Microsoft yesterday announced that they are increasing the support for data file size on Power BI Premium, a x10 increase compared to before. Users can now upload Power BI Desktop (.PBIX) files that are up to 10 GB in size.
Power BI datasets are highly compressed, representing data volumes many times their size. Power BI Premium in conjunction with large datasets translates to self-service, real-time exploration against data with potentially hundreds of millions of rows.
The following table describes recommended SKUs for various .pbix sizes:
|SKU||Size of .pbix|
|P1||< 3 GB|
|P2||< 6 GB|
|P3||up to 10 GB|
