On the flip side, cut down is an action that aggregates all the elements of the RDD using some function and returns the ultimate result to the driver method (Despite the fact that There's also a parallel reduceByKey that returns a distributed dataset).
Repartition the RDD in accordance with the provided partitioner and, within Each individual resulting partition, form information by their keys. This is more productive than calling repartition after which you can sorting in Each and every partition because it can force the sorting down to the shuffle machinery.
