Distributed streaming query planner in Calder system
Ying Liu, Beth Plale, Nithya N. Vijayakumar · 2005
The contribution of this work has two folds. First, we extend the current query planners' cost metric space by introducing network bandwidth cost, query deployment cost and query re-using cost; second, we develop a suite of algorithms for re-using existing query fragments under different scenarios. One of the most important reusable queries is called structure-sharable query.
