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    This interface has been replaced by DynamicTableSink.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.
