    int
    getNumSubpartitions(int partitionIndex)
    Get number of subpartitions for the given partition.
    IntermediateDataSetID
    getResultId()
    Get the intermediate result id.
    boolean
    isBroadcast()
    Determines whether the associated intermediate data set uses a broadcast distribution pattern.
    boolean
    isPointwise()
    Whether it is a pointwise result.
    boolean
    isSingleSubpartitionContainsAllData()

  • Method Details

    • getResultId

      IntermediateDataSetID getResultId()
      Get the intermediate result id.
      Returns:
      the intermediate result id

    • isSingleSubpartitionContainsAllData

      boolean isSingleSubpartitionContainsAllData()
      Checks whether there is a single subpartition that contains all the produced data.
      Returns:
      true if one subpartition that contains all the data; false otherwise.

    • isBroadcast

      boolean isBroadcast()
      Determines whether the associated intermediate data set uses a broadcast distribution pattern.

      A broadcast distribution pattern indicates that all data produced by this intermediate data set should be broadcast to every downstream consumer.

      Returns:
      true if the intermediate data set is using a broadcast distribution pattern; false otherwise.

    • isPointwise

      boolean isPointwise()
      Whether it is a pointwise result.
      Returns:
      whether it is a pointwise result

    • getNumPartitions

      int getNumPartitions()
      Get number of partitions for this result.
      Returns:
      the number of partitions in this result

    • getNumSubpartitions

      int getNumSubpartitions(int partitionIndex)
      Get number of subpartitions for the given partition.
      Parameters:
      partitionIndex - the partition index
      Returns:
      the number of subpartitions of the partition
