Derek Troy-West commented on KAFKA-13598:
-----------------------------------------
Very happy to [~showuon] I will just copy points 1-4 into the notes if that's
ok?
I'll raise a PR later this afternoon. Should I raise that PR on the apache-site
github repository?
> idempotence producer is not enabled by default if not set explicitly
> --------------------------------------------------------------------
>
> Key: KAFKA-13598
> URL: https://issues.apache.org/jira/browse/KAFKA-13598
> Project: Kafka
> Issue Type: Bug
> Components: clients, config
> Affects Versions: 3.1.0, 3.0.0
> Reporter: Luke Chen
> Assignee: Luke Chen
> Priority: Major
> Fix For: 3.0.1, 3.2.0, 3.1.1
>
>
> In KAFKA-10619, we intended to enable idempotence by default, but this was
> not achieved due to a bug in the config validation logic. The change from
> acks=1 to acks=all worked correctly, however.
> This is the following up for KIP-679:
> [https://cwiki.apache.org/confluence/display/KAFKA/KIP-679%3A+Producer+will+enable+the+strongest+delivery+guarantee+by+default]
>
> Note: In KAFKA-13673, we'll disable idempotent producer when
> acks/retries/max.in.flight config conflicts, to avoid breaking existing
> producers.
