what is sdk SizedColumnTypes::addIntPartitionColumn method for
I'm looking for a way to tell vertica that columns coming from my udtf are sorted and partitioned in a specific manner so there is no need to resegment and reorder result dataset. I see there are planty of methods like addIntPartitionColumn and addIntOrderColumn in a SizedColumnTypes class. But setting them in a TransformFunctionFactory::getReturnType makes no difference. What are they for? And is there any way to tell vertica output sortedness for udtf result?
I'm kinda stuck with it. Any advice appreciated
