Which TSM process serves as the single source of truth?

The Coordination Service is the component in Tableau Server Management (TSM) that acts as the single source of truth for the Tableau Server architecture. Its primary role is to maintain the state of the server and manage how different processes communicate with one another. This service keeps track of the configuration and health of the server, ensuring that all components operate in harmony.

By serving as a central point of reference for various activities and statuses across the server, the Coordination Service ensures consistency and integrity of operations such as data requests, workload management, and service availability. It allows for more reliable interactions between the Tableau Server processes by maintaining an up-to-date overview of what each component is doing, which is critical for the overall functionality of the server.

The other processes mentioned, such as Database Maintenance, Client File Service, and Backup/Restore, have important roles but do not serve as a comprehensive system reference for the operational status or configuration of the entire Tableau Server. Database Maintenance focuses on the health of the underlying databases, Client File Service manages files associated with client requests, and Backup/Restore is concerned with the processes for data protection and recovery rather than real-time operation management.
