What Power BI DirectQuery does to your SQL Server (and how to fix it)

Power BI DirectQuery can quietly overwhelm your SQL Server. Unlike Import mode, DirectQuery sends live T-SQL for every visual interaction, multiplying queries and placing heavy analytical load on the database. This article explains how to identify the worst offending DirectQuery queries, why the generated SQL is often inefficient, and what you can do from the database side, including indexing, Query Store, and reporting views, to improve performance. It also outlines practical changes on the Power BI side and when DirectQuery is simply the wrong architectural choice.
