网络系统并行数据库中数据均衡分配方案的探讨

THE DATA BALANCE DISTRIBUTION OF PARALLEL DB BASED ON THE NETWORK SYSTEM

介绍了网络并行机群的特点以及目前并行机系统新的发展趋势 ,分析了网络并行机群环境下 ,并行数据库数据分布中数据倾斜问题的特点 ,提出了一种具有适应环境能力的动态数据均衡分配方案。

Based on the feature of network computers and the new developing tend of the present parallel computer system,this article analyses the feature of data sloping problem in the distribution of parallel DB in the environment of parallel network,and puts forword a kind of dynamic distribution method of data balance with the ability of adapting the environment.
