Yonik Seeley commented on SOLR-8740:
------------------------------------
I think it's a good idea... there is a lot of performance to be gained out of
using docValues when returning a couple of docValue fields for many documents
(like the export handler currently does). Although we *can* (and should at
some point) have docValue implementations that preserve order, we don't have
them yet... and the note leaves the door open to implementing optimizations
before the next major release.
> set docValues="true" for most non-text fieldTypes in the sample schemas

> We should consider switching to docValues for most of the non-text fields in
> the sample schemas provided with solr.
> This may be a better default since it is more NRT friendly and acts to avoid
> OOM errors due to large field cache or UnInvertedField entries.
