Wait, retries=200000? That seems excessive!

A) max.in.flight.requests.per.connection=1 is also a good choice.

B) enable.idempotence=true, because who wants to deal with network-induced duplicates? Not this guy!

I'd go with B as well. Retries and batch size won't help with duplicate prevention.

Definitely B. Enabling idempotence is the way to go to prevent those pesky network-induced duplicates.

Batch size seems more about performance than duplicates, so I doubt D is correct. I’m really torn between A and B!

I feel like retries could help, but I don't think it's the right answer for preventing duplicates. So, I would lean towards B as well.

I'm not entirely sure, but I remember something about max in-flight requests affecting duplicates. Maybe A is relevant?

I think enabling idempotence is the key here, so I would go with B. It sounds familiar from our practice sessions.

B seems like the most straightforward solution. Enabling idempotence should do the trick.
