ClusteredDistribution

Related Doc: package physical

case class ClusteredDistribution(clustering: Seq[Expression]) extends Distribution with Product with Serializable

Represents data where tuples that share the same values for the clustering Expressions will be co-located. Based on the context, this can mean such tuples are either co-located in the same partition or they will be contiguous within a single partition.
