OrderedDistribution

case class OrderedDistribution(ordering: Seq[SortOrder]) extends Distribution with Product with Serializable

Represents data where tuples have been ordered according to the ordering Expressions. Its requirement is defined as the following:

  • Given any 2 adjacent partitions, all the rows of the second partition must be larger than or equal to any row in the first partition, according to the ordering expressions.

In other words, this distribution requires the rows to be ordered across partitions, but not necessarily within a partition.
