How many eventhub namespaces can I have?

IN https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-quotas, it said: across all tiers, Number of Event Hubs namespaces per subscription - 100

and then further down the same page, it said: Namespaces 50 per CU (dedicated tier)

Which is correct?

Thanks!

Solution

  • 100 namespaces per subscription is common to all tiers. You can ask this limit relaxed to 1000 via a support ticket.

    Dedicated tier has capacity enforced limit on top of the subscription limit mentioned above. Simply put, each Dedicated Capacity Unit allows 50 namespaces. So, say with 4 CUs, you can create 200 namespaces.
