类 SqlTimestampSerializer

java.lang.Object

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

org.apache.flink.table.runtime.typeutils.SqlTimestampSerializer

所有已实现的接口:

Serializable

public class SqlTimestampSerializer
extends org.apache.flink.api.common.typeutils.TypeSerializer<SqlTimestamp>

Serializer of SqlTimestamp.

A SqlTimestamp 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.
