Dataflow Incremental Refresh

Hi, I have a question on dataflow incremental refresh. If I'm pulling the data from SQL Server using a query, does it still run the full SQL query first before implementing incremental refresh policy...

    Hi DataSundowner 

     

    According to my understanding, Power BI will load the data that satisfies the SELECT * FROM sales WHERE saledate >='2023-01-01 statement into Power BI. When using incremental refresh, the service will dynamically partition the data and create incremental refresh partitions and historical partitions. In each subsequent refresh, the rows whose date/time is within the refresh cycle will be refreshed. The rows whose date/time is no longer within the refresh cycle will become part of the historical cycle and will not be refreshed again.
