But what about A? Subscribing to the partitions could work too.

I don’t think converting the publishing app into a stream processor is correct. That seems like overkill for just consuming messages.

I’m a bit confused about whether the consumer group is necessary. I feel like it might help with load balancing, but I can't recall the details.

I remember practicing a question about Kafka consumers, and I think option C is definitely the right choice here.

I think the second application needs to subscribe to the Kafka topic, but I'm not entirely sure if it also needs to join a consumer group.
