Ideally, an approach for information recovery should have the following features. First, it should be able to incorporate prior knowledge about the data, even if such knowledge is in the form of complex distributions and constraints for which...
Tuple dropping, though commonly used for load shedding in most data stream operations, is generally inadequate for multiway windowed stream joins. The join output rate can be unnecessarily reduced because tuple dropping fails to exploit the time correlations that are likely to exist among interrelated streams. In this paper, we introduce GrubJoin-an adaptive multiway windowed stream join that effectively...
