-----------------------------------
Summary: 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
