--------------------------------------------
Summary: camel-kafka: investigate offset not increasing
Key: CAMEL-18717
URL: https://issues.apache.org/jira/browse/CAMEL-18717
Project: Camel
Issue Type: Bug
Components: camel-kafka
Affects Versions: 3.18.3
Reporter: Otavio Rodolfo Piske
Assignee: Otavio Rodolfo Piske
Quoting the report from an user on the users mailing list:
??Hi All,??
??I'm upgrading Camel from 3.16 to 3.17 and found a problem that
OffsetRepository didn't get update after manual commit.??
??It is a Spring boot project and MemoryStateRepository as follows.??
?? @Bean??
?? public MemoryStateRepository offsetRepo() {??
?? MemoryStateRepository stateRepository = new
MemoryStateRepository();??
?? stateRepository.setState(topic + "/0", "");??
?? return stateRepository;??
?? }??
??Here is the method I use when commit:??
?? private void commitOffsetToKafka(Exchange exchange) {??
?? KafkaManualCommit manual =
exchange.getIn().getHeader(KafkaConstants.MANUAL_COMMIT,
KafkaManualCommit.class);??
?? manual.commit();??
?? }??
??Here is my Kafka endpoint??
??kafka:integration_test
_topic?brokers=[127.0.0.1:41478|http://127.0.0.1:41478/]&autoCommitEnable=false&allowManualCommit=true&seekTo=beginning&maxPollRecords=2&groupId=ANE&autoOffsetReset=earliest&offsetRepository=#offsetRepo&kafkaManualCommitFactory=#class:org.apache.camel.component.kafka.consumer.DefaultKafkaManualCommitFactory??
??It is working fine in 3.16. When DefaultkafkaManualSyncCommit.commit() is
invoked. The offsetRepository.setState() get invoked so the offset increased.??
??However, in 3.17, DefaultkafkaManualSyncCommit.commit() doesn't have a
reference to offsetRepository so the offset in offsetRepository won't get
increased.??
??Is this a bug or there is a different way to get the offset after committing.
Could you please suggest what I should do to test if the offset get increased
after manual commit???
This happened even after upgrading to Camel 3.18.3 as requested on the ticket.
This needs to be investigated further.
