接口 DelegateOperatorTransformation<OUT>

所有已知实现类:

PythonBroadcastStateTransformation, PythonKeyedBroadcastStateTransformation

public interface DelegateOperatorTransformation<OUT>

For those Transformation that don't have an operator entity, DelegateOperatorTransformation provides a SimpleOperatorFactory containing a DelegateOperatorTransformation.DelegateOperator , which can hold special configurations during transformation preprocessing for Python jobs, and later be queried at translation stage. Currently, those configurations include OutputTags, numPartitions and general Configuration.
