org.apache.flink.connector.kafka.sink

Interface TwoPhaseCommittingStatefulSink<InputT,WriterStateT,CommT>

Type Parameters:

InputT - The type of the sink's input

WriterStateT - The type of the sink writer's state

CommT - The type of the committables.

All Superinterfaces:

Serializable, org.apache.flink.api.connector.sink2.Sink<InputT>, org.apache.flink.api.connector.sink2.StatefulSink<InputT,WriterStateT>, org.apache.flink.api.connector.sink2.TwoPhaseCommittingSink<InputT,CommT>

All Known Implementing Classes:

KafkaSink

@Internal
public interface TwoPhaseCommittingStatefulSink<InputT,WriterStateT,CommT>
extends org.apache.flink.api.connector.sink2.TwoPhaseCommittingSink<InputT,CommT>, org.apache.flink.api.connector.sink2.StatefulSink<InputT,WriterStateT>

A combination of TwoPhaseCommittingSink and StatefulSink.

The purpose of this interface is to be able to pass an interface rather than a KafkaSink implementation into the reducing sink which simplifies unit testing.
