    Need advice on best way to structure data connections with a large text file and several supplemental joins

      I'm new at Tableau and am beginning to build my first viz from a master population file of 18M records (4GB+) with several much smaller files that add dimensional data.  All sources are .csv files.

       

      Because of the file size, I am doing a full import of the master population file which then causes me to be using the extract.  However, when I then define a join to one of the supplemental tables, I get a message that an extract is active and I can't see the dimensions of the joined table in the data pane unless I switch off extract mode.  What am I doing wrong?
