EventStream Questions

how can I get the EventStream's source from the Delta table in the Lakehouse? or from the API? it seems limited to only those 2?

And when I want to connect to the Data Source, it says:

and when I click Continue, it mentions that I don't have permission to access this resource.

Hi @tan_thiamhuat ,

Your screenshot shows a message: “You need to verify your identity”, followed by “You don’t have permission to access this resource." typically means :

If you're using a service account, it may not be allowed to perform interactive logins or access certain resources directly.You may need to submit an exception request for interactive login via the EGRC portal.
Verify your license and role assignment in the Power Platform admin center.
Use OneLake shortcuts to expose Delta tables to SQL endpoints

Hope this helps!

The message seems to a login issue, if you logout and then logout, mostly it will solve the issue. Its not a access issue. If I am getting you correct, you are trying to stream delta tables(lakehouse tables) which is not supported yet, if u have data in azure data explorer you can then stream it using eventstream.
Once you click on "New source" -> "Connect data sources", a list of sources can be seen.
One point to note here is, eventstreaam will consume lot of CUs which can be bottleneck in future. As suggested by @v-sdhruv , shortcut can be good option to explore.

Please let us know if you have any further doubts or clarification required, I would be happy to help.

Hi @tan_thiamhuat

Here the source of the onelake is OneLake events. You can see the source here in my Microsoft Fabric
