You know, sometimes the simplest answer is the best. Just let the consumer do its thing and stop worrying about it. D) is a winner in my book.

True, it's always good to have a backup plan. B) sounds like a good solution in this case.

But what if we need to make sure the offset is committed? Maybe we should consider B) using the kafka-consumer-group command.

Restarting the consumer? That's like turning it off and on again, hoping the problem will magically go away. Nah, D) is the clear winner.

Haha, starting a new consumer group? That's like buying a new car every time you get a flat tire. Definitely not the solution here.

I agree, D) is the way to go. Manually committing offsets could cause more issues down the line. Let the consumer handle it from the last successful commit.

D) Nothing seems like the correct answer here. Since the broker never received the commit request for offset 2000, it's best not to interfere and let the consumer continue processing from the last committed offset of 3000.
