Class TimeSerializer

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<T>

org.apache.flink.api.common.typeutils.base.TypeSerializerSingleton<Time>

org.apache.flink.table.runtime.typeutils.serializers.python.TimeSerializer

All Implemented Interfaces:

Serializable

@Internal
public class TimeSerializer
extends org.apache.flink.api.common.typeutils.base.TypeSerializerSingleton<Time>

Uses int instead of long as the serialized value. It not only reduces the length of the serialized value, but also makes the serialized value consistent between the legacy planner and the blink planner.
