Package org.apache.flink.table.runtime.typeutils

Class TimestampDataSerializer

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<org.apache.flink.table.data.TimestampData>

org.apache.flink.table.runtime.typeutils.TimestampDataSerializer

All Implemented Interfaces:

Serializable

@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.
