Repartition the RDD according to the given partitioner and, in just Each individual ensuing partition, kind records by their keys. This is much more efficient than contacting repartition and after that sorting inside Every single partition because it can push the sorting down in the shuffle machinery.

The textFile system also can take an optional second argument for managing the quantity of partitions with the file. By default, Spark results in a single partition for visit here each block of the file (blocks becoming 128MB by default in HDFS), but It's also possible to ask for a greater amount of partitions by passing a larger benefit.
