Abstract
The cost of query optimization is affected by both the search space and the search strategy of the optimizer. In a parallel execution environment, the search space tends to be much larger than in the centralized case. This is due to the high number of execution alternatives which implies a significant increase in the optimization cost. In this paper, we investigate the trade-off between optimization cost and parallel execution cost using the DBS3 parallel query optimizer. We describe its cost model which captures all essential aspects of parallel executions. We show how the cost metrics imply a significant increase in the search space and optimization cost. However, instead of restricting the search space, which may lead to loosing better plans, we reduce the optimization cost bycontrolling the search strategy. We extend randomized strategies to adapt well to parallel query optimization. In particular, we propose Toured Simulation Annealing which provides a better trade-off between optimization cost and quality of the parallel execution plan.
