Check out the various techniques for optimising live connections in Tableau. We will tackle techniques to optimise query performance from the Tableau side as well as the database side. Expect a recap of general performance tips in Tableau, an understanding of what happens under the covers (i.e. order of execution in Tableau, performance recording and implementation plan in a database), and a review of joins vs. blends vs. cross-database joins, performance implications, resulting queries, and more.
