If I need to include 105 topic templates in my Azure Event Grid Namespace, Do I need more AEG namespaces?

Question

I currently need to provide 50 topics that relate to data from Server to Client, and 55 topics that relate to Client to Server communicaiton in Azure Event Grid MQTT Broker.

If each namespace allows 10 topic spaces, and each topic space allows 10 topic templates. I would be 5 topics short of meeting my requirements. In this case, should I create additional AEG Namespaces? Is there a better way to design this?

Hello @Andrew Wilson,

welcome to this moderated Azure community forum.

Yes, as seen in the documentation, there are limitations to both the number of Topic spaces, and Topic templates:

But a topic template is not limited to one topic:

You can add multiple topics.

As an alternative, you could try to use a wildcard to support a whole group of sub topics using the '#' or '+' together with the topic separators.

If this doesn't help, create a support ticket and explain to Microsoft why you need extra topics. They are always interested in real-world use cases.
