What is Redis?

Redis is an open-source key-value data store known for its flexibility, performance, and wide language support. An in-memory database, Redis is also known for its speed and has found wide use as a cache and message broker, as well as a database.

A NoSQL database, Redis doesn’t use structured query language, otherwise known as SQL. Redis instead comes with its own set of commands for managing and accessing data.
