T
- The type of value in the StreamRecord@Internal public final class MultiplexingStreamRecordSerializer<T> extends TypeSerializer<StreamElement>
StreamRecord
and Watermark
. This does not behave like a normal
TypeSerializer
, instead, this is only used at the stream task/operator level for
transmitting StreamRecords and Watermarks.Constructor and Description |
