Put an Elephant into a Fridge: Optimizing Cache Efficiency for In-memory Key-value Stores
Summary: Cavast tackles CPU-cache bottlenecks in terabyte-scale in-memory KVSs without hardware changes, using software cache control, cache-aware layout/index redesign, and GC offloading. Memcached/Redis prototypes achieve up to 82.7% cache hits and 4.2× throughput. (summarized by gpt-5.6-luna on Jul 24 2026)
