Gabriel Reid commented on CRUNCH-554:
-------------------------------------
[~jwills] or [~mkwhitacre], just wanted to double-check with you guys on the
idea of deprecating the numeric aggregators -- do either of you have any
preference on that in one direction or the other?
> Add min and max aggregators for Comparables

> In the Aggregators class, we currently have min and max aggregators for
> various numeric types, but not for the general case of Comparables. We do
> have this functionality in the MaxN and MinN aggregators, however.
> We should add MAX_COMPARABLES and MIN_COMPARABLES methods to the Aggregators
> class. As extra bonus, all of the current numeric max and min aggregators can
> be discarded and replaced with the comparable version.
