Tobi Bosede commented on SPARK-10915:
-------------------------------------

Thanks Davies. Someone also mentioned collect on the mailing list. I think I will use pandas'
pivot for now rather than collect and create a UDF. (Hopefully I have enough memory). 
So how are the current (built in) aggregate functions being implemented? They are batch right?
