Percolator Distributed Transaction Architecture and Its Implementation in TiKV

Percolator implements a two‑phase commit transaction protocol with a client coordinator, a timestamp oracle, and storage (Bigtable or TiKV’s RocksDB), providing snapshot‑isolated ACID semantics via lock, write, and data columns; TiKV adds parallel prewrite, short‑value storage, point‑read shortcuts, calculated commit timestamps, and single‑region one‑phase commits to boost performance while keeping the design simple and scalable, though high contention can cause retries and read‑wait delays.
