Hi @Alwaleed ,
The warning simply means that Spark can't read the SQL dataset directly. So it will need to use DSS to read the data which will be slower because it's not distributed. 

If you want to enable direct spark reads for compatible database you need to enable the option at the connection level :

Then you will need to enable on the dataset level Screenshot 2024-05-02 at 12.39.21 PM.png
