Type Parameters:

T - Type of records that this TableSink expects and supports.

All Superinterfaces:

StreamTableSink<Tuple2<Boolean,T>>, TableSink<Tuple2<Boolean,T>>

Deprecated.

This interface has been replaced by DynamicTableSink. The new interface consumes internal data structures. See FLIP-95 for more information.

@Deprecated
 @PublicEvolving
public interface RetractStreamTableSink<T>
extends StreamTableSink<Tuple2<Boolean,T>>

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 T.

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

A message with false flag is a retract message.
