RabbitMQ + STOMP - can I create durable queue on subscribe?

Question

Can I make RabbitMQ 3.4.1 create new DURABLE queue named "q123" when a STOMP client sends

SUBSCRIBE
destination: /amq/queue/q123
...

and use this queue for later subscriptions ?

Answer 1

You can't create new queue outside STOMP gateway. You can SEND and SUBSCRIBE them, but not create new one.

STOMP may create it for you if you will refer to /queue/<your-queue-name> in vhost specified by your STOMP plugin settings (by default it is standard / vhost).

So such STOMP frame will create new-random-one durable queue in / vhost.

SUBSCRIBE
destination: /queue/new-random-one

Here is how to run it over raw shell (^@ stands for Ctrl+@, empty line before it matters):

nc localhost 61613
CONNECT

^@
CONNECTED
session:session-3IE6yYjn6borQ_4KLfxLMw
heart-beat:0,0
server:RabbitMQ/3.4.1
version:1.0

SUBSCRIBE
destination: /queue/new-random-one

^@
DISCONNECT

^@

So after that, even after disconnected, you'll see that new-random-one queue will still reside in default vhost.
