Doc Text:	Auto-deleted queues are useful for preventing stale queues. However without some delay on the deletion, they prevent any reliability as the queue is lost as soon as a subscriber is disconnected, which may be due to some failure condition. A delay can be configured between the time a queue becomes eligible for auto-deletion and the time the deletion actually occurs. By configuring a queue with a non-zero autodelete timeout, a subscriber of the queue can re-subscribe after a failure (providing the subscriber does so within the configured limit) and not have messages lost along with the queue.

Description Petr Matousek 2013-07-18 12:03:37 UTC

Description of problem:

Defining durable subscription queues to be auto-delete by default without a delayed time for the auto-delete do not make much sense.

It would be valuable to define a configurable time-delayed auto-delete that will be applied to subscription queues by default. This will protect the broker from clients that go off and leave stale subscriptions after a crash, but it still retain the general ability to survive a crash and re-establish subscription without lost messages.

Version-Release number of selected component (if applicable):
qpid-cpp-*-0.22-7

How reproducible:
n/a

Steps to Reproduce:
n/a

Actual results:
subscription queues are auto-delete by default when declared over amqp0-10
subscription queues are *not* auto-delete by default when declared over amqp1.0

Expected results:
subscription queues are *not* auto-delete by default when declared over amqp0-10 (see bug 985869)
There is a configurable time-delayed auto-delete applied on subscription queues by default.
