[VOTE] KIP-799: Align behaviour for producer callbacks with documented behaviour
Hi everyone,
I'd like to start a vote for KIP-799: Align behaviour for producer
callbacks with documented behaviour
<https://cwiki.apache.org/confluence/display/KAFKA/KIP-799%3A+Align+behaviour+for+producer+callbacks+with+documented+behaviour>
.
The KIP proposes a breaking change in the behaviour of producer client
callbacks. The breaking change would align the behaviour of callbacks with
the documented behaviour for the method, and makes it consistent with
similar methods for producer client interceptors.
Regards,
Séamus.

Hi Kirk,
Thanks for bringing this to my attention! I hadn't found KAFKA-12841
previously, and so I had created KAFKA-13448 (a duplicate issue) and an
associated PR back in November. I was told to create a KIP as it was a
change in behaviour, and that's the reason for this KIP.
PR #11689 implements this KIP and is already merged, so I guess there's now
no need to continue this vote...
Regards,
Séamus.

Hi Seamus,
Is there a conflict between KIP-799 and KAFKA-12841 <https://issues.apache.org/jira/browse/KAFKA-12841>? A related fix for the latter issue was just merged a few days ago (https://github.com/apache/kafka/pull/11689) and it seems like there's some overlap or discrepancy between the two.
Thanks,
Kirk

Hi all,
Bumping this thread again.
Kind reminder that* this KIP addresses a* *bug in the Kafka producer client*,
where the implemented behaviour of the producer client is not the same as
the documented behaviour in the case of callbacks. This has caused
production incidents 'in the wild'.
Regards,
Séamus.

Hey Luke,
Thanks for the feedback. I've updated the relevant section to hopefully
make it more clear from the KIP itself what placeholder value would be
returned.

Hi Séamus,
Thanks for the KIP!
We definitely want to keep the producer callback consistent for all types
of errors.
Just one comment for the KIP:
In the "Proposed Changes" section, could you please "explicitly" describe
what placeholder you'll return, in addition to adding a hyperlink to other
places, to make it clear.
+1 (non-binding)
Thank you.
