Paper Abstract:
|
The disparate and geographically distributed data sources in an enterprise can be integrated using distributed computing
technologies such as data grids. The real challenge involved such data integration efforts is in the design and
development of the distributed query processing engine that lie beneath such integrated systems. In the current literature,
distributed query processing and optimization is carried out in three distinct phases namely, (1) creation of single node
plan, (2) generation of parallel plan, and (3) optimal site selection for plan execution. As considering the three phases in
isolation leads to sub-optimal plans, we propose a distributed query optimization model that integrates all the three phases
of the query optimization. We present different heuristic approaches for solving the proposed integrated distributed query
processing problem. We also provide series of performance experiments to validate the robustness of the heuristic search
procedure. |
