> ??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 thread.
>
> This needs to be investigated further.
