Federation Throughput MQTT Exchange -> SuperStream

[Rilind Harizaj]

Hello all,

I am new to federation, and I was wondering how efficient a federation link between an upstream MQTT Exchange and a downstream superstream would be. 

I am trying to compare this approach as compared to implementing a client application that routes the messages from the MQTT exchange (by subscribing to the topics) to a super stream in another RabbitMQ Cluster.

Any idea/information would be highly appreciated.

Best

Hi Rilind, community guy here.

As you could imagine I don't think there's anything besides networking overhead. The Federation is basically an (internal) AMQP client (as described https://www.rabbitmq.com/docs/federation#link-failures)

If go via Federation you will only have network-hops between connected Rabbit instances where as deploying your own application would be adding +1 extra network hop into the mixture - depending on which network you are deploying this WAN vs LAN this can a huge difference (honestly even LAN?).

I would recommend benchmarking this but I personally would chose for Federation unless you having more control is an requirement.
