Robert Muir commented on SOLR-10273:
------------------------------------
This is a big deoptimization for the common case... Lucene must preserve field
order and you lose compression if its inconsistent across docs. Also bulk
merging relies upon field number consistency across segments. IW tries to keep
them aligned but this patch os intentionally being adversarial... To benefit
what is a rare and esoteric case.
This kind of thing should be only enabled by an option.

> (part of umbrella issue SOLR-10117)
> In Solr's {{DocumentBuilder}}, at the very end, we should move the field
> value(s) associated with the largest field (assuming "stored") to be last.
> Lucene's default stored value codec can avoid reading and decompressing the
> last field value when it's not requested. (As of LUCENE-6898).
