Is it possible to use Queue instead of Topic for certain messages in ASB?

[Arik-Shapiro]

I want to be able to use Queues for Commands and Topics for events.
Is it possible to control whether the library uses a queue for a certain messages or a topic?

Thanks.

Would you be able to provide a little more background as to your use case @Arik-Shapiro? As a general rule you wouldn't send a command onto a queue except in particular circumstances.

However, as I understand it although generally topics are used to for allowing multiple subscriptions to that queue and all get a copy of that message, there is nothing stopping you only having one subscription to that topic? So the service that needs to receive command can be the only one that subscribes to that topic.

So if we understand a little more about your use case we may be able to advise better, or raise an issue for changes.

@Arik-Shapiro to summarize, you want use queues to integrate with what you already have in your environment?

@preardon
Yes.
Sorry I may have exaggerated with the details 😄. Wasn't sure if you were asking about commands in my case or just why I wanted to use queues for them.

@Arik-Shapiro I am more than happy to talk to you about commands / events. I feel what you are describing about is more of an event not a command but that's not the point of your request.

In terms of ASB transport, I'm happy for changes to be made to support Queues as well I think we would need a Bool on ASB subscription to select an the way in as well as one of ASB Public to do the same. Also we would want to ensure intergration tests for queues as well

@preardon
Glad to hear! Should I make a feature request?

[preardon]

@Arik-Shapiro Please do, and let me know if you want a chat about design before you get started on the PR :)
