Constructor Detail

LegacySinkTransformation

public LegacySinkTransformation(org.apache.flink.api.dag.Transformation<T> input,
                                String name,
                                StreamSink<T> operator,
                                int parallelism,
                                boolean parallelismConfigured)

Creates a new LegacySinkTransformation from the given input Transformation.

Parameters:

input - The input Transformation

name - The name of the Transformation, this will be shown in Visualizations and the Log

operator - The sink operator

parallelism - The parallelism of this LegacySinkTransformation

parallelismConfigured - If true, the parallelism of the transformation is explicitly set and should be respected. Otherwise the parallelism can be changed at runtime.
