Package 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.SupportsCommitter<CommT>, org.apache.flink.api.connector.sink2.SupportsWriterState<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.
