I agree with James about extracts. But there’s another approach: implement a star schema with pre-aggregated fact tables at different grain levels. Create monthly_sales, weekly_sales, and daily_sales tables. Tableau can query the appropriate grain based on user filter selections. This is how enterprise data warehouses handle exactly this problem.
