Have you ever wondered what makes Power BI so fast and powerful when it comes to performance? So powerful, that it performs complex calculations over millions of rows in a blink of an eye.

In this session, we will dig deep to discover what is under the hood of Power BI, how your data is being stored, compressed, queried, and finally, brought back to your report. We will also cover some core concepts that affect Power BI performance, such as Aggregations, Materialization, and Relationships.

After the session, you will get a better understanding of the hard work happening in the background and appreciate the importance of creating an optimal data model in order to get maximum performance from the Power BI engine.

Finally, you will see a real-life demo showing how the Power BI data model was reduced by 90%!
