@srowen That is controlled by scale - which is unfortunately not customizable (`val scale = math.max(math.ceil(math.pow(numPartitions, 1.0 / depth)).toInt, 2)`). The potential for increased cost was the reason I guess @akpatnam25 had the config (in my impl from quite a while back, I always did the final fold at executors when partitions > 1 :-) ). -- This is an automated message from the Apache Git Service.
