I'm new in the BI field and I have to develop the BI of over 25 million records.
I'm using DirectQuery to import the data to PowerBi and to web. But the dashboard loading is too slow. And sometimes the dashboard won't load.
I'd like to know what's the best way to import big amount of data to PowerBI and to publish in the web after the fact.
DirectQuery, Analysis Service, what else?
Thanks for the answers.
