    Do Data Source Filters Speed Up Extracts?

    Steven Watson

      Hi all,

      I'm dealing with a relatively large data set (several million records). I have filters on the data source that limit to only a few thousand records that come into the visual. However, when I refresh the extract, it takes quite a long time and it appears to be parsing the entire data set before filtering. This is frustrating to have to wait for a long time just to update a few thousand records. I'm using Tableau 10.0.


      Is the above actually happening, or am I misunderstanding? And is there a way to speed this up? Thanks for the help.
