- With same consumer group, you can't have consumers more than the number of partitions. Even if you do, extra consumers are just idle. Each partition can be read only by one consumer. - With different consumer groups, you can have as many consumer groups as you want for a single topic. Each consumer group will have its own offset management. Each consumer group will get all messages - meaning 2 different consumer groups will receive the same number of messages if subscribed to the same topic.
Hope that answers your doubt.
