面向信息网模型的高可扩展性分布式事务处理机制
Distributed Transaction Processing Mechanism with High Scalability for Information Network Model
摘要
Abstract
The rapid increase in the amount of data have driven many database systems to provide nearlinearly scalability,but most of these systems cannot automatically maintain the strong consistent relation among objects.Aiming at this problem,this paper designs a distributed transaction processing mechanism with high scalability.For the semantic and storage characteristics of information network model,it dynamically controls the group commit size by the association between received transactions to use object caching and improve system throughput.Meanwhile,it concurrently executs the same operations between storage node and its replications rather than replicating with log,so as to improve the response speed.Experimental result shows that,compared with two-phase commit protocol,the proposed mechanism can obtain higher scalability which approximates to linear while ensuring strong transactional characteristic.It also has great improvement in system throughput and response time.关键词
