospatial indexes, and streams. KeyDB is suitable for enterprises needing scalable, reliable, and fast in-memory data storage solutions to enhance user experience across applications serving millions of users.
Built for scale, KeyDB supports vertical scaling on single nodes and horizontal scaling through active replication and cluster mode with sharded datasets. It offers multiple persistence options, high availability with active-replica failover without sentinel nodes, and advanced open source features like MVCC non-blocking architecture, cross-region multi-master support, and enhanced expiration handling. Its multithreaded design also enables TLS encryption at significantly higher throughput than Redis, making it suitable for secure enterprise deployments. KeyDB’s extensibility includes an open source JavaScript module for custom commands, appealing to organizations seeking flexible and performant database platforms.
