Sliding Window Counter Strategy
Learn about the Sliding Window Counter, a more memory-efficient approach that approximates the log method for practical use.
Intro to Sliding Window Counter
Welcome to our lesson on the Sliding Window Counter (SWC) algorithm!
This algorithm is a clever way to implement rate limiting. It aims to offer better accuracy than the simple Fixed Window Counter, while being more memory-efficient than the precise Sliding Window Log.
Fixed Window's Flaw
Recall that the Fixed Window Counter can suffer from a 'burst' problem. If a user makes requests right at the end of one window and then again right at the start of the next, they can effectively double their allowed requests in a short period.
The Sliding Window Counter helps to mitigate this issue.
