Improving Data Load Speeds with Incremental Refresh

Incremental refresh is a feature originally released for Power BI Premium capacities but has become a feature for Pro licenses as well. Prior to incremental refresh, Power BI only had a single mode of operation when refreshing datasets, full load. In other words, the existing data in the dataset was removed and entirely replaced each time the dataset refreshed. The full load refresh process could take a long time when dealing with large fact tables with millions of rows.
