How it works?
Assuming a limit of 5 requests per minute
- Every time we receive a request, we check if we have received 5 or more requests in the last 1 minute
- When a request is received, its timestamp is logged. This logging of timestamp helps us count the number of requests received in the last minute
Pros and Cons
Pros
- Accurate rate limiting due to the rolling window
Cons
- Memory intensive
