@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 directly.
