类 TimestampSerializer

java.lang.Object

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

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

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

所有已实现的接口:

Serializable

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

Uses similar serialization/deserialization of SqlTimestampSerializer to serialize Timestamp. It deals with Daylight saving time problem and precision problem.
