Redis is an in-memory key-value store that can be used as a cache or database. It supports a variety of data structures like strings, lists, sets, hashes and sorted sets. Redis has persistence options and is very fast due to being an in-memory store. It is compatible with many programming languages and is useful for tasks like caching, real-time rankings and generating temporary access tokens.
