Hi Maddy,

 

Please refer to desktop-use-directquery#important-considerations-when-using-directquery and desktop-directquery-about#when-is-directquery-useful.

Regarding the performance, because most of the data is fetched when the report is consumed, the workload of the database is heavier than the import mode.
