类 DateSerializer

java.lang.Object

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

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

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

所有已实现的接口:

Serializable

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

Takes 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.
