and I created that sample model for training purpose here. Note that 5 minutes for refresh is not a long refresh time. For example, the Power BI report below takes 5 minutes to refresh. Having a long refresh time can cause a log of challenges, for example, you are doing a refresh to develop some changes, but due to the long refresh time, your development speed also reduces, and many other reasons. The long refresh time can be because the data source is slow, or the set of transformations steps used are heavy and makes the process of data preparation a lengthy process. You have a Power BI file that takes a long time to refresh. To learn more about Power BI, read Power BI book from Rookie to Rock Star. I have previously explained some of the benefits of dataflows, and here is another one in action, let’s see how it can help. Does it take a long time to get your data refreshed in your Power BI model? Should you wait for hours for the refresh to finish because you have complex transformations behind the scene? Does the long refresh time make it hard for you to develop your solution? The good news I have for you in this article is how to use Power BI dataflows to help with reducing the refresh time of your Power BI models.
