    Definition Classes
    DfTransformer
  2. abstract def factory: FromConfigFactory[ParsableDfTransformer]

    Returns the factory that can parse this type (that is, type CO).

    Returns the factory that can parse this type (that is, type CO).

    Typically, implementations of this method should return the companion object of the implementing class. The companion object in turn should implement FromConfigFactory.

    returns

    the factory (object) for this class.

  17. def transformPartitionValues(actionId: ActionId, partitionValues: Seq[PartitionValues])(implicit context: ActionPipelineContext): Option[Map[PartitionValues, PartitionValues]]

    Optional function to define the transformation of input to output partition values.

    Optional function to define the transformation of input to output partition values. For example this enables to implement aggregations where multiple input partitions are combined into one output partition. Note that the default value is input = output partition values, which should be correct for most use cases.

    actionId

    id of the action which executes this transformation. This is mainly used to prefix error messages.

    partitionValues

    partition values to transform

    returns

    Map of input to output partition values. This allows to map partition values forward and backward, which is needed in execution modes. Return None if mapping is 1:1.
