Rate Limiting is a way to limit the number of requests within a specific period. It is super helpful when you have many requests and want to reduce load.

This post will show you two different algorithms for implementing rate limiting in Python from scratch.

Naive Fixed Window Algorithm

The most straightforward algorithm to do rate limiting is the fixed window algorithm.
