public interface StreamTableSink<T>
extends org.apache.flink.table.sinks.TableSink<T>

Defines an external stream table and provides write access to its data.

Method Summary

Modifier and Type	Method and Description
default org.apache.flink.streaming.api.datastream.DataStreamSink<?>	consumeDataStream(org.apache.flink.streaming.api.datastream.DataStream<T> dataStream) Consumes the DataStream and return the sink transformation DataStreamSink.
void	emitDataStream(org.apache.flink.streaming.api.datastream.DataStream<T> dataStream) Deprecated. This method will be removed in future versions as it returns nothing. It is recommended to use consumeDataStream(DataStream) instead which returns the DataStreamSink. The returned DataStreamSink will be used to set resources for the sink operator. If the consumeDataStream(DataStream) is implemented, this method can be empty implementation.
