Data Flow Performance degradation
It seems to me that the Performance of the DataFlow Generation on PowerBI Service has degraded considerably in the past weeks
I am Seeing two Errors
1 - the Query will fail often when editing with the data preview on with the error dataflow timed Out
(it is possible to switch to the Schema View and Continue)
2 - when saving and Validating Queries it will take Literally Hours to Validate and save (Stuck at we are Validating... (retrieving table schema X of Y)
Once saved the query Processes in ~25min
These errors above make it Practically IMpossible to Edit Dataflows

I just tried to edit a dataflow and it is still loading after 20 minutes.
Hi,
According to my research, there’s a similar ICM that has been submitted internally. ICM: 239700284
But if you want to get a solution for this kind of problem as soon as possible, I still suggest you to open a support ticket to get direct help from the technical support team of Microsoft.

When saving the Dataflow, it takes a very long time to Validate Queries. Sometimes it aborts with unexpected error. Sometimes it runs for hours and never finishes saving the modification aplied.
