Regarding live, from the help file on Tableau Prep:
Note: You can publish data extracts or data sources to Tableau Desktop and Tableau Server version 10.0 and later as well as to Tableau Online. Setting up schedules in Tableau Server or Tableau Online to automatically refresh your data outputs is not yet supported.
Please see the following link regarding use of Extracts & Refreshes. I tested with MS-Excel and was able to add a sheet, manually click the refresh icon in Tableau Prep and the sheet appeared and ready to be added to the data pane. Same concept applies for a new row of data within a pre-existing sheet. Click the refresh button in the upper left of the data pane. Then click output to rerun the flow with all of the cleaning and other prep done to overwrite the prior output/data source.
If this answers your question, please mark it as correct. Thx, Don
Thank you Don.
So are we saying
1) Tableau Prep by default extract data once a flow is created?
2) No option to switch between Live or Extract in Prep like we have in Desktop?
I got the idea of manually re-running a prep flow to get latest data but this would mean we can rollout a datasource prepared with Tableau Prep as it cannot be automatically refreshed daily through a schedule.
Also if Tableau Prep flow cannot be live, we cannot leverage some of DB concepts or features.
