Subject [jira] [Commented] (CRUNCH-554) Add min and max aggregators for Comparables
Date Sat, 01 Aug 2015 07:35:04 GMT

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.
