Michael McCandless commented on LUCENE-7589:
--------------------------------------------
bq. However if you add a new field that stores the average number of miles per
hour as a long doc values field, then it highlights the quality issues of this
dataset and disk usage for this field goes from 40 to 15.7 bits per value
(-60%) with the patch.
Ahhh, I see! The taxis that go faster than the speed of light are not apparent
now since we don't store that field directly... makes sense.
> Prevent outliers from raising the number of bits of everyone with numeric doc
> values

> Today we encode entire segments with a single number of bits per value. It
> was done this way because it was faster, but it also means a single outlier
> can significantly increase the space requirements. I think we should have
> protection against that.
