So let me get this straight. You've used Kafka once, RabbitMQ never. You don't really know what you did with Kafka. But you somehow know that RabbitMQ cannot do the thing which you don't really remember anymore. Doesn't make much sense to be honest.

Nobody can really have any sources for RabbitMQ being able to do it if you don't know what it supposedly cannot do. The way you descibed it, is that you simply read data and then did something with the data and passed it to somewhere else. RabbitMQ obviously can do it.
