> 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}
> {panel:title= Sidenode |borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE}
> 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.
