Ishan Chattopadhyaya commented on SOLR-7414:
--------------------------------------------
bq. I have this issue on my TODO list to investigate why there is specifically
an issue with CSV that is not also present with our other formats. Shouldn't
the code impacted for one format be essentially the same as the other formats?
It keeps slipping from my priorities so I'll simply ask it to everyone
following this.
AFAICT, the main difference between CSV/XLSX response writers and others is the
need for computing the header fields up front (for rendering a tabular output).
That, I believe, required this divergence in code paths and behaviour.
