Tableau Server Processes

This topic describes the options for setting the process configuration. To configure Tableau Server processes, you need to specify which processes and how many instances should run on each node. You do this using the tsm topology set-process command. For more information, see Changing the number of processes on a node.

Looking for Tableau Server on Linux? See Process Reference(Link opens in a new window).

Except where explicitly noted in the table below, applying changes in processes will stop Tableau Server if it is running when you apply those changes. After changes are applied, Tableau Server is returned to the state it was in before process configuration, so if the server was running, it will be restarted.

Important: Your process topology will depend on your organizational needs.

Licensed processes

Some of the processes that are installed as a part of Tableau Server are "licensed" processes. Licensed processes need a valid Tableau Server license in order to run. Other processes that are installed as a part of Tableau Server are not tied to a valid license. This has the following impact:

Every licensed process needs to regularly contact the Tableau Server License Manager service that runs on the initial Tableau Server computer to verify they are licensed. If they cannot confirm there is a valid license, for example, if the initial node is not available, the process will not run and Tableau Server may not function properly or reliably.
If you have a core-based Tableau Server license, the cores on any node with a licensed process will count against the total count of licensed cores.

Note: If you have Data Management and a core-based license, you will need to understand how the licensed processes will count against the total count of licensed cores that come with each license. For more information, see License Data Management.

The "Licensed" column in the table below identifies those processes that require a valid license, and which impact the count of cores in core-based licenses.

Tableau Server Processes These processes have a status of `running` when Tableau Server is running, and `stopped` when Tableau Server is stopped.
Name shown in `tsm status -v`	Name used with `tsm topology set-process`	Purpose	Notes	Licensed
Analytics Extensions Microservice	`analyticsextensions`	The Analytics Extensions Microservice supports a set of functions to pass expressions to analytics extensions for integration with R, Python, and Einstein Discovery.	Automatically installed on any node where Application Server (VizPortal) is installed.	No
Application Server	`vizportal`	The Application Server (VizPortal) handles the web application, REST API calls, and supports browsing and searching.	When Application Server is installed, Data Engine is also installed, unless the node already has an instance of Data Engine. When the first instance of Application Server is installed on a node, the Interactive Container Service is also installed.	Yes
Ask Data	Cannot be configured manually.	The Ask Data service is used by the Ask Data feature.	Runs automatically on all nodes where Data Server is running.	No
Authentication Added: 2022.1	Cannot be configured manually.	The Authentication service handles the identity migration process and identity pools. After the identity migration process is complete and as part of identity pools management, the Authentication service is responsible for the following: Searching for a user identity in the appropriate Identity Service table, using the returned universal unique identifier (UUID) to query the legacy system_user table and find the appropriate system user, and then granting them a user session, which completes the authentication workflow. Importing immutable user identifiers and additional user attributes when the configured identity store is external (AD or LDAP).	Status for this process is only available through tsm CLI. Identity migration must be complete and the Identity Service turned on to set up and user identity pools. For more information, see About the Identity Migration and Provision and Authenticate Users Using Identity Pools.	No
Backgrounder	`backgrounder`	The Backgrounder runs server tasks, including extract refreshes, subscriptions, ‘Run Now’ tasks, and tasks initiated from tabcmd.	When Backgrounder is installed, Data Engine is also installed, unless the node already has an instance of Data Engine. Backgrounder is a single-threaded process. You can add more instances of backgrounder to a node to expand the capacity of the node to run jobs in parallel. In most situations you can increase or decrease the number of backgrounder instances on an existing node of a running server without causing a stop and restart the server. The exception is when you have Data Management licensed and you add the first instance of backgrounder to a node or remove the last instance of backgrounder from the node. For more information, see Tableau Server Dynamic Topology Changes.	Yes
Cache Server	`cacheserver`	The Cache Server is a query cache distributed and shared across the server cluster. This in-memory cache speeds user experience across many scenarios. VizQL server, backgrounder, and data server (and application server to a lesser extent) make cache requests to the cache server on behalf of users or jobs.	The cache is single-threaded, so if you need better performance you should run additional instances of cache server. We recommend you install no more than a maximum of six cache server instances, limiting each node to no more than two. Our testing indicates that installing more than a total of six cache server instances in a Tableau Server installation provides no improvement, and could have a negative impact on performance.	No
Cluster Controller	`clustercontroller`	The Cluster Controller is responsible for monitoring various components, detecting failures, and running failover when needed.	Automatically installed on every node.	No
Collections Added: 2021.2.0	`collections`	The Collections service provides meta data for the collections and favorites features.	The Collections service is installed on the first node where the Application (vizportal) is installed. For high availability, we recommend you install an instance of the Collections service on every node that has an instance of the Application Server installed. For more information, see Tableau Server Collections Service.	No
Connection Pooling Added: 2023.1.0		The Connection Pooling service is intended to offer an option for pooling database connections to the repository.	The Connection Pooling service is installed on the every node in a disabled state. It cannot be enabled except in TSM. It should not be enabled except by instructions from Tableau Support.	No
Content Exploration Added: 2021.1.0	`contentexploration`	The Content Exploration service extends search and browse capabilities for Tableau Server. It also depends on Index and Search Server to do its operations.	The Content Exploration service is installed on the initial node. For high availability, we recommend you install an instance of the Content Exploration service on every node that has Application Server installed. For more information, see Tableau Server Content Exploration Service.	No
Data Engine	Cannot be configured manually.	The Data Engine creates data extracts and processes queries.	Automatically installed when you install File Store, VizQL Server, Application Server (VizPortal), Data Server, Prep Flow Authoring, or Backgrounder. Note: When File Store is configured externally, Data Engine is no longer installed with File Store. For more information see Tableau Server External File Store.	Yes
Data Profiling Added: 2021.4.0	`dataprofiling`	The Data Profiling service handles column profiling requests for the Virtual Connection editor.	Only installed when you have a Data Management license. Then, automatically installed on any node where Backgrounder is installed.	Yes - Requires a Data Management license
Data Server	`dataserver`	The Data Server manages connections to Tableau Server data sources.	When Data Server is installed, Data Engine is also installed, unless the node already has an instance of Data Engine.	Yes
Data Source Properties Added: 2020.1.0	`tdsservice`	The Data Source Properties service provides published data source metadata to client services like Ask Data.	Data Source Properties is added by default on the initial node. A Tableau Server installation must include at least one instance. For performance reasons, we recommend installing the Data Source Properties service on any node that has Application Server (VizPortal) installed.	No
Data Stories Added: 2023.1.0		The Data Stories service handles the analytical engine that powers the Data Stories dashboard extension.	Data Stories is automatically added to every node of the Tableau Server installation. It cannot be configured manually.	No
Elastic Server Added: 2019.1 Removed: 2022.1 Starting in version 2022.1 Index and Search Server is used instead.	`elasticserver`	Elastic Server is used by Ask Data to index data and by Content Exploration service to index searchable content.	Elastic Server processes can be running on more than one node in a cluster. Optionally, they can be moved to any node. It is recommended to have an odd number of Elastic Server processes running. The Elastic Server heap size can be configured by using the `elasticserver.vmopts` TSM configuration option. For more information, see tsm configuration set Options.	No
Extract Service Added: 2021.4.0	`extractservice`	The Extract service manages extracts of Virtual Connections.	Only installed when you have a Data Management license. Then, automatically installed on any node where Backgrounder is installed.	Yes - Requires a Data Management license

When configured locally: The File Store automatically replicates extracts across Data Engine nodes.	When File Store is installed, Data Engine is also installed, unless the node already has an instance of Data Engine or if File Store is configured externally.	Local File Store: No External File Store: Requires Advanced Management license.
Gateway	`gateway`	The Gateway is a web server that handles all requests to Tableau Server from browsers, Tableau Desktop, and other clients.	Required on any node with an instance of VizQL Server, Vizportal, or Tableau Prep Flow Authoring.	No
Index and Search Server Added: 2022.1	`indexandsearchserver`	Index and Search Server is based on AWS OpenSearch. Tableau uses the search capability of Open Search to index data for Ask Data and the Content Exploration service. This server process is the replacement for Elastic Server which is no longer used in version 2022.1 and later. As of version 2023.3.0, this process replaces Search and Browse.	Index and Search Server can be configured on more than one node in a cluster. We recommended an odd number of Index and Search Server processes running in total. On Tableau Server Clusters that have 3 or more nodes, we recommend that you configure Index and Search Server on at least three different nodes. The Index and Search Server heap size can be configured by using the `tsm set configuration` command with the `indexandsearchserver.vmopts` option. For more information, see tsm configuration set Options.	No
Internal Data Source Properties Added : 2020.1.0	`tdsnativeservice` Cannot be configured manually.	The Internal Data Source Properties service is an internal service that only communicates with the Data Source Properties service.

Tableau Microservice Container Processes These processes are automatically added when the first instance of Backgrounder or Application Server is added to a node. If all instances of Backgrounder or Application Server are removed from a node, the microservice container process is also removed. Container status depends on the status of the microservices within the container. If all microservices are running, the container process has a status of `running`. If all microservices are stopped, the container process status is `error`. If one or more microservices is running while others are not, the container service has a status of `degraded`. For more information, see Tableau Server Microservice Containers.

Process workflow

The Tableau Server processes and how they interact depend on what action or activity is taking place. For example, the processes that are used, and how they interact, differ when you publish a workbook from those used when you sign in using SAML. For some interactive views on process workflow, see the below workbook. This allows you to select a particular workflow and follow it step by step from start to finish.

Disclaimer: This workbook is published on Tableau Public and is not maintained by Tableau documentation. We cannot guarantee that it is up-to-date with the latest version of Tableau Server.
