    How to optimise field calculations and workbook performance?

    Narbukra Lakina

      Hello,

       

      I have a workbook with too many calculated fields that are computationally very expensive- All rows need to be scanned to calculate each value of the field.

      On click on every sheet, Tableau spend 5-10 minutes to calculate fields in the view, which makes user experience terrible.

       

      If I use a Tableau Extract, will all calculated fields be calculated during Extract refresh and stored in the Extract?

      In other words, the values of calculated fields will be stored as "ready-to-use" values in the Extract and not calculated during the workbook navigation?

       

      Also, is there another way to optimise calculations performance in Tableau while maintaining live connection to the data?

       

      Thanks
