About

Precision matters when you are rate limiting. The sliding window log gives you accurate control over requests in real time. In this video, Raphael De Lio walks through how the algorithm works, why Redis is ideal for high-precision limits, and how to build it step by step in Java with Jedis. You will also explore practical optimizations like using a hash instead of a sorted set, hash field expiration, and what changes with Redis 8. Finally, you will test the implementation so it is ready for production.
