Abstract
Systems and apparatuses are provided for integrating user defined functions into an analytical data processing framework. A query compiler (22) identifies a call to a user defined function (28) and one of a GROUP BY expression and a defined online analytics processing (OLAP) window associated with the user defined function. A database engine (24) executes the user defined function (28) with a partition set defined by the one of the GROUP BY expression and the defined OLAP window, such that the user defined function operates on the partition set to produce a function output.
