Class ArrayDataSerializer

java.lang.Object

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

org.apache.flink.table.runtime.typeutils.ArrayDataSerializer

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

All Implemented Interfaces:

Serializable

@Internal
public class ArrayDataSerializer
extends org.apache.flink.table.runtime.typeutils.ArrayDataSerializer

A TypeSerializer for ArrayData. It should be noted that the header will not be encoded. Currently Python doesn't support BinaryArrayData natively, so we can't use BaseArraySerializer in blink directly.
