Adrien Grand commented on LUCENE-7590:
--------------------------------------
Instead of using a NOOP_COLLECTOR, you could throw a
CollectionTerminatedException, which will skip the segment entirely. By the
way, in such cases I think we should still increase the missing count?
Can we avoid making {{DocValuesIterator}} public?

> I think it can be useful to have DocValues statistics helpers, that can allow
> users to query for the min/max/avg etc. stats of a DV field. In this issue
> I'd like to cover numeric DV, but there's no reason not to add it to other DV
> types too.
