Hi lawlesm   ,
Thanks for reaching out to the Microsoft fabric community forum. 

Since the notebook is retrying around 30 times before it finally works, it might help to add some basic logging inside your notebook. You can log:

  • When each query attempt starts and ends
  • How many times it retries
  • The error message from each failed attempt

This can help you see if there’s a pattern, like increasing delays.

 

If I misunderstand your needs or you still have problems on it, please feel free to let us know.   

Best Regards,

    We have added logging and nothing looks out of sort besides what I posted above. MS is slow on tickets... So we copied our data out to a new lakehouse without OneLake Data Access enabled and we are back to normal. Something is awry.

       Hi  lawlesm  ,

      Thank you for the update, It’s good that moving the data to a Lakehouse without OneLake Data Access got you back to normal performance, but it definitely confirms something is off with the preview feature.

      Even though you’ve found a workaround, I’d still recommend keeping the ticket open with Microsoft so they can investigate and fix the root cause.

      Please refer below link on how to raise a contact support or support ticket.
