    combine extract and live Data from same Datasource

    jens.bruckmann

      Hi,

       

      I am think about how to reduce the load time of my reports and just had the idea but don´t know if it is possible.

       

      Can I combine an extract and live Data?

       

      As an example I have a simple table whith Date, and maybe a status.

       

      As long as the status is not changed to "done" for example I want to get the live Data, but when the status changed to Done it can be written to the extract as live Data is not necessary anymore.

       

      Can this realised?

          Hi Jens,

          Tableau won't be able to do something like this - extracts (for general purposes) can be thought of as snapshots to fulfill the data connection rather than as a portion of a data connection;  a data connection either works against a live connection or it leverages the extract version (as determined by the author, not the viewer). 

           

          You may create versions of the view/workbook that work against each connection type and direct your users to the correct versions;  I've seen this to be successful for deployments who define a version of the workbook to be the historical, but slower, version vs the workbook that is recent and optimized by extracts.
