dc.description.abstract | This paper looks at how to effectively exploit pipelining for multi-join queries in shared-nothing systems. A multi-join query can be processed using an iterative approach. In each iteration, several relations are selected, and are joined in a pipelined fashion. However, algorithms that are based on this approach have traditionally assumed that the relations are uniformly distributed or lowly skewed. When this assumption is relaxed, that is when the data is skewed, some nodes may be assigned larger amount of data than can fit in their memories. As such, pipelining cannot be effectively exploited, and performance may degenerate drastically. We propose four skew handling techniques to deal with data skew for multi-join queries. The results of a performance study show that a hybrid technique is superior in most cases. | |
