Load Shedding for Window Joins on Multiple Data Streams
2007
2007 IEEE 23rd International Conference on Data Engineering Workshop
We consider the problem of semantic load shedding for continuous queries containing window joins on multiple data streams and propose a robust approach that is effective with the different semantic accuracy criteria that are required in different applications. In fact, our approach can be used to (i) maximize the number of output tuples produced by joins, and (ii) optimize the accuracy of complex aggregates estimates under uniform random sampling. We first consider the problem of computing
