Support for Unity Catalog External Data in Fabric OneLake

[MariusE]

Hi community!

We have set up a Fabric Link with our Dynamics, and want to attach the data in Unity Catalog using the External Data connector.

But it doesn't look like Databricks support other than the default dls endpoints against Azure.

Is there any way for us to resolve this?

The error we get when trying to connect is:

Failed to access cloud storage: [AbfsRestOperationException] () exceptionTraceId=XXX

The URL to Fabric is:

abfss://<guid>@onelake.dfs.fabric.microsoft.com/<guid>/Tables/account

I have tried linking to the root folder to, without success.

Any help is much appreciated.

Hi @MariusE ,

OneLake is not supported yet in Unity Catalog, that's why it's not working in this case.

Connect to cloud object storage using Unity Catalog - Azure Databricks | Microsoft Learn

Thanks @szymon_dybczak , do you know if support is on the roadmap? 

Since the current supported way of doing this with credential passthrough on the Compute is deprecated.

Hi @MariusE ,

Unfortunately, I have no idea. Maybe some databricks employee will kick in and shed some light on this topic
