Hi Vahid,
+1 wrt OffsetFetch.
The "Additional Food for Thought" mentions Heartbeat as a non-mutating
action. I don't think that's true as the GroupCoordinator updates the
latestHeartbeat field for the member and adds a new object to the
heartbeatPurgatory, see completeAndScheduleNextHeartbeatExpiration()
called from handleHeartbeat()
NB added dev mailing list back into CC as it seems to have been lost
along the way.
Cheers,
Michał

Hi Colin,
Thanks for the feedback.
To be honest, I'm not sure either why Read was selected instead of Write
for mutating APIs in the initial design (I asked Ewen on the corresponding
JIRA and he seemed unsure too).
Perhaps someone who was involved in the design can clarify.
Thanks.

Permission of OffsetFetch
Hi Vahid,
I think you make a valid point that the ACLs controlling group
operations are not very intuitive.
This is probably a dumb question, but why are we using Read for mutating
APIs? Shouldn't that be Write?
The distinction between Describe and Read makes a lot of sense for
Topics. A group isn't really something that you "read" from in the same
way as a topic, so it always felt kind of weird there.
best,
Colin

OffsetFetch
Hi,
I started a new KIP to improve the minimum required ACL permissions of
some of the APIs:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-163%3A+Lower+the+Minimum+Required+ACL+Permission+of+OffsetFetch
The KIP is to address KAFKA-4585.
Feedback and suggestions are welcome!
Thanks.
