Ken Giusti created DISPATCH-1643:
------------------------------------
Summary: Support auto link idle time out
Key: DISPATCH-1643
URL: https://issues.apache.org/jira/browse/DISPATCH-1643
Project: Qpid Dispatch
Issue Type: New Feature
Components: Router Node
Affects Versions: 1.12.0
Reporter: Ken Giusti
Fix For: Backlog
Use case:
Deployments that create and delete broker queues (accessed via auto-links) on
demand.
A service that creates auto-links to a broker when it connects. The auto-links
trigger the creation of a queue(s) on the broker. When the service shuts down
it removes the auto-links and thus deletes the queue(s) [dead lettering any
orphaned messages].
If the service should fail without cleaning up its auto-link/queue resources
the auto-link (and associated queue) will exist indefinitely.
Feature description:
Add an idle timeout attribute to the auto-link configuration. If the generated
link loses its router-side consumer(s)/producer(s) then after the idle timeout
expires the router should remove the auto-link configuration and teardown the
link. With the proper broker configuration this should result in the
corresponding queue being deleted and optionally any messages it contained
moved to a dead letter queue or simply discarded.
