It shouldn't.
Creating several listener / consumer processes belonging to the same group means you are working with a point-to-point message channel so incoming messages will be delivered only to one consumer.

Maybe I'm wrong but I believe in that scenario there's no difference (from broker perspective) between threads and processes.

Hi,

Does Kafka have a limitation on the simultaneous connections (created with
Consumer.createJavaConsumerConnector) for the same topic within the same
group?

My scenario is I need to consume a topic from different process (not
thread), so I need to create lots of high level consumers.
