Tableau Desktop Foundations Practice Question

While configuring a connection to a PostgreSQL database in Tableau Desktop, you choose the Live option rather than Extract. How will Tableau handle query execution and data storage for visualizations in this workbook?

  • Tableau submits a fresh query to PostgreSQL whenever the view is refreshed and stores no local data file.

  • Tableau copies the data into a compressed .hyper extract and queries that file instead of the database.

  • Tableau automatically creates and schedules background refreshes on Tableau Server to keep the workbook updated.

  • Tableau runs a single query once, caches the result permanently, and never reconnects to PostgreSQL.
