Abstract Value Members

  1. abstract def compatibleWith(other: Partitioning): Boolean

    Returns true iff all distribution guarantees made by this partitioning can also be made for the other specified partitioning.

    Returns true iff all distribution guarantees made by this partitioning can also be made for the other specified partitioning. For example, two HashPartitionings are only compatible if the numPartitions of them is the same.

  2. abstract def keyExpressions: Seq[Expression]

    Returns the expressions that are used to key the partitioning.

  3. abstract val numPartitions: Int

    Returns the number of partitions that the data is split across

  4. abstract def satisfies(required: Distribution): Boolean

    Returns true iff the guarantees made by this Partitioning are sufficient to satisfy the partitioning scheme mandated by the required Distribution, i.e.

    Returns true iff the guarantees made by this Partitioning are sufficient to satisfy the partitioning scheme mandated by the required Distribution, i.e. the current dataset does not need to be re-partitioned for the required Distribution (it is possible that tuples within a partition need to be reorganized).
