Abstract:

Online transaction processing systems use two-phase locking (2PL) to guarantee serializability. However, traditional 2PL does not perform well under high contention, because a transaction will be blocked when it fails to acquire lock. This paper proposes a scalable work stealing algorithm for 2PL to leverage intra-transaction parallelism....More
