>But the closest I ever came to using a functionally developed product was RabbitMQ (written in Erlang). That one was _such_ a pain to use and operate — must have been the developers still dreaming in the purity of its code instead of writing some installation docs. I moved on to Kafka later and didn't regret it a minute.

Err, RabbitMQ is one of the easiest to setup and stabler queues/messaging systems. And I'm no user/fan of Erlang...

I found Kafka easier to set up. RabbitMQ is a bit finicky when it comes to config, monitoring, administration, but it's pretty okay, and works well enough if you really need AMQP semantics (selective ack of messages).
