Brandon Williams commented on CASSANDRA-820:
--------------------------------------------
Discussed with Jonathan on irc, and we decided to keep this as-is since the key count can be falsely inflated via the op count when the last range slice returns less than the specified count.

--------------------------------------------
Yes, now that you mention it, that makes the most sense. I'll rework the patch to remove op counts.

---------------------------------------------------------------------
It's worth noting that during reads/inserts you would expect the op rate to be equal to the key rate, but this isn't always the case due the concurrent processes involved, however they should always be fairly close. Key rate has no real meaning during these operations anyway, it is only included so that that the output format is consistent between all the operations.

This patch adds an interval_key_rate to all operations, and fixes a small bug in rangeslice when the length of the result is one.

------------------------------------------
somehow i thought we were only outputting key rates. oops.
i'd be fine w/ leaving it just outputting op rates... now that the code is written, what do you think? :)
