Michael Lawrence commented on SOLR-7414:
----------------------------------------
Is the CSV writing still maintained by anyone? Since this still has not been
assigned, I'm concerned about how well supported the CSV writing is. I would
give it a go myself, but it might be more practical for someone familiar with
Solr internals to address this hopefully minor issue.
