PRDCC: PRedictive Deterministic Concurrency Control under High Contention
Summary: PRDCC predicts conflicts from extractable point/range predicates without physical pre-execution, with zero false negatives within its supported class. It deterministically partitions transactions into ordered execution blocks, reducing aborts and boosting high-contention throughput by up to 4.1× over Aria. (summarized by gpt-6-luna on Oct 22 2026)
