@Internal
public class DataSinkFunctionOperator
extends org.apache.flink.streaming.api.operators.StreamSink<org.apache.flink.cdc.common.event.Event>

An operator that processes records to be written into a SinkFunction.

The operator is a proxy of StreamSink in Flink.

The operator is always part of a sink pipeline and is the first operator.
