    Performance issues when using a published vs embedded data source (live connection)

    Alec Redman



      We have a workbook that connects to a Teradata database with a live connection. The workbook is currently published to Tableau Server with the data source embedded. We tried publishing the data source separately to Tableau Server and connecting to it from the workbook, but when doing so the views take significantly longer to load. When using the embedded data source it takes about a minute to load vs. 12-13 minutes when using the published data source. The query is exactly the same in both cases so I'm not sure what's causing the lag when using the published data source.


      Are there any known performance issues when using a published data source over an embedded one for live connections? For reference, we are on version 9.3.1 for both Server and Desktop.
