Aggregation and Composite Model: Power BI Fast and Furious - Reza Rad 

The composite model enables you to have huge tables as a DirectQuery source, and some other smaller tables as in import mode. When we talk about huge tables, performance is always a challenge. In this session, we will talk in deep about how Aggregations can help speed up the performance. You can see how the terabytes of data can be analyzed and visualized in less than a second. You will learn many tips and tricks and internals about Aggregations in Power BI and usage of that in a Composite model. The session is full of live demos.
