1) window join
窗口连接
1.
Furthermore, as window join is one of the highest cost operations of continuous queries, window join optimization will notably improve a DSMS performance.
提出适合频繁增删查询环境下的数据流窗口连接优化算法。
2.
Recently there has been a growing interest in sliding window join for scenarios, in which streams arrive at very high rates and a data stream management system is registered with many simultaneous queries.
提出一种多数据流滑动窗口连接方法M3Join及其实现架构Roujoin·Roujoin由一个连接路由表和多个连接区组成,其内容根据并发连接请求设置,先将新元组插入缓冲区,然后根据其路由标记查找连接路由表进入合适的连接区执行连接或输出给用户·如果产生连接元组,则更改其路由标记后送回连接路由表,并反复迭代直到没有连接元组·由于共享中间结果,在处理多个并发查询时只需扫描流元组一遍·实验结果表明M3Join具有良好的性能,能够满足并发连接查询处理的需求
2) shared window joins
共享窗口连接
3) shared window join

4) linked windows
连结窗口
5) contact window
