Description:

Hi,

I have a nservicebus based endpoint which is hosted on azure as a worker role. We use ASB as the transport and this is a receiveonly endpoint. We are trying to see if there is a option to listen to an event that can be sent from two different namespaces. For reasons of High Availability, the event publisher will publish events in ASB namespace1  and in ASB namespace 2. The receiver needs to listen to both the ASB subscriptions. Is this possible to achieve with INamespacePartitioningStrategy ?

[Sean Feldman]

You're are correct.

The simplest way in this case would be to use RoundRobinNamespacePartitioning strategy provided OOTB.

[Haripraghash Subramaniam]

Ok. These strategies sound like they work on Partitioned queues and topics. If the topics are not partioned then these sytartegies dont work? Is there a way to subscribe to say a primary namespace and a secondary namespace at the same time and keep listening to them both?

[Sean Feldman]

This is what topology strategies should do OOTB.

Thank you for raising an issue. We'll have a hotfix and that should let you achieve what you need.
