Sliding Window Log Implementation
Understand the Sliding Window Log algorithm, its precision, and the storage implications for tracking individual request timestamps.
Intro to Sliding Window Log
Welcome to the Sliding Window Log algorithm! This method offers a highly precise way to enforce API rate limits.
Unlike simpler methods, it keeps a detailed record of each request, allowing for very accurate control over traffic.
The Timestamp Log Core
The core idea of the Sliding Window Log is to store the exact timestamp of every request made by a client.
- Imagine a list or array.
- Each time a request is made, its current time (e.g., in milliseconds) is added to this list.
- This log allows us to precisely track activity over any given period.
