解决分布式数据库2PL执行-提交冲突的一种改进的乐观方法
An Improvement of OPT to Resolve Executing-Committing Conflict of Distributed Database Using 2PL
摘要
分布式数据库系统通常采用2PL(两阶段锁定协议)来维护其一致性。本文运用Shadow-Opt方法,通过区分写操作将新旧算法结合从而保证一致性并提高性能。
Distributed database systems usually use 2PL (Two Phase Locking Protocol) to assure the consistency. This paper uses Shadow-Opt, and combines the old and new algorisms to assure the consistency and improve the function by differentiating the write operation.
