Redis is renowned for its blazing-fast in-memory data store capabilities, making it an excellent companion for high-performance web applications. In this article, we will walk through integrating Redis with FastAPI, providing practical examples and use cases demonstrating its power.

Why Use Redis with FastAPI?

FastAPI is a modern Python framework designed to build APIs efficiently. Combining FastAPI with Redis can yield numerous benefits:

• Caching: Reduce database load by caching frequently accessed data.
• Session Management: Store user sessions efficiently for authentication.
• Rate Limiting: Implement rate limiting to prevent abuse of APIs.
• Pub/Sub: Enable real-time communication features.

In this article, we are implementing caching using Redis but before that let’s first set up Redis using Docker. If you don’t have Docker installed, head over to the Docker website and install it for your operating system.
