What are the different rate limiting algorithms and how do they compare?

There are several rate limiting algorithms, including Token Bucket, Leaky Bucket, Fixed Window, and Sliding Window. Each has its own strengths and weaknesses.

Can you explain how the Token Bucket algorithm works?

Sure! The Token Bucket algorithm allows a certain number of requests to be processed at a time, controlled by tokens. Tokens are added to the bucket at a fixed rate, and each request consumes a token.

What are the advantages of using the Leaky Bucket algorithm?

The Leaky Bucket algorithm smooths out bursts of traffic by processing requests at a constant rate, which helps prevent server overload.

How do Fixed Window and Sliding Window algorithms differ?

Fixed Window resets the count after a fixed time period, while Sliding Window allows for more flexibility by considering the time of each request, providing a more accurate rate limit.
