It often results in slower performance because every interaction sends a query to the underlying data source. Advanced calculations using DAX are restricted in DirectQuery mode, reducing flexibility in report development. Combining multiple data sources in DirectQuery further complicates the process, leading to performance bottlenecks. Power BI developers must invest time in optimizing data sources and queries, which increases project complexity and delays delivery. For businesses demanding quick and complex insights, DirectQuery can be a limiting factor.[/size]
