Import vs DirectQuery

Advantages of Using DirectQuery

  • Using DirectQuery, you can build data visualizations on large datasets, which is not feasible to import in Power BI desktop.
  • DirectQuery doesn’t apply any 1GB data set limit.
  • With the use of DirectQuery, the report always shows current data.

Limitations of Using DirectQuery

  • There is a limitation of 1 million row for returning data while using DirectQuery. You can perform aggregation of more number of rows, however, the result rows should be less than 1 million to return the dataset.
  • In DirectQuery, all tables should come from a single database.
  • When a complex query is used in the Query editor, it throws an error. To run a query, you need to remove the error from the query.
  • In DirectQuery, you can use Relationship filtering only in one direction.
  • It doesn’t support special treatment for time-related data in tables.
