Jay Kreps commented on KAFKA-3824:
----------------------------------
[~beez] Sorry for not following up sooner. I think the reason for re-assigning
was probably that writing a complete description of the behavior in JIRA is the
same difficulty as just editing the javadoc directly.
I do think the description in the issue is fairly complete: The docs indicate
that we violate at-least once delivery when auto commit is enabled, but as of
0.10 we actually don't (i.e. our consumer delivery guarantees are stronger than
indicated in the javadoc). I'm not sure there is anything else to add to the
description.
In any case, sorry, we could probably have handled it more gracefully!
