    How does tableau server data source works?

    Vikram Rathi



         I wanted to know how does tableau server perform updates on data sources. Consider an example where I published a data source (created from athena table) from my tableau desktop to tableau server with live connection mode then how does tableau server keep the data updated from my athena table?

      • Does tableau queries the whole data source each time an update is made or there is some other approach used internally?
      • What is the exact difference in Extract mode of data connection and Live mode of data connection?
