I'm building report on PowerBI desktop and setup connection as "Live Connection"/"Direct Query". Here is an example Power BI report visual on a DirectQuery model:Get Help with Power BI; Desktop; Direct Query vs Import; Reply. Models developed in DirectQuery mode don’t import data. In recent months, I was frequently asked if one should use tables or views when IMPORTING data in Power BI. Though you can build real-time reports with DirectQuery, push datasets offer a more scalable, economical, and effective solution especially when combined with an Import model already in place. Direct Lake is based on loading parquet-formatted files directly from a data lake without having to query a Lakehouse endpoint, and without having to import or duplicate data into a Power BI dataset. This speeds up import enormously. ). This UI is basically the use of Power Query to import data. Depending on the source, Power Query can send some of the transformations to the source. SQL Profiler is a tool that you can use to capture queries sent to a SQL Server database. To measure embedded performance, you can use two events: Loaded event: The time until the report is initialized (the Power BI logo disappears when the load is finished). Live (2021).
