Sami Peltola updated CAMEL-19972:
---------------------------------
Description:
h2. Expected behavior
* Should not matter if manual commits are enabled component level or endpoint
level, consumer should not commit automatically when autoCommitEnable is set to
false
h2. Actual behavior
The behavior for manual commits is inconsistent at the moment (Test on Camel
versions 3.18.5 and 3.21.1), depending on whether the KafkaComponent is
configured on component or endpoint level
* If configured on component level, will still automatically commit offsets
back to broker (after records from a partition have been processed)
* If configured on endpoint level, will never automatically commit offsets
* autoCommitEnable is
h3. Configuration of manual commit for Kafka client during startup
During startup for Kafka component, Camel context will go through the following
classes and methods while setting up manual commit configuration.
h4. KafkaComponent
[https://github.com/apache/camel/blob/camel-3.18.5/components/camel-kafka/src/main/java/org/apache/camel/component/kafka/KafkaComponent.java#L222]
*Class:* org.apache.camel.component.kafka.KafkaComponent
*Method:* doInit
* When the component is being initialized, will check if
configuration.isAllowManualCommit() is true AND kafkaManualCommitFactory is null
** If they are, will initialize kafkaManualCommitFactory as
DefaultKafkaManualCommitFactory
** If not, will leave kafkaManualCommitFactory as null
h4. CommitManagers
[https://github.com/apache/camel/blob/camel-3.18.5/components/camel-kafka/src/main/java/org/apache/camel/component/kafka/consumer/CommitManagers.java#L32]
*Class:* org.apache.camel.component.kafka.consumer.CommitManagers
*Method:* createCommitManager
* Called when initializing Consumer
** For clarity's sake, omitting Async-related logic
** If configuration.isAllowManualCommit() is true AND manualCommitFactory is
instance of DefaultKafkaManualCommitFactory
*** Will initialize SyncCommitManager
*** Otherwise, will initialize NoopCommitManager
h4. Summary
* Configuring manual commits on component level still results in automatic
commits when the changing partitions (or all records processed) since
*SyncCommitManager* is configured
h2. Workaround
* Configure manual commits on endpoint level
