How to delete event streams properly

[Sandra_h710]

We had some tests with the Activator and event streams to detect new file creations in the Azure Blob container. However, even after deleting the items and had deleted the Event Grid System Topic in Azure, they still appear to be running in the background, as observed through the Fabric Capacity Monitor. Does anyone know the correct way to fully terminate them and restore the capacity back to us? Thanks .

Hi @Sandra_h710 

Even after you delete the Azure Event Grid topic, the Event Stream and Activator objects you created in Fabric continue to run in the background until they’re removed from the workspace.
To fully terminate them and free up your capacity:

1. In the Fabric portal, open your workspace and go to Data Factory → Event streams. Find each stream (for example “Test001” or “BLOB_EVENT_MONITOR”), click the ellipsis next to its name, and choose Delete.

2. Still under Data Factory, switch to Activators, locate “BLOB_EVENT_ACTIVATOR,” click the ellipsis, and select Delete.

3. Wait five to ten minutes for Fabric to shut down the background processes, then refresh your Capacity Monitor; the CU and Duration figures for those items should drop to zero.

4. (Optional workaorund) In the Azure portal, delete the corresponding Event Grid System Topic and any related subscriptions to stop any remaining events from reaching Fabric.

Once both the Event Stream and Activator definitions are removed from Fabric—and the Azure topic/subscription is deleted—the Capacity Monitor will no longer list or bill for those executions.

If this resolves your issue, please give us Kudos and mark this response as Accepted as solution.

Hi Csrikanth,

Thanks for sharing the deletion steps. When I deleted the items, I recall deleting the first EventStream which was called test001 and deleted right after it was created successfully.   Then I had created one EventStream and one Activator in the Dev Workspace. When I identified the capacity issue, I deleted the EventStream first, followed by the Fabric Activator. However, I didn’t wait for 5 minutes between each step. It appears that these background items were still running. After identifying this, I attempted to delete the items in the Azure Event Grid Subscription, but unfortunately, it didn’t resolve the issue. The background event listener is still active and consuming Fabric capacity. We’ve already reached out to Microsoft Support regarding this matter. Thanks for following up on this. It would be really helpful if the deletion steps could be included in an official Microsoft document for future reference.

Best regards,

Sandra
