01 Description

Redis is an in-memory data structure store, used as a distributed, in-memory key–value database, cache and message broker, with optional durability. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indices.

Redis enables you to write traditionally complex code with fewer, simpler lines. With Redis, you write fewer lines of code to store, access, and use data in your applications. The difference is that developers who use Redis can use a simple command structure as opposed to the query languages of traditional databases.
