Hotspot Detection and Local Cache Framework for High‑Traffic Applications

The presented hotspot detection and local‑cache framework leverages the HeavyKeeper streaming top‑k algorithm with decay‑based burst detection, integrates zero‑code SDK support and a whitelist‑enabled LRU cache, enabling a few megabytes of memory to achieve up to 85% hit rates and dramatically reduce Redis load in high‑traffic applications.
