Which change can increase the performance of the Consumer Group?

NO.22 The Consumer property ‘auto offset reset’ determines what to do if there is no valid offset for a Consumer Group.
Which scenario is an example of a valid offset and therefore the ‘auto.offset.reset’ does NOT apply?

NO.23 You want to increase Producer throughput for the messages it sends to your Kafka cluster by tuning the batch size (‘batch size’) and the time the Producer waits before sending a batch (‘linger.ms’).
