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

Class AbstractBroadcastStateTransformation<IN1,IN2,OUT>

java.lang.Object
org.apache.flink.api.dag.Transformation<T>
org.apache.flink.streaming.api.transformations.PhysicalTransformation<OUT>
org.apache.flink.streaming.api.transformations.AbstractBroadcastStateTransformation<IN1,IN2,OUT>
Type Parameters:
IN1 - The type of the elements in the non-broadcasted input.
IN2 - The type of the elements in the broadcasted input.
OUT - The type of the elements that result from this transformation.
Direct Known Subclasses:
BroadcastStateTransformation, KeyedBroadcastStateTransformation
@Internal public class AbstractBroadcastStateTransformation<IN1,IN2,OUT> extends PhysicalTransformation<OUT>
Base class for Broadcast State transformations. In a nutshell, this transformation allows to take a broadcast (non-keyed) stream, connect it with another keyed or non-keyed stream, and apply a function on the resulting connected stream.

For more information see the Broadcast State Pattern documentation page.
