摘要 分布式处理是数据流管理系统发展的必然趋势。研究了分布式数据流系统中的基于滑动窗口的连接操作,提出了DMS-Join算法。通过将多连接操作中的子操作分解置于不同的网络节点上,以减少数据的传输。分析与实验结果表明,DMS-Join算法具有较高的查询性能。 Following the development of database technology, distributed data stream-processing system becomes a hot research field. In this paper, we research on sliding window based join query, and propose a distributed multi data streams join query algorithm DMS-Join. By rearranging sub join query and locating them on various nodes; it can decrease the data transportation. The experimental results show that the algorithm is effective.
