Yonik Seeley commented on SOLR-3855:
------------------------------------
Great stuff Adrien!
I think we should model the docvalues as stored fields (that's how I always
planned on doing it - but never got around to it). fl=* should still return
these fields. Think about optimistic concurrency, etc. Having to know all of
the field names to actually get all of the field values is not a good thing.
I wonder if we could pick a better name? "doc values" isn't very descriptive at
a higher abstract level. I always considered CSF/DocValues to be about storing
the values separately for better caching by the OS. "stored separately" seems
closer to the real description. One thing to consider is that even if Lucene
changes the names of the methods later, we try to stick with external APIs
longer in Solr - hence it can be less important that the names exactly match
what is in lucene and more important that they are something we want for the
long haul.

> It would be nice if Solr supported DocValues:
> - for ID fields (fewer disk seeks when running distributed search),
> - for sorting/faceting/function queries (faster warmup time than fieldcache),
> - better on-disk and in-memory efficiency (you can use packed impls).
