Hi, if you use a new group for a consumer, the auto.offset.reset value will determine whether it will start at the beginning (with value earliest) or at the end (with value latest). For each group a separate offset is used, to two consumer, belonging to two different groups, when started before the producer, will both consume each message produced.
