Problem Description

Hi,
I need to ability to commit offsets immediately when using sarama consumer group . Is there any way to do that?
Any plans to support it?

Thanks

Are you expecting MarkOffset functionality on consumer messages? This is supported:

I'm pretty sure author was referring to explicit commit, rather than just marking the offset internally. We would also like to have this feature!

I also want to submit an offset for each message I consume. When the program is suddenly interrupted, those who have consumed will not be consumed again, instead of submitting an offset at intervals of 'Config.Consumer.Offsets.CommitInterval'
