Instance Constructors

  1. new CoalescedPartitioner(parent: Partitioner, partitionStartIndices: Array[Int])

    parent

    a parent partitioner

    partitionStartIndices

    indices of partitions in parent that should create new partitions in child (this should be an array of increasing partition IDs). For example, if we have a parent with 5 partitions, and partitionStartIndices is [0, 2, 4], we get three output partitions, corresponding to partition ranges [0, 1], [2, 3] and [4] of the parent partitioner.
