This shouldn't happen. I can see why it might happen and we will create a JIRA and fix it right away. I'm not sure how you end up with (hello -> 10). It could indicate that the offsets for the topic you are consuming from weren't committed so the data gets processed again on the restart. Thanks, Damian
