Method Detail

translateForBatch

public Collection<Integer> translateForBatch(SinkTransformation<InputT,CommT,WriterStateT,GlobalCommT> transformation,
                                             TransformationTranslator.Context context)

Description copied from interface: TransformationTranslator

Translates a given Transformation to its runtime implementation for BATCH-style execution.

Specified by:

translateForBatch in interface TransformationTranslator<Object,SinkTransformation<InputT,CommT,WriterStateT,GlobalCommT>>

Parameters:

transformation - The transformation to be translated.

context - The translation context.

Returns:

The ids of the "last" StreamNodes in the transformation graph corresponding to this transformation. These will be the nodes that a potential following transformation will need to connect to.

translateForStreaming

public Collection<Integer> translateForStreaming(SinkTransformation<InputT,CommT,WriterStateT,GlobalCommT> transformation,
                                                 TransformationTranslator.Context context)

Description copied from interface: TransformationTranslator

Translates a given Transformation to its runtime implementation for STREAMING-style execution.

Specified by:

translateForStreaming in interface TransformationTranslator<Object,SinkTransformation<InputT,CommT,WriterStateT,GlobalCommT>>

Parameters:

transformation - The transformation to be translated.

context - The translation context.

Returns:

The ids of the "last" StreamNodes in the transformation graph corresponding to this transformation. These will be the nodes that a potential following transformation will need to connect to.
