Redis is an open-source, in-memory key-value data store. 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.

The tutorials included in this series cover a broad range of Redis commands, but they generally focus on connecting to a Redis database, managing a variety of data types, and troubleshooting and debugging problems, along with a few other more specific functions. They are written in cheat sheet format with self-contained examples. We encourage you to jump to whichever guide is relevant to the task you’re trying to complete.
