Your Warehouse, Your Semantic Model

A speaking session by Jonathan Stewart · sqlbites.net

Stop tuning measures. Fix the layer underneath. With Direct Lake, your Power BI model reads the warehouse's own Parquet files in place — one copy of the data, zero refresh to schedule. That means how the warehouse stores rows (MERGE, clustering, V-Order, snapshots) is now directly visible in your report's load time. We build the warehouse so the semantic model is fast by construction, not by firefighting DAX after the fact.
