Hi, all While working on the issue to implement dictionary-encoded subfields[1] [2], I found FixedSizeListVector not extends ListVector(Thanks Micah pointing this out and curious why implemented FixedSizeListVector this way before). Since FixedSizeListVector is a specific case of ListVector, should we make former extends the latter to reduce the plenty duplicated logic in these two and writer/reader classes?
Thanks, Ji Liu [1] https://issues.apache.org/jira/browse/ARROW-1175[2]https://github.com/apache/arrow/pull/4972
