Plor: General Transactions with Predictable, Low Tail Latency
Summary: Plor: hybrid concurrency control with pessimistic locking and optimistic reads for in-memory transactions, targeting high-contention workloads. Conflict checks delayed to commit; older txs commit first by timestamp, yielding low tail latency and solid throughput. (summarized by gpt-5-nano on Feb 09 2026)
