Class DecimalDataSerializer

java.lang.Object

org.apache.flink.api.common.typeutils.TypeSerializer<org.apache.flink.table.data.DecimalData>

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

All Implemented Interfaces:

Serializable

@Internal
public class DecimalDataSerializer
extends org.apache.flink.api.common.typeutils.TypeSerializer<org.apache.flink.table.data.DecimalData>

We create the DecimalSerializer instead of using the DecimalSerializer of flink-table-runtime-blink for performance reasons in Python deserialization.
