| 摘 要： | 在基于共享硬件结构的并行数据库系统中，数据倾斜严重影响系统性能，数据重划分是实现数据物量重组织，解决数据放置倾斜的一种比较彻底的方法，本文提出了ＳＮ结构下并行数据库的静态和动态重划分算法，以及针对轮转重划分的静态算法，理论分析和实践表明算法是正确可行性的。

| Abstract: | The strategy of data partition is very important to performance on shared _nothing parallel database system. Because a database is dynamic, there is no one data partition of relation that is optimal for the lifetime of the database system. In this paper, we study static off line and dynamic on line algorithms of data repartition to improve the disk load balance. Then we described a lab to analysis the CPU cost of these algorithms. |
