How do Power BI developers handle large datasets?-Forum-Culture Informatique

To manage large datasets, Power BI developers use techniques like data partitioning, incremental data refreshes, and aggregating data in summary tables to improve performance. They utilize DirectQuery mode to query live data sources without importing large datasets into Power BI, keeping report size manageable. Power BI developer also optimize the data model by removing unused columns and rows, ensuring efficient data storage. Using composite models, developers can combine imported and live data sources, allowing for better performance with large, complex datasets while maintaining flexibility in analysis.
