[jira] [Created] (CAMEL-8756) KafkaConsumer doesn't stop consuming
when suspended
André Stein created CAMEL-8756:
----------------------------------
Summary: KafkaConsumer doesn't stop consuming when suspended
Key: CAMEL-8756
URL: https://issues.apache.org/jira/browse/CAMEL-8756
Project: Camel
Issue Type: Bug
Components: camel-kafka
Affects Versions: 2.15.2
Reporter: André Stein
Hi,
we encountered a problem when consuming events from Kafka and stopping the route while there are still events in Kafka.
Obviously, the {{run}}-method doesn't stop reading events from Kafka stream and so there are always events in-flight what prevents the route from being gracefully shut down.
