Flavio Junqueira commented on KAFKA-3985:
-----------------------------------------
I've created a pull request for this, focused on this issue. KAFKA-4140 is a
broader set of changes, and it could incorporate the changes I'm proposing in
the PR. In fact, it seems to change it in a similar way.
It is still WIP, though, and might be better for the sake of seeing more green
in our builds to check this one in while we wait for KAFKA-4140, but I'm happy
with whatever folks prefer.
