Abstract
Systems and apparatuses are provided for a distributed aggregate user defined function processing system. A non-transitory computer readable medium stores instructions for a query compiler to identify a call to a distributed aggregate user defined function within a query of the distributed analytical data processing system, retrieve metadata associated with the distributed aggregate user defined function, and validate and resolve respective inputs and outputs of a plurality of function partitions associated with the distributed aggregate user defined function according to the retrieved metadata. A distributed processing engine includes a plurality of processing nodes to execute the plurality of function partitions and organize data flow from the plurality of function partitions to produce an output for the distributed aggregate user defined function.
