First thing first.

Redis is not actually a database at least not like any SQL or NoSQL databases out there. One could argue it's a NoSQL database since it stores data in key-value pairs. And it'd not be a wrong statement.

It's a database but it's not a database. Okay okay, hold on it's a database but used just for caching.

The important thing here is you need to know that, it is a RAM-based data storing system mostly used on the top of any database of your choice for caching your application in production to speed up your application by a significant amount of time.

You can use it with pretty much any website or application you build using any of the available tech stacks.

Here we are gonna have a look at how we can use Redis with Django web applications for caching
