    [ https://issues.apache.org/jira/browse/CAMEL-10213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15401850#comment-15401850

Oliver Holzmann commented on CAMEL-10213:
-----------------------------------------

I missed that {{sessionTimeoutMs}} is already available. 

Only {{maxPollRecords}} missing.

> Currently it is not possible to control the processing time in the poll loop in Camel
Kafka consumers. 
> It is important to have the possibility to control the poll loop by adjusting {{max.poll.records}}
and {{session.timeout.ms}} . Otherwise this warning is produced when consuming a large backlog
from kafka topic:
> {code}
> Auto offset commit failed for group consumerGroup: Commit cannot be 
> completed since the group has already rebalanced and assigned the 
> partitions to another member. This means that the time between 
> subsequent calls to poll() was longer than the configured 
> session.timeout.ms, which typically implies that the poll loop is spending 
> too much time message processing. You can address this either by 
> increasing the session timeout or by reducing the maximum size of batches
> returned in poll() with max.poll.records.
> {code}
> Please add {{max.poll.records}} and {{session.timeout.ms}} to Kafka endpoint configuration.
