Redis is a dynamic and open-source (BSD licensed) in-memory data structure store that serves multifunctional roles as a database, cache, and message broker. Operating as a NoSQL database, Redis liberates users from the constraints typically associated with relational databases, allowing for the storage of extensive data volumes.

Redis operates on the fundamental principle of a key-value store, enabling users to store specific data, known as a “value,” within designated “keys.”

Additionally, Redis offers robust support for a diverse range of data structures, encompassing strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, and geospatial indexes, complete with the capability for radius queries.
