Minimizing data movement through query transformation
Patrick Leyshock, David Maier, Kristin A. Tufte · 2014
Reducing data movement between desktop analytic systems and server-based data management systems is an important resource-management challenge. The system presented in this paper automatically minimizes data movement in these “hybrid” analytic systems through rewrite-based query-transformation techniques pioneered in relational database query optimization. We evaluate different classes of transformations both in terms of query improvement and optimization time.
