A Cost-Space Approach to Distributed Query Optimization in Stream Based Overlays
Abstract— Distributed stream-based applications, such as continuous query systems, have network scale and time characteristics that challenge traditional distributed query optimi...

Coloring Away Communication in Parallel Query Optimization
We address the problem of finding parallel plans for SQL queries using the two-phase approach of join ordering and query rewrite (JOQR) followed by parallelization. We focus on t...
