Claus Ibsen resolved CAMEL-10944.
---------------------------------
Resolution: Fixed
> camel-kafka - When consumer stop it should auto commit
> ------------------------------------------------------
>
> Key: CAMEL-10944
> URL: https://issues.apache.org/jira/browse/CAMEL-10944
> Project: Camel
> Issue Type: Improvement
> Components: camel-kafka
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Fix For: 2.19.0
>
>
> When you do a graceful stop of a Kafka route you should be able to auto
> commit so the offset is up to date on the broker, so any new consumer that
> failover, or if you start the route again, it will pickup from the right
> spot. Otherwise you have duplicates.
> The kafka consumer will auto commit in the background every 5th sec but if we
> dont explicit auto commit on stop then we only have the last offset from the
> last background thread run and therefore have much higher chances of
> duplicates.
> We should add option so users can control if auto commit on stop is
> sync,async,none
> We should do sync so its forced in case its the JVM shutting down and we cant
> do async in the background. And ppl can set it to none if they want as it is
> today
