Slow Dataflow Refresh

Submitted by Advocate IV on ‎10-27-2021 12:28 AM

Hi Everyone

 

Is anyone experiencing slow dataflow refreshes? Since this morning, I have a dataflow that is taking very long to refresh. I haven't edited the dataflow for at least a month and it has been working fine up to now.

 

A simple text-inputed table (4 rows, 2 columns) took 15 minutes to update. Another similar table took 27 minutes to update. Both of these tables are not linked to an external data source and should usually take 30s to refresh. I cancelled the refresh after about 2h30. The dataflow was not even half-way through a refresh that normally takes 20 minutes.

 

I aborted the second attempt at refreshing the dataflow after about an hour and the first table (text-inputed, 3 rows, 2 columns) had not yet refreshed.

Status: Delivered

Based on the discussion in this post, It looks like an issue happened in specific region Europe and it has been fixed up to now. If there is still someone has this issue and it's continuous in the case of  simple table structure and not very large data amount, please consider opening support ticket for further help. 

 

Best Regards,

Same issue here. Even a new dataflow with only 1 empty tabel is giving a time-out.

I have the same issues since yesterday. I have just two Dataflows which take over then 3 hours to load from source. I have a gateway in place that have a sql server as a connection. I also don´t change anything on the dataflow. 

 

Is there any Microsoft Power BI support answer for this issue? Are there any issues with the POwer BI Service?

Same here. Region West Europe. Tonight the dataflows refreshed, but of this morning it is not possible to refresh anymore.

 

Mainly the data comes from storage accounts (parquet files).

I created a dataset with the same parquet file as source. And then tried to refresh the dataset. This is also extremly slow.

Hopefully they fix it significantly faster than last time (june this year) when my customers couldn't refresh for 2 weeks. It's hard to sell this to your customers when the service is so intermittend and support from Microsoft is close to none. Again no mention of any issues anywhere except for this forum thread.

We have the same problem! It's very bad because all report based on dataflows. Please, correct it ASAP.

Same issue using power bi desktop!

 

Community is going faster than Microsoft Support services because going to power BI support webpage (https://powerbi.microsoft.com/en-us/support/), you can read right now: 

 

"No known issues: Power BI is running smoothly"

 

A joke!

Exceptionally frustrating for enterprise software
