Update backfill in chunks for incremental refresh

I'm using a large table as a dataset in Power BI. I applied an incremental refresh to this dataset, but after publishing with the initial scope defined by the RangeStart and RangeEnd, it requires a one-time back fill of archived data. I am running into connection and timeout issues with this back fill. Is there a way to run this back fill in smaller chunks? 

  • Use CSV or Parquet files as fake partitions and then append them in Power Query.   Yes, you will reload all the data each time but both CSV and Parquet are ingesting very fast.
