Robert Muir commented on SOLR-3855:
-----------------------------------
I like the size of this patch!
One thing thats a little confusing is the multivalued check against a boolean
'hasDocValues'.
In lucene this is not a limitation of docvalues per-say, instead its
controlled-per-type. it just happens that all 3 types today have consumers that
check for this and throw exception, but we might add a multi-valued type later
(LUCENE-4765).
Separately there is also the possibility that someone can lay down their own
multi-valued encoding over e.g. a binary dv (like lucene facets/). But if we
have a private check called from SchemaField's ctor and checks in e.g.
DocumentBuilder, it seems like this would be difficult to change. Maybe as a
start we should just let IndexWriter handle the check here?

> 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).
