New to Power BI. I imported all my data. It took longer than I had hoped but figured now that the data was imported additional transformations/additions would go fast. I added one column to one of my tables and when I applied the changes it took a half hour to reload that table! The table was not that big - less than 1 million records.
Am I guessing I am doing something wrong? No other tool would take this long. Thanks for any help,
