Helper IVIncremental data load in Power BI file
Hi Marico ,
Yes, you can improve report performance even with datasets larger than 5 GB. Power BI offers several methods to help optimize speed and user experience. Here are some tips:
- Use Aggregations: Create summary tables to reduce data volume and improve load times. Power BI can switch between aggregated and detailed data as needed.
- Optimize the Data Model: Remove unused columns and tables, avoid high-cardinality columns, and use numeric keys for relationships.
- Use Hybrid or Composite Models: Store large fact tables in DirectQuery mode and import only smaller dimension tables to save memory.
- Apply Incremental Refresh: Use incremental refresh for large datasets with date/time fields to process only recent or changed data.
- Limit Visual and Filter Interactions: Reduce the number of slicers and filters, and use the "Apply" button for filters to control when visuals update.
- Split Reports: Divide complex reports into multiple pages or files so users only load what they need.
- Use Performance Analyzer: Identify slow visuals or queries with the Performance Analyzer and optimize them.
- Upgrade to Power BI Premium: Premium capacity provides more memory and processing power for large datasets.
Thank you again.
Hi again Marico ,
After reviewing Microsoft’s official documentation on Incremental Refresh in Power BI and the community post at Community Post on Incremental Refresh, I can confirm that Incremental Refresh can absolutely be implemented using a .pbix file. There are a few key steps to follow:
Set up the RangeStart and RangeEnd parameters in Power Query.
Apply filters with these parameters to a date column in your fact table.
Once published to Power BI Service, configure the Incremental Refresh policy in the dataset settings. The initial refresh will process all historical data, but subsequent refreshes will only update the latest partition as specified (such as the last 7 days).
I have shared the incremental document link, the Microsoft link, and also included screenshots. Please review them.
