Hi all. New to Tableau Server. I'm trying to understand the Data Source Connector role. If Tableau Server runs all the data extracts on a schedule, and interactors only work with data extracts kept locally on the server, then what is Connect authority used for? Wouldn't you only need this if you were going against the live data source, and not an extract? Or am I confused in thinking that Tableau Server interactors can only go against data extracts (that's where I'd put my money )?
