Oh boy, this is a long topic. To mention a few issues:
1) Resource usage is pretty much unlimited for an AMQP client.
(consider creating 1M queues, sending tremendous amount
of durable messages or opening 65K channels)
2) The security model of AMQP is inadequate for the browser
world, where the browser is basically untrusted.
3) The protocol is overcomplicated for the browser needs. Do you
I personally think the fact that AMQP is assuming trusted
clients, and on the web the opposite is true, is basically
a show stopper.
STOMP doesn't solve all this issues (security model
is similar, for example), but at least it's way simpler
to reason about. (lack of channels is one example of that)
In my ideal world the RabbitMQ-web-stomp would be
limited to only consuming messages, to avoid problem
mentioned in 1), but this would limit its functionality
too much, so we decided not to pursue this.
