Power BI storage modes compared: Direct Lake's silent switch poses risk

By PulseAugur Editorial · [1 sources] ·

A Power BI user conducted a performance comparison of Import, DirectQuery, and Direct Lake storage modes using the same dataset. The tests revealed significant performance differences, with one mode running in under a second and another taking fourteen seconds. A critical finding was that Direct Lake mode silently switched to another mode when a row-level security role was added, posing a potential production risk. AI
