摘要
本文论述了分布式数据库系统中常用的事务提交协议并对其特点进行了分析,结合2PC协议和3PC协议的优缺点,提出了一种基于冗余技术的改进三段提交协议,该协议通过增加协调者副本队列来减少信息交换量和阻塞次数,提高了事务执行的成功率,改善了提交协议的性能。
In this paper, we give a brief discussion on transaction commit protocol of distributed database system and an analysis of its features. Combined the advantage with disadvantage of 2 PC and 3 PC , this article puts forwards a new three - phase commit protocol on the basis of redundancy technique. This protocol can decrease the times of information exchange and blocking thought, and increase the redundancy of coordinator. This protocol can also increase the probability for transaction success, and improve the performance for protocol commitment.
