> (sub-issue of SOLR-10117) This is a proposal for a better way for Solr to
> handle "large" text fields. Large docs that are in Lucene StoredFields slow
> requests that don't involve access to such fields. This is fundamental to
> the fact that StoredFields are row-stored. Worse, the Solr documentCache
> will wind up holding onto massive Strings. While the latter could be tackled
> on it's own somehow as it's the most serious issue, nevertheless it seems
> wrong that such large fields are in row-stored storage to begin with. After
> all, relational DBs seemed to have figured this out and put CLOBs/BLOBs in a
> separate place. Here, we do similarly by using, Lucene
> {{BinaryDocValuesField}}. BDVF isn't well known in the DocValues family as
> it's not for typical DocValues purposes like sorting/faceting etc. The
> default DocValuesFormat doesn't compress these but we could write one that
> does.
