类 BigDecSerializer

java.lang.Object

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

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

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

所有已实现的接口:

Serializable

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

We create the BigDecSerializer instead of using the BigDecSerializer of flink-core module for performance reasons in Python deserialization.
