New in version 2021.4
New features and enhancements related to web authoring and interacting with views on the web are listed in What's New Tableau Desktop and Web Authoring(Link opens in a new window). For topics related to web authoring and interacting with views, see Using Tableau on the Web(Link opens in a new window).
Server or site administrator
Beginning with Tableau Server version 2021.4, server authorisation-to-run (ATR) is now the default way to activate Tableau Server in any on-premises, cloud, container or virtual environment. When impacted by underlying hardware changes (non-container environments), Server ATR reduces the occurrence of maximum activation errors. For more information, see Activate Tableau Server using the authorisation-to-run (ATR) service(Link opens in a new window).
Beginning with Tableau Server on Linux version 2021.4, we now support RHEL 8.3+ (8.1 and 8.2 are not supported).
Note: Tableau Server in a Container does not support RHEL 8 base images.
For details about supported distributions, see Operating system requirements.
Beginning with Tableau Server version 2021.4 the
tsm maintenance ziplogs command now includes
H:mm time options to specify start and end time when using the
--enddate options. This provides additional control for administrators who want to collect logs from a specific date and time segment. These options can result in faster creation of smaller ziplog archives.
For details, see tsm maintenance ziplogs.
Tableau Server version 2021.4 includes the following new services, used with Virtual Connections:
- Data Profiling service
- Extract service
- Minerva service
- Published Connections service
- Query Gateway microservice
- Query Policy service
Beginning in version 2021.4, you can register an external authorisation server (EAS) to establish a trust relationship between Tableau Server and your external authorisation server (EAS). By establishing a trust relationship, you’re able to provide your users with a single sign-on (SSO) experience to Tableau content embedded in your custom applications through your identity provider (IdP). For more information, see Register EAS to Enable SSO for Embedded Content.
This feature includes the following new tsm commands:
Updated Performance Chart for Slow View Load Requests
The Slow View Load Requests chart shows when views are rendering more slowly than normal on Tableau Server, making it easy to quickly identify performance issues related to rendering views. For more information, see Investigating Slow View Load Requests.
New command to update service setup -
Starting in version 2021.4, a new command has been added to allow you to update the setup information for the Resource Monitoring Tool services including RMT Server, Agent, Rabbit MQ and PostgreSQL database. For more information, see rmtadmin-service-setup.
Slow View incident updates
Starting in version 2021.4, you can specify thresholds to include all views or only certain views. Previously, you could only specify duration and users, but now you can select which views you want the thresholds to apply to. For more information, see Slow Views Incidents.
Google Cloud Platform support
Starting in version 2021.4, you can use Google Cloud to set up Tableau Server External Repository. For more information, see Create a PostgreSQL Instance on Google Cloud.
Enable or disable encryption between Tableau Server and External Repository
Starting in version 2021.4, tsm security repository-ssl enable command has been updated to include a new option so you can enable encrypted communication between Tableau Server and the External Repository. For more information, see tsm security repository-ssl enable.
Starting in version 2021.4, you can use the tsm security repository-ssl disable command to stop encrypting traffic between Tableau Server and External Repository. For more information, see tsm security repository-ssl disable.
This change now allows you to update connection security for External Repository for an existing installation.
Tableau Content Migration Tool – part of the Server Management Add-on
Import user mappings from a CSV file
Starting in version 2021.4, you can import a CSV file with domain, user and group mappings to quickly prepare your data for migration. Importing from a CSV file can reduce the manual steps required by allowing you to create and edit your mappings in bulk outside the Content Migration Tool. For more information, see Migration Plans: User Permissions Mapping.
Support for Amazon Athena, Amazon EMR and Salesforce data connection types
Content Migration Tool now supports Amazon Athena, Amazon EMR and Salesforce data connection types. These connections can be modified during migration when applying Data Source Transformations for workbooks and published data sources. For a list of supported data connection types, see Getting Started with Tableau Content Migration Tool.
Virtual connections and data policies – part of the Data Management Add-on
Virtual connections and data policies are included in the separately licensed Data Management Add-on for Tableau Server and Tableau Online. These new data management features enable you to provide a single, centralised connection to a database for your users, as well as define row-level security on the tables in the connection using a data policy. For more information, see About Virtual Connections and Data Policies.
With virtual connections, you get Quick Help
As you create and test your new virtual connection, help is just a click away. Delivered in the product, Quick Help shows relevant, just-in-time help content based on where you are or what you're doing in the virtual connection editor. Simply click on the ‘?’ icon on the top right of your screen to open the movable help window.
Tableau Catalogue – part of the Data Management Add-on
Custom SQL information on content lineage pages – Catalogue lineage pages show information that helps users understand more about custom SQL in their content.
- A banner on lineage pages identifies content that uses custom SQL.
- You can review the custom SQL query.
- A warning is shown for custom SQL queries that could result in incomplete lineage.
For more information, see Supported lineage(Link opens in a new window) in the Tableau Desktop and Web Authoring Help.
Tableau Catalogue supports the T-SQL dialect in custom SQL queries – Support for the T-SQL dialect means Tableau Catalogue can provide more complete lineage when custom SQL is used. For more information, see Supported queries(Link opens in a new window) in the Tableau Desktop and Web Authoring Help.
Data quality warnings links in email automatically open the Data Details pane – When you click on a data quality warning in a subscription email, the view opens with the Data Details pane shown. Also, a new embed parameter, showDataDetails, is available to open the view with the Data Details pane shown. For more information, see Parameters for Embed Code(Link opens in a new window) in the Tableau Desktop and Web Authoring Help.
Inherited descriptions appear in the fields list on lineage pages – When a description for a field exists upstream from the field, it now appears in the fields list on lineage pages with information about where the description is inherited from. For more information, see How field descriptions are inherited(Link opens in a new window) in the Tableau Desktop and Web Authoring Help.
Easily create Prep flows based on external assets – Now you can use databases and tables as starting points for new flows in Prep web authoring. For more information, see Start a new flow(Link opens in a new window) in the Tableau Prep Help.
Beginning with Tableau Server 2021.4, the minimum amount of memory for a production installation of Tableau Server increases from 32 GB to 64 GB. This increase helps ensure a satisfactory experience with Tableau Server and accounts for increased memory needs of newer features.
For customers wanting to do proof of concept testing, we recommend using a Tableau Online account, which will guarantee you a system running on adequate hardware. Tableau Online is also a good option for organisations that would otherwise be running Tableau Server on a single node (a one-computer installation).
For more information about Tableau Server system requirements, see Before you install....
Beginning with Tableau Server 2021.4, search attributes, operators and special characters cannot be used to limit search on Tableau Server and Tableau Online. You can limit the search results using filters. To learn more about searching on Tableau, see Search Your Tableau Site.
In addition to supporting service provider (SP)-initiated single log out (SLO) for both server-wide SAML and site-specific SAML, Tableau Server supports identity provider (IdP)-initiated SLO beginning with Tableau Server 2021.4. For more information about SAML configuration and requirements, see SAML Requirements(Link opens in a new window).
Beginning with Tableau Server version 2021.4, offline activation has been made simpler, with fewer steps required to activate Tableau Server. In addition, the offline activation request file (offline.tlq) has been renamed TableauOfflineActivationRequest.tlq. The offline deactivation request file (deactivate.tlq) has been renamed TableauOfflineDeactivationRequest.tlq. For more information about offline activation, see Offline Activation When Installing Tableau Server(Link opens in a new window). For more information about offline deactivation, see Deactivate Tableau Server Offline(Link opens in a new window).
