Using Redis for caching in FastAPI

Redis is an in-memory data store that can be used as a cache to improve the performance and scalability of FastAPI applications. By caching frequently accessed data in Redis, you can reduce the load on your database and speed up response times for your API endpoints.

In this recipe, we’ll explore how to integrate Redis caching into our streaming platform application and we will cache an endpoint as an example.

Getting ready

To follow along with the recipe you need a running Redis instance reachable at the http://localhost:6379 address.

Depending on your machine and your preference, you have several ways to install it and run it. Have a look at the Redis documentation to see how to do it for your operating system: https://redis.io/docs/install/install-redis/.

In addition, you need a FastAPI application with an endpoint that is time consuming.

Alternatively, if you follow the streaming platform, make sure that you have created...
