    Custom Polygons - very slow when using filters

    Kevin Das

      Hi all

       

      I have created a TDE file with custom polygons in England and Wales. These work well when I map them in Tableau and I am able to show sales per polygon (the sales are from a secondary data source, where sales are aligned to the name of each polygon).

       

      However, when I try to filter the data to show polygons in one region it takes hours and hours to create the view (I cancelled it after 6 hours yesterday!).

       

      I have used other TDE files with polygons where I have created the same types of map and the views have been quick to change with filters.

       

      My TDE is quite large compared to these other files (about 5 times the size).

       

      Does anyone know if I am missing something obvious to reduce the number of calculations needed to filter the map view using the TDE file attached?

       

      Many thanks for any help

       

      Best Wishes

       

      Kev
