-------------------------------------

             Summary: Camel KafkaConsumer should be able to re-consume the 
Kafka stream.
                 Key: CAMEL-9716
                 URL: https://issues.apache.org/jira/browse/CAMEL-9716
             Project: Camel
          Issue Type: New Feature
          Components: camel-kafka
    Affects Versions: 2.17.0
            Reporter: Sebastian Rühl
            Priority: Minor


In some corner cases we should be able to re-consume a Kafka stream from the 
beginning on startup of the endpoint.
For this the Kafka-KafkaConsumer has a method
{code:java}
   public void seekToBeginning(TopicPartition... partitions) {
{code}

There are other methods to manipulate offsets but for this ticket we just look 
on the re-consume corner case.
{panel}

Currently I have implemented this support in a branch here 
([https://github.com/sruehl/camel/tree/feature/kafka-seek-support]) and have 
also written an jUnit test.
At this time this test still fails for unknown reasons.

I would be keen on some feedback on this feature and also would like to advance 
this branch to make it mergable.
