Redis
Redis is an open-source, high-performance in-memory database optimized for real-time applications, caching, and messaging.
About Redis
Redis is a BSD-licensed, in-memory data structure store that serves as a database, cache, and message broker. It supports advanced data types such as strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geospatial indexes, and streams. With features like replication, Lua scripting, LRU eviction, transactions, and persistence, Redis ensures high availability through Redis Sentinel and automatic partitioning with Redis Cluster.
