Abstract

Annotations can be placed in source code to indicate properties for user-defined functions. A wide variety of properties can be implemented to provide information that can be leveraged when constructing a query execution plan for the user-defined function and associated core database relational operations. A flexible range of permitted partition arrangements can be specified via the annotations. Other supported properties include expected sorting and grouping arrangements, ensured post-conditions, and behavior of the user-defined function.
