Hold up, did someone say 'exactly once'? That's like a unicorn in the world of distributed systems! Good luck getting that to work in the real world. I'll just take a wild guess and go with C.

I think it's A) Kafka => Kafka.

I'm going to have to go with option B. The exactly once guarantee is for the Kafka => External flow, where you want to make sure your downstream systems receive each message exactly once, without any duplicates.

Hmm, I'm not so sure about that. Doesn't the exactly once guarantee apply to the External => Kafka flow as well? I mean, you want to ensure exactly-once processing of data coming from external sources, don't you?

I believe the exactly once guarantee is for External => Kafka flow, as it ensures data consistency when bringing in external data.

I think the exactly once guarantee in Kafka Streams is for the Kafka => Kafka flow of data. That's the whole point of the Kafka Streams API, right?

I agree with Ora, because Kafka => Kafka ensures no data loss or duplication.
