Redis, an open-source (BSD licensed) solution, serves as a versatile in-memory data structure store, offering capabilities as a database, cache, and message broker. As a NoSQL database, Redis provides users with the flexibility to store substantial volumes of data without the constraints typically associated with relational databases.
Redis operates on the foundational principle of a key-value store, enabling the storage of data referred to as a “value” within a specific “key.”
Furthermore, Redis boasts support for a wide array of data structures, encompassing strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, and geospatial indexes with radius queries.
