Node Roles in Tableau Server
Tableau Server on Windows now includes Tableau Services Manager (TSM), which replaces the Configuration Utility and the tabadmin command line tool. If you need help for an earlier version of Tableau Server, see the Tableau Help page.
The Backgrounder process runs server tasks, including extract refreshes, subscriptions, flow tasks, ‘Run Now’ tasks, and tasks initiated from tabcmd. Starting in 2019.1, you can configure the type of tasks that a backgrounder can perform on a node. This applies to Tableau Server installations that have more than one node where backgrounder is enabled.
The following node roles are useful if you have a Tableau Prep Conductor license for your Tableau Server Deployment. For more information, see Tableau Prep Conductor.
By default, Backgrounder is set to perform server tasks of all types. You can customize it to only run flow tasks, or run all tasks other than flows: For more information, see tsm topology.
