Data Modeling is the most underestimated task when it comes to performance, easy DAX and a easy-to-use semantic model in Fabric and Power BI.
In this table talk we want to publicly discuss usual problems and their solutions we see in our daily work as consultants with a broad range of customers (some import a single Excel-File into Power BI while others created near-real-time reports based on Tera bytes of data).
Feel free to bring your own question so we can make this hour as interactive as possible.
