Robert Muir commented on SOLR-3855:
-----------------------------------
Actually another idea is maybe there should be no default? And it wouldnt be
too bad if we combine docValuesType and docValues into one parameter.
So this way there is no trap (slow-io, or huge ram) on anyone. you would just
say docValuesType=packed docValuesMethod=(disk/memory?)
Then down the road once docvalues is really worked out, we could have example
fieldtypes for various use cases (id, sort, scoring factors, etc) configured
reasonably with whatever makes sense?
I guess it doesnt matter to me if there is a default, and what the default is,
as long as we are careful to both offer and advertise the ram/disk option in
the example (even if there is actually a default).
for this initial patch, we could just make it so only "memory" actually works
and you get a UOE if you ask for direct. I feel like this is a good step to
remove uninversion times, etc and we could separately add the disk option...
I'm just throwing out future ideas.

> 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).
