Jay Kreps commented on KAFKA-2528:
----------------------------------
Yeah, sorry separate thought. What I'm trying to figure out is how closely can
we At first I was pointing out that the measurement didn't seem to match the
quota, and what I understood you to say was that we didn't really know what
that measurement meant in comparison to the quota metric and maybe it meant
something different so maybe the fact they don't match isn't a bug.
That's fine but then that doesn't really confirm the accuracy of the quota
enforcement either, right? So I was saying that my expectation would be if I
used the perf tests which do periodic throughput reporting that throughput
would match the quota I set (maybe off by a few percent but not like 10%). If
not I would think it was a bug.
