Redis is an in-memory key-value data store used for caching, session storage, queues, and real-time features, prized for its speed. It supports rich data structures beyond simple key-value.
Redis is an open-source, in-memory data store that can be used as a database, message broker, and caching layer. It supports data structures such as strings, hashes, lists, sets, and maps, and provides high performance and low latency.
