摘要
结合文献[3,4]以及已有的一阶段提交协议,提出一种改进的E arly no P repare(ENP)协议。该协议消除了两阶段提交协议(2PC)中的处理消息阶段,参与者无需向协调者发送提交消息,子事务可自行决定提交或是终止,不必等待协调者的最终命令,从而降低消息复杂度和日志复杂度,保证了状态的一致性。
Referred the literatures[3, 4] and one-phase commit protocol, an improved commit protocol, called Early no Prepare （ENP）,is presented. The protocol eliminates the voting phase of 2PC. In this protocol, the participants don＇t need to send back “commit（ready）” message, the sub-transaction can decide by itself to commit or abort, and it is unnecessary to wait for coordinator＇s decision. In this way ,message and log complexities are reduced. At the same time, it promises the consistency.
