<p>Here is some confusion I have met.</p>
<p>For example, I have two event hub namespaces named A and B. A and B both contain a topic called C.</p>
<p>I want to know :</p>
<ol>
<li>if I delete C in namespace A, will it affect namespace B?</li>
<li>if I delete namespace A, will it affect namespace B?</li>
</ol>
<p>Thank you.</p>

<p>What you do in one Azure EventHub namespace doesn't affect another namespace, each namespace provides a &quot;unique scoping container&quot; (including deleting a namespace).</p>
<p>Each Azure EventHub namespace (like a &quot;folder&quot;) can contain many eventhubs (like &quot;files&quot; inside the parent &quot;folder&quot;), here is a good doc to get familiarized with the concepts: <a href="https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-features#namespace" rel="nofollow noreferrer">https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-features#namespace</a></p>
<p>Unless you specifically deployed an app or configured some sort of forwarding/connection between eventhubs (&quot;C&quot; in your case), there's no impact from deleting &quot;C&quot; from &quot;A&quot; unto &quot;B&quot; (or viceversa) by default.</p>
