    Creating extract runs indefinitely

    Andrew Steed

      Hi,

       

      I'm trying to create an extract where the source data contains ~65 million rows. First I tried from a connection to AWS, and the extract creation ran for about 20 hours before I stopped it - and it somehow got into the hundreds of millions of rows! I tried again with flat files as the source, and I got the same result - never ending extract creation reporting way more data than actually exists in the source.

       

      1) Why won't my extract create properly?

       

      2) How does Tableau keep reading in records well past what the database actually contains?

       

      Any help would be greatly appreciated!
