[Issue] Dataflow preview timeout – previous workaround no longer working since March 2025
Hi hama21 Could you try splitting the query into smaller parts, parameterizing it to limit rows , or using multiple dataflows to handle portions of the data and consolidating them later? This approach may help manage complexity and bypass the limit
Hi hama21 Try splitting the query into smaller parts, parameterizing it (limiting rows with TOP N during development), or using DirectQuery for staging and switching to Import mode later.This would help in managing query complexity and reducing evaluation time.
If the issue still persists, raise a support ticket with Microsoft
I can't use direct query in dataflow because I can't save without bypass the 10minutes..
