Which process controls the storage of extracts in Tableau Server?

The storage of extracts in Tableau Server is managed by the File Store. This component is responsible for holding all the extract files generated and utilized in Tableau Server, ensuring they are stored securely and efficiently. The File Store allows for the extraction and retrieval of data as needed by users and processes within Tableau Server.

When extracts are created in Tableau Desktop and published to Tableau Server, they are saved in the File Store, which is optimized for performance and data retrieval. This means that when users run dashboards or queries that rely on these extracts, the File Store provides quick access to the necessary data, which enhances the overall performance of Tableau Server.

The other components mentioned, while they have their own specific roles, do not directly control the storage of extracts. The Data Server, for instance, is focused on managing and serving data connections and resources for visualization, rather than the physical storage of extracts. The Metrics Service is concerned with tracking usage and performance metrics across the server. The Gateway acts as the entry point to the Tableau Server for requests made by users but does not manage data storage directly.
