Highly Adaptable Query Optimizer Search Space Generation Process |
摘要 |
Systems, methods and articles of manufacture for determining at least one algorithm from a pool of algorithms to optimize a query. An embodiment includes building optimization blocks for the subplan, determining the complexity of the subplan based on the optimization blocks and selecting an algorithm from a pool of search space generation algorithms based on complexity of the subplan and characteristics of the selected algorithm, and optimizing the subplan with the selected algorithm. |
