DataFlow timeouts

Hi all, I hope someone can shed some light here. It's been a week since most of our Dataflows fail to refresh with timeout, after 2 hours. It's not a database timeout issue, as someone would guess....

    Hi philosopher ,

    Engineering team have fixed the Power BI Known issue : Some Dataflow refresh fails with timeout error when enhanced compute engine is turned on for dataflow workload. Please check.

     

    Best Regards,

Hello

 

I raised a support call with Microsoft as some of our dataflows on Premium  had started to error with Param1 = Execution Timeout Expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.  (One of the dataflows had this error, even though it was not a computed entity and it ran successfully outside of Premium).
Response from Microsoft:
This known issue is very recent but I've engaged the Engineering team and they are already working on a fix for this issue.  The timeline for the fix should be the end of the next week.  Hence, we believe that by November 18th the issue should be fixed.
At this moment, the available workaround is to disable the enhanced compute engine until the fix is deployed.

I confirm that after the Compute Engine on Premium was turned off and I had allocated more memory to dataflows on the Premium Capacity that the larger sized computed entities ran successfully.  I needed to allocate more memory to dataflows as some of the larger sized computed entities then returned the error that  Evaluation ran out of memory after the Compute Engine was turned off.
