Re: kafka-consumer-groups.sh CURRENT-OFFSET column show "-" , what mean about it ! thank you !

[Liam Clarke-Hutchinson]

Hi,

 It means the consumer group exists, and Kafka's aware of it's topic
subscriptions, but either the consumers haven't consumed yet (if using auto
offset commit) or the consumers haven't committed any offsets, if using
manual offset committing.

Does that make sense?

Kind regards,
