【摘要】 原有3PC分布式事务提交协议能克服协同者发生故障而有可能产生事务阻塞问题,但其开销大。该文提出了一种基于代理的3PC事务提交协议,该协议通过增加协同者的代理节点,使得参与者相信协同者是正常的,从而不必关心新协同者的选举问题,能降低3PC无故障时的额外开销。更多还原

【Abstract】 3PC commitment protocol can overcome the blocking problem caused by coordinator fault, but it brings extra overhead. This paper proposes a 3PC protocol based on proxy, in which the participants believe that the coordinator is fault-free by constructing proxy of coordinator. In the protocol, the participant need not consider to vote new coordinator, lowering the overhead of the original 3PC.更多还原
