Token Bucket Algorithm Mechanics
Explore the token bucket algorithm, understanding its flexibility in allowing bursts and its common use cases in modern systems.
Meet the Token Bucket
Welcome to the Token Bucket algorithm! After exploring fixed windows and leaky buckets, we'll now dive into a flexible approach that’s widely used in modern systems.
The Token Bucket is a rate-limiting algorithm that allows for bursts of traffic while still enforcing an average rate limit.
Tokens in a Virtual Bucket
Imagine a virtual 'bucket' that holds a certain number of 'tokens'. Each token represents permission for one API request.
- When a request arrives, it tries to take a token.
- If a token is available, the request proceeds, and the token is removed.
- If no tokens are available, the request is typically denied or queued.
