Research on Commit Method in Distributed Short Transaction Systems

Transactions in distributed short transaction system are usually short and asked frequently.Most of the exiting distributed commit protocols are designed for the complex long transaction system,therefore they can not meet the needs of short transactions.In this paper,an improved schema for distributed short transaction systems was proposed.By backuping logs and querying among participants,we can efficiently reduce the number of log-written,communications during the transaction and optimizing the failure processing.Compared with other distributed commit protocols and systems,this protocol can effectively improve the efficiency of services,and has a very high log availability.
