| 摘 要： | 在OLTP应用中数据库集群是一种有效的并行处理方案，由于以前对数据库集群特别是异构情况下的性能评价不够完善，本文主要研究数据库异构集群的性能模型，分析了CPU和内存两种资源的异构带来性能影响，并给出了异构集群并行性的度量标准及系统有效性评估公式。最后，通过TPC-C实验表明数据库异构集群在OLTP处理中仍具有良好的可扩展性，次线性的加速比，以及高效费比的并行处理服务。

| Abstract: | Database cluster is an efficient parallel processing system in On-Line Transaction Processing (OLTP),since the previous performance evaluation of database cluster especially for heterogeneous case was incomplete,this paper mainly discusses the performance model of database heterogeneous cluster,analyzes the performance impact of two heterogeneous resources such as CPU and RAM,and presents the metrics of measuring the parallelism of heterogeneous cluster and estimates the system efficiency.The results of TPC-C experiments show that the database heterogeneous cluster still has advantages of good scalability,asymptotic speedup,and high efficient parallel service. |
