Abstract
Technologies are disclosed for generating query execution plans optimized for parallel execution for programs having both core database relational functions and user-defined functions. A variety of optimization strategies can be employed to improve performance in a parallel execution scenarios. A flexible range of permitted partition arrangements can be specified as acceptable to parallelized instances of the user-defined function. The optimizer can leverage such information when constructing an optimized query execution plan. Partitioning arrangements or other properties can be leveraged to avoid additional or unnecessary processing.
