Why Kafka don't allow multiple consumers within Same Group to consume messages from same partition?

[@shreyas-s5g]

sir as you said that, there is no point in adding more consumers in a single group than no of partitions...what my doubt is if we add an extra or couple more as backup consumer so that if any consumer goes down then that xtra could add up to service, thus maintaining the stability as earlier. ?? is it better to add xtra consumers as backup. #kindly reply _/\_ sir
