Inspired by highly skewed data popularity and short-term hotspot stability in cache workloads, FrozenHot splits cache space into a frozen cache and a dynamic cache. The frozen cache serves hot objects with minimal latency by eliminating cache management locks, while the dynamic cache uses existing designs for workload adaptability.
