I'm trying to build first dataflow and it is very slow so I cannot wait (40 minutes to show dataflow).
How to check what is going on, where can I find some hint what is wrong ?
Hi @bielakm ,
What connection mode are you using to create this dataflow?
We suggest Using DirectQuery with dataflows - Power BI | Microsoft Learn.
You may reduce the number of records you are using to undertake transformation / cleansing processes.
and also remove what you don't need.If you have records with numerical values sitting in Text-based format, convert them to numerical values.
