This paper presents a novel strategy for temporal coalescing. Temporal coalescing merges the temporal extents of value-equivalent tuples. A temporal extent is usually coalesced of...
In many applications, the underlying data (the web, an XML document, or a relational database) can be seen as a graph. These graphs may be enriched with weights, associated with t...
The query execution engine in Microsoft SQL Server employs hash-based algorithms for inner and outer joins, semi-joins, set operations (such as intersection), grouping, and duplic...
We introduce a novel spatial join operator, the ring-constrained join (RCJ). Given two sets P and Q of spatial points, the result of RCJ consists of pairs p, q (where p P, q Q) ...
In this paper, we present an adaptive load diffusion operator to enable scalable processing of Multiway Windowed Stream Joins (MWSJs) using a cluster system. The load diffusion is...
