'Easy Empty Extracts' Sounds like a kids' tongue-twister. But it's actually a hot Tableau tip, courtesy of our very own Ryan Stryker, Sr. Business Consultant, Tableau Professional Services. Thanks, Ryan! Extracts are not a hard sell; the performance gains we see through the local materialization of data views are usually staggering. And Tableau Server gives us a handy platform for automagically refreshing it all. For large extracts, though, it can be quite time-consuming to create a desktop version before publishing to the server. Understandably, customers often ask if there’s a way to “just have Server do it.” Of course there is.
