Package org.apache.flink.streaming.api.transformations

Class SideOutputTransformation<T>

  • Type Parameters:
    T - The type of the elements that result from this SideOutputTransformation
    public class SideOutputTransformation<T>
extends org.apache.flink.api.dag.Transformation<T>
    This transformation represents a selection of a side output of an upstream operation with a given OutputTag.

    This does not create a physical operation, it only affects how upstream operations are connected to downstream operations.
