Azure Servicebus Topic Subscription competing consumers affected by PrefetchCount

Hope this helps Both queues and subscriptions support the competing consumers in the same way. Prefetch is what not working the way you might expect. When you ask to prefetch N items, the broker will not distribute those evenly among the competing consumers. Rather will try to give each consumer as much as it can. So if you have 10 messages and set the prefetch to 10, the first consumer might get it all leaving nothing to handle to the second consumer.

SqlFilter on Azure ServiceBus Topic subscription not filtering

Hope that helps When you create a Subscription then by default you get a "MatchAll" filter. In the code above you are just adding your filter so it is applied in addition to the "MatchAll" filter and thus all messages are recieved. Just delete the $Default filter once the Subscription is created and that should resolve the issue.

Can I View the Filters Currently Enabled on an Azure ServiceBus Topic Subscription?

This might help you Yes, you can get list of rules for a specific topic and subscription through NamespaceManager.GetRules(string topicPath, string subscriptionName) :
code :
        var rules = namespaceManager.GetRules("MyTopic", "MySubscriber");
        foreach (var ruleDescription in rules)
        {
            Console.Write(ruleDescription.Name);
            var filter = ruleDescription.Filter;
        }

How to use a ServiceBus Trigger with a topic/subscription in an Azure Function

it helps some times Yes topics are supported, but our UI and templates are behind on that unfortunately - we'll be releasing some updates soon addressing these issues.
For now, you can use the Advanced Editor to edit your trigger binding directly. There you can specify your subscriptionName and topicName values. Here's an example:
code :
{
  "bindings": [
    {
      "type": "serviceBusTrigger",
      "name": "message",
      "direction": "in",
      "subscriptionName": "subscription-test",
      "topicName": "topic-test",
    }
  ]
}

Azure Service Bus topic and subscription design for microservice-type consumers


By : A Katsiamakas

With these it helps When deciding about a topology, take into consideration things that matter to you the most. One of the principles of pub/sub is to decouple between publishers and subscribers. With topology #2 (topic per publisher) this principle is violates since every subscriber would have to know the name of the publisher. And if publisher of an event would change, all your subscribers would have to get that knowledge in order to re-subscribe. Topology #1 solves that problem by abstracting publishers away by using a single topic.
Also, the 2nd requirement you had (to audit all of the events) would be much easier to implement with this topology as you only have to maintain a single wiretap subscription on that topic.

How to Determine Azure ServiceBus PrefetchCount and ReceiveBatch Size

This might help you
I don't really understand how to determine the receiver's "messages per second" when the batch retrieval seems to retrieve widely-varying numbers of messages at a time.
