When selecting the "Use all Data" option for a data source in Tableau Prep, the data is showed as sampled in the flow regardless.

In other words, you may notice the following scenarios: 

  • Previewing cleaned steps shows the data as being sampled and limit to 275K rows, regardless if "Use All Data" is selected. 
  • The output will still utilize all the data, but the preview window will show "Sampled" where all data should be available in the preview.
