数据库集群中的数据分布策略研究

Data Distribution Strategy Study of Database Cluster

为了能平衡集群系统的负载且能减少数据频繁迁移所引起的系统开销,改进目前的均匀数据划分方式是非常必要的。并行处理、负载均衡与资源管理、数据分布等是数据库集群技术基础研究和工程应用现阶段主要面临的难题。

In order to balance the load ot cluster system, caused by frequent migration of date, it is necessary that improved uniform date partitioning approach. Parallel processing, load balancing and resource management and date distribution are the main challenges facing the datebase clustering technology in basic research and engineering applications at this stage.
