There are a couple of relevant Fabric announcements this week. The first is the Introduction of access limits in a Fabric workspace - that is, you will no longer be allowed to have more than 1000 users+groups directly assigned to a workspace in Power BI/Fabric, which I can't imagine will be an issue for too many of us. The other announcement is the Sunsetting of Default Semantic Models – Microsoft Fabric, which has been a hot request from many in the community ever since Fabric was released. Default semantic models are those which are automatically created when you provision a Lakehouse in Fabric. There's currently no way to switch these off so they're not created in the first place, nor delete them when they're created. So this is welcome news!
Elsewhere this week, a couple of articles on more advanced Semantic Modeling features: Laura Graham-Brown has written about how Calculation Groups aren’t scary and Zoe Douglas has taken us through Perspectives in Power BI semantic models.
