@Internal public class TimestampDataSerializer extends org.apache.flink.api.common.typeutils.TypeSerializer<org.apache.flink.table.data.TimestampData>
Serializer for TimestampData.

A TimestampData instance can be compactly serialized as a long value(= millisecond) when the Timestamp type is compact. Otherwise it's serialized as a long value and a int value.
