    Row Security: Data Source or Context Filter?

    Jonathon Stewart

      Hey folks,

       

      I've got a published data source on Tableau Server that includes a username column.  In my reports, I include a "filter by condition" with the following formula: username = USERNAME().  This ensure that users can only access data associated with their username.

       

      Would I see better performance if I add this filter as a data source filter, context filter, or neither?

       

      Cheers,

      Jonathon

       

      P.S. Using latest versions of Tableau 9.3 Server and Desktop.
