Package org.apache.flink.legacy.table.sinks

Interface RetractStreamTableSink<T>

Type Parameters:
T - Type of records that this TableSink expects and supports.
All Superinterfaces:
StreamTableSink<org.apache.flink.api.java.tuple.Tuple2<Boolean,T>>, org.apache.flink.table.legacy.sinks.TableSink<org.apache.flink.api.java.tuple.Tuple2<Boolean,T>>
@Deprecated @Internal public interface RetractStreamTableSink<T> extends StreamTableSink<org.apache.flink.api.java.tuple.Tuple2<Boolean,T>>
Deprecated.
This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.
Defines an external TableSink to emit a streaming Table with insert, update, and delete changes.

The table will be converted into a stream of accumulate and retraction messages which are encoded as Tuple2. The first field is a Boolean flag to indicate the message type. The second field holds the record of the requested type RetractStreamTableSink.

A message with true Boolean flag is an accumulate (or add) message.

A message with false flag is a retract message.
