Direct Lake RLS - DirectQuery fallback

Hi, the official documentation says that if I connect to a table that has RLS in the SQL Analytics Endpoint, Direct Lake will fall back to DirectQuery: Develop Direct Lake semantic models - Microsoft Fabric | Microsoft Learn

 

Does the same thing apply if I don't define the RLS on the lakehouse/warehouse but directly in Power BI?

I've found the answer: Manage Direct Lake semantic models - Microsoft Fabric | Microsoft Learn

 

[...] If different users must be restricted to access only subsets of data, if viable, enforce RLS at the semantic model layer only. That way, users will benefit from high performance in-memory queries.

 

So the answer is no: DirectLake does not fall back to DirectQuery
