Is there any issue with dataflow
I create a dataset from dataflow.
But this morning, I try to add 1 column in datafow and now it takes 30' to refresh data.
I use import mode.
This may or may not explain what you're seeing, but be aware that dataflow performance has been all over the place for weeks now, it's a known issue and Microsoft support has announced it should be fixed by July 21st:

Adding one column can increase refresh time by this much if the granularity level of that column is very high.
You can use vertipaq analyzer to analyze the granularity level of your columns 🙂
