Focus! Fast On-disk Concurrency-control Using Sketches
Summary: Decompose timestamp-based CC into a timestamp-storage layer plus protocol and introduce FPSketch, a compact sketch to approximate timestamps for inactive keys, drastically cutting memory and disk I/O while preserving correctness. In SplinterDB, FPSketch attains up to 14× speedups over 2PL/OCC and 5.9× over prior on-disk CC; 32KiB matches near-ideal in-memory performance, making timestamp CC practical for disk-based KV stores.
