    Description

      This is because flatbuffers require writing in reverse order and we don't for record batches.
      The following method:
      org.apache.arrow.vector.file.ArrowFooter.endVector(FlatBufferBuilder, List<ArrowBlock>)
      Should use this one:
      org.apache.arrow.vector.schema.FBSerializables.writeAllStructsToVector(FlatBufferBuilder, List<? extends FBSerializable>)
