摘要：

随着新型分布式系统的使用范围越来越广, 应用不再满足于仅使用主键访问方式来读取数据, 如何在这些系统中高效实现 Join 等复杂操作成为研究的热点. 本文介绍了如何基于 Semi-Join 算法在分布式系统中实现 Join 操作, 提出了两种获取右表数据的方法, 并通过实验分析了该算法的性能.

Abstract:

As the scope of application of the new distributed system is becoming wider, the application is no longer satisfied with using primary key access to read the data, and how to efficiently achieve such complex operations as Join in these systems has become a research hot topic. This paper introduces how to realize the Join operation in the distributed systems based on the Semi-Join algorithm, and puts forward two ways to get the data in right table, and the performance of the algorithm is also analyzed through experiments.
