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Early no Prepare (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。 |

Abstract: |
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. |
Key words: transaction commit protocol local transaction global transaction |
