Michael McCandless commented on LUCENE-5476:
--------------------------------------------
I don't think we need a sampling package (overkill), and I also don't think we
need a separate "config" class (SamplingParams/Config) which will bring
complexity/questions itself; I think it's a non-goal here to revive the
previous sampling implementation with all of its complexity, nor to push all of
this responsibility onto Rob, who's doing great work here.
Rather, I think we should start simple (what Rob needs, here), commit that, and
iterate from there, bringing back features as users need them.

> With LUCENE-5339 facet sampling disappeared.
> When trying to display facet counts on large datasets (>10M documents)
> counting facets is rather expensive, as all the hits are collected and
> processed.
> Sampling greatly reduced this and thus provided a nice speedup. Could it be
> brought back?
