publish subscribe - Auto-expire orphaned Subscription (Azure ServiceBus Messaging SubscriptionClient)

Question

The scenario I have in mind is this: Service Bus is used for instance-to-instance communication, so a Subscription is unique per service instance. The end result is that if an instance does not shut down gracefully, its subscription does not get deleted.

When a service instance "dies" and restarts, previous contents of the subscription are irrelevant and can be discarded.

So, is there a way to set a "time to live" for Service Bus Subscription or simulate something similar, without having to resort to some custom orphan detection mechanism?

Answer 1

Starting with Azure SDK 2.0 this works as expected.

Also, contrary to other reports, in my testing, subscription does not get deleted as long as there is a pending receiver listening to that subscription.

var description = new SubscriptionDescription(topicPath, subscriptionId);
description.AutoDeleteOnIdle = TimeSpan.FromSeconds(600);
namespaceManager.CreateSubscription(description);
