It cannot know what the "right" offset to be committed is. It's really the responsibility of the consumers to commit correctly. -Matthias On 7/27/23 1:03 AM, Vincent Maurin wrote: > Thank you Matthias for your answer, I open an issue on the aiokafka > project as follow up, let's see how we can resolve it there > https://github.com/aio-libs/aiokafka/issues/911 > > As mentioned in the issue, some tools like kafka-consumer-groups.sh > also display a lag of "1" in this kind of situation > > Best regards, > > Vincent > > On 13/06/2023 17:27, Matthias J.
