Power Platform Dataflow Timeout or Error

[mweschenburg]

I am using the new Power Platform Dataflow connector announced in August 2021 release.  I am using the connector in a dataflow to reference another dataflow.  All dataflows are in Premium Gen2 with Enhance Computed on.

I can create a simple dataflow with a small table and it works fine.  I then try to add a second table with 20 million rows.  That times out after 10 minutes during validation (see image).  I can still save the dataflow without validation and then I am able to refresh it successfully.

However, I am unable to do any additional dataflow transformations because the large table is not validated.  If I let the dataflow creator window timeout and then use the advanced editor to add a merge trahsformation, I can save the dataflow (see below digram).  But when I try to refresh the dataflow, it fails with following error.

Error: DataSource.MissingClientLibrary: ADO.NET: Unable to find the requested .Net Framework Data Provider.  It may not be installed. DataSourceKind = PowerPlatformDataflows DataSourcePath = PowerPlatformDataflows. RootActivityId = df7c1fa9-5510-4383-96f4-9c5fd2b9f1d6.Param1 = DataSource.MissingClientLibrary: ADO.NET: Unable to find the requested .Net Framework Data Provider.  It may not be installed. DataSourceKind = PowerPlatformDataflows DataSourcePath = PowerPlatformDataflows Request ID: ccb5aa98-c69e-5e5a-077f-615dddfe0f65.

I suspect all the above behaviors are related but cannot figure out what is wrong or how to fix.

Hello, I'm having a similar problem, did you get a fix from MS?

ADO library not available.

Thanks

Microsoft notified me last week that a fix was released on 30-Sep or 1-Oct.  This fixed the timeouts I was experiencing.  It did not fix the ADO library not available error.  I reported that back to Microsoft yesterday and they are investigating.  You probably can't tack onto my support ticket, but heres my Microsoft ticket number that might help as a reference should you contact Microsofy yourself.

I don't think this is an issue with your process.  The new dataflows are rather half baked currently. If you have a Pro license you should consider raising a Pro ticket at https://powerbi.microsoft.com/en-us/support/pro/
