[GitHub] [arrow-datafusion] tustvold commented on issue #4502: Support writing lists in the arrow csv writer

   This would be an upstream issue in arrow-rs if we wish to add support for this, and I would be happy to review a PR adding support for it.
   
   That being said, I'm not sure how to encode nested data in CSV? I had understood the format to be strictly tabular? The docs for [arrow python](https://arrow.apache.org/docs/python/csv.html#reading-and-writing-csv-files) would appear to suggest only primitive types are supported although I haven't tested this?
   
   FWIW arrow-rs supports reading/writing nested JSON
