Tag: Redis Cheat Sheet

The Redis cheat sheet includes basic syntax and methods to help you using Redis. Redis is an open-source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams.
