Patent abstract
Described herein are techniques for Configuration-Parametric Query Optimization (C-PQO) that can improve performance of database tuning tools. When first optimizing a query, a compact representation of the optimization space is generated. The representation can then be used to efficiently produce other execution plans for the query under arbitrary hypothetical configurations.
