    Data blending Zip codes performance issue


      I am looking for the best / most efficient way to blend or join a secondary data source which contains a master zip to territory mapping.


      Primary data source: (live connection tableau online) each row has a zip

      Secondary data source: (excel) master zip file with ~40k rows (all US zips) - each zip is tied to a territory


      I am looking to add the territories from the master zip to territory file as a filter.


      I tried data blending using the zip codes as a common field but I am facing very slow performance.


      Is there a better way to do this?
