Redis is an open-source, in-memory data structure store that is used as a database, cache, and message broker. It supports various data structures such as strings, hashes, lists, sets, and sorted sets. Redis provides high-performance operations for read and write operations due to its in-memory architecture. It also supports persistence mechanisms for backing up data to disk and replication for scaling the system horizontally. Redis is widely used by developers for building scalable applications that require real-time processing of large amounts of data with low latency.
