Hello.
I have a meeting with a very big customer who already use QlikView and Tableau. Anyway they want to know more about Power BI and see what can Microsoft put on the table. My biggest concern about possible Power BI project there is the amount of data. 1GB pbi file size limit will be exceeded for sure. Transfering databases to Azure is not a matter of discussion. Probably I can use live queries to SSAS but I'm worried about how fast will be.
So, share your experience please. What is the best way to use Power BI for analysis over big databases?
