Solved: Direct Lake Restrictions and Limitation - Microsoft Fabric . . . However, Direct Lake's default behavior requires users to have appropriate permissions to the source data, leading to access denied errors The recommended solution would be to creating and using a service principal to mediate access between users and the Lakehouse data
Direct Lake overview - Microsoft Fabric | Microsoft Learn Direct Lake is a storage mode option for tables in a Power BI semantic model that's stored in a Microsoft Fabric workspace It's optimized for large volumes of data that can be quickly loaded into memory from Delta tables stored in OneLake —the single store for all analytics data
Fabric Direct Lake: Memory Utilization with Interactive Operations Some queries will execute faster in import mode and some will execute slower Overall, queries touching memory-resident columns should be comparable Therefore, if Direct Lake is an option for you, it should be at the forefront of your efforts to combat out-of-memory errors with large datasets
Comprehensive Guide to Direct Lake Datasets in Microsoft Fabric Microsoft announced an innovative dataset storage mode for Power BI called Direct Lake at Microsoft Build It fundamentally changes how we create and consume BI solutions It promises to provide the perfect balance between import and Direct Query modes But does it? Let's dig into it and understand the hows and whats of it
Import vs Direct Query vs Direct Lake in Microsoft Fabric Direct Lake mode in Microsoft Fabric lets Power BI read data directly from files stored in OneLake without copying it It gives you fast performance like Import mode using the VertiPaq engine, but with real-time data like Direct Query, it gives you best of both
Solved: Direct Lake Model Resource Limit - Microsoft Fabric Community exceeding the memory limit in Direct Lake doesn’t automatically trigger a fallback to DirectQuery mode Instead, it causes excessive paging in and out of model data from OneLake, which significantly impacts performance and can lead to resource errors
Leveraging pure Direct Lake mode for maximum query performance We are happy to announce a new Direct Lake semantic model property to control Direct Lake behavior Direct Lake, by default, will transparently fallback to DirectQuery whenever a DAX query exceeds the limits on a SKU or uses features not supported by Direct Lake mode, such as SQL views from the Warehouse
Understand Direct Lake query performance - Microsoft Fabric These are common best practices that can help to ensure fast query execution in cold, semiwarm, warm, and hot Direct Lake mode states This article explains how Direct Lake performance depends on Delta table health and efficient data updates Understanding these dependencies is crucial
Direct Lake vs. Import mode in Power BI - SQLBI Direct Lake has modeling limitations compared to Import: You cannot use calculated columns, calculated tables, and MDX user hierarchies in Direct Lake The latter impacts Excel’s user experience when consuming semantic models published on Power BI
How to determine if Direct Lake dataset is falling back to Direct Query . . . In Power BI, when utilizing Direct Lake mode, the semantic models directly read delta tables from OneLake However, it may happen that if there are issues with Direct Lake, the DAX query might switch to DirectQuery There are multiple reasons for this behavior, with the most common ones being:
