| 英文摘要 | Join is a fundamental operator in a Data Stream Management System (DSMS). It is more efficient to share execution of multiple windowed joins than separate execution of everyone because the former saves a part of cost in common windows. Therefore, shared window join is adopted widely in multiqueries DSMS. When all tasks of queries exceed maximum system capacity, the overloaded DSMS fails to process all of its input data and keep up with the rates of data arrival. Especially in a time-critical environment, queries should be completed not just timely but within certain deadlines. In this paper, we address load shedding approach for shared window join over real-time data streams. A load shedding algorithm LS-SJRT-CW is proposed to handle queries shared window join in overloaded real-time system effectively. It would reduce load shedding overhead by adjusting sliding window size. Experiment results show that our algorithm would decrease average deadline miss ratio over some ranges of workloads. © Springer-Verlag Berlin Heidelberg 2009. |
