What is KeyDB?
KeyDB is an open-source, high-performance in-memory database that serves as a faster, multithreaded alternative to Redis. It is designed to handle heavy workloads, benchmarking at over 1 million operations per second on a single node, and provides sub-millisecond latencies by keeping data in-memory. KeyDB supports a variety of data structures and offers multiple persistence options for durability.
KeyDB is ideal for developers and organizations that require a highly scalable and performant data store, from small projects to applications serving millions of users. It offers advanced features like MVCC non-blocking architecture, cross-region multi-master support, and enhanced expiration capabilities. Its multithreaded design allows it to fully utilize modern server cores, reducing the need for complex sharding setups for many workloads and simplifying high availability configurations.
