In the case of queues in the standard address space you don't know where your queue is, how many storage units (i.e. Brokers) the queue is sharded across. The implementation may move a queue between storage units during its lifetime for efficient resource utilisation. It may not necessarily be hosted on a Broker.... Exposing the underlying APIs would be an obstacle when offering these higher level behaviours.</div><div><br></div><div>Tell us about your use-case for for diverts?
