    • 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.
