> camel-kafka - KafkaIdempotentRepository misses continuous updates from its
> topic after startup
> ----------------------------------------------------------------------------------------------
>
> Key: CAMEL-20682
> URL: https://issues.apache.org/jira/browse/CAMEL-20682
> Project: Camel
> Issue Type: Bug
> Components: camel-kafka
> Affects Versions: 4.4.0, 4.4.1, 4.5.0
> Reporter: David Horn
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 4.x

>
> With CAMEL-20218 and CAMEL-20373 the initialization of the
> {{KafkaIdempotentRepository}} has been changed and seems to work fine.
> One purpose of a {{KafkaIdempotentRepository}} is to synchronize an
> idempotence state over multiple processes (running in parallel on potentially
> different machines). So a key feature of a {{KafkaIdempotentRepository}} is
> the continuous update of the local in-memory cache with add/remove events
> from the idempotent repository's topic *after initialization*. With Commit
> [a407fd82512e6680f4d6d6f97d836e63f76029e6|https://github.com/apache/camel/commit/a407fd82512e6680f4d6d6f97d836e63f76029e6?diff=split&w=0#diff-8a2c6e5db1f384f93ecfc83f27b90f633d97c0a43775c0b44a75d88b1b74613f]
> this capability got lost.
> I absolutely hope this happened unintentionally and will be fixed soon.
> +Side Note+
> I was surprised to see, that consuming from the idempotent repository's topic
> worked without providing a consumer group even though we have Kafka's access
> control activated, restricting describe/read access of this topic to
> dedicated consumer groups only.
