Hi, in the documentation about AMQ clustering on OCP, we state that
durable subscriptions are not supported and the reasoning makes sense,
but what about using NodePort? I haven't tried yet, but in this case I
would expect to work as in a standalone cluster because external
clients are connecting directly to broker pods. Any comments?
