What is the main role of the Backgrounder process in Tableau Server?

The Backgrounder process in Tableau Server is primarily responsible for running background tasks related to data processing. This includes executing tasks such as refreshing data extracts, running subscriptions, and performing scheduled tasks that do not require user interaction. By handling these background tasks, the Backgrounder ensures that processes which can take time to complete do so without blocking the primary operations of the server or the user interface. It optimizes the performance and efficiency of Tableau Server by allowing users to engage with the platform without interruption while data is being prepared and updated in the background.
