This page details how to install the Starburst (Trino) integration v2.0.
The plugin comes pre-installed with Starburst Enterprise, so this page provides separate sets of guidelines for configuration:
Starburst Cluster Configuration: These instructions are specific to Starburst Enterprise clusters.
Trino Cluster Configuration: These instructions are specific to open-source Trino clusters.
A valid Starburst Enterprise license.
Starburst does not support using Starburst built-in access control (BIAC) concurrently with any other access control providers such as Immuta. If Starburst BIAC is in use, it must be disabled to allow Immuta to enforce policies on cluster.
Click the App Settings icon in the left sidebar.
Click the Integrations tab.
Click Add Native Integration and select Trino from the dropdown menu.
Click Save.
If you are using OAuth or asynchronous authentication to create Starburst (Trino) data sources, configure the globalAdminUsername property in the advanced configuration section of the Immuta app settings page.
Click the App Settings page icon.
Click Advanced Settings and scroll to Advanced Configuration.
Paste the following YAML configuration snippet in the text box, replacing the email address below with your admin username:
Default Configuration Property Values
If you use the default property values in the configuration file described in this section,
you will give users read and write access to tables that are not registered in Immuta and
results for SHOW queries will not be filtered on table metadata.
These default settings help ensure that a new Starburst integration installation is minimally disruptive for existing Starburst deployments, allowing you to then add Immuta data sources and update configuration to enforce more controls as you see fit.
However, the access-control.config-files property can be configured to allow Immuta to work with existing Starburst installations that have already configured an access control provider. For example, if the Starburst integration v2.0 is configured to allow users write access to tables that are not protected by Immuta, you can still lock down write access for specific non-Immuta tables using an additional access control provider.
TLS Certificate Generation
If you provided your own TLS certificates during Immuta installation, you must ensure that the hostname in your certificate matches the hostname specified in the Starburst (Trino) configuration.
If you did not provide your own TLS certificates, Immuta generated these certificates for you during installation. See notes about your specific deployment method below for details.
Kubernetes Deployment: Immuta generates a local certificate authority (CA) that signs certificates for each service by default. Ensure that the externalHostname you specified in the Immuta Helm Chart matches the Immuta hostname name specified in the Starburst (Trino) configuration.
If the hostnames in your certificate don't match the hostname specified in your Starburst (Trino) integration, you can set immuta.disable-hostname-verification to true in the Immuta access control config file to get the integration working in the interim.
The Starburst (Trino) integration uses the immuta.ca-file property to communicate with Immuta. When configuring the plugin in Starburst (outlined below), specify a path to your CA file using the immuta.ca-file property in the Immuta access control configuration file.
Create the Immuta access control configuration file in the Starburst configuration directory (/etc/starburst/immuta-access-control.properties for Docker installations or <starburst_install_directory>/etc/immuta-access-control.properties for standalone installations).
The table below describes the properties that can be set during configuration.
Enable the Immuta access control plugin in Starburst's configuration file (/etc/starburst/config.properties for Docker installations or <starburst_install_directory>/etc/config.properties for standalone installations). For example,
The example configuration snippet below uses the default configuration settings for immuta.allowed.immuta.datasource.operations and immuta.allowed.non.immuta.datasource.operations, which allow read access for data registered as Immuta data sources and read and write access on data that is not registered in Immuta. See the Granting Starburst (Trino) privileges section for details about customizing and enforcing read and write access controls in Starburst.
Configure your external IAM to add users to Immuta.
Map their Starburst usernames when configuring your IAM (or map usernames manually) to Immuta.
All Starburst users must map to Immuta users or match the immuta.user.admin regex configured on the cluster, and their Starburst username must be mapped to Immuta so they can query policy-enforced data.
A user impersonating a different user in Starburst requires the IMPERSONATE_USER permission in Immuta. Both users must be mapped to an Immuta user, or the querying user must match the configured immuta.user.admin regex.
Register Starburst (Trino) data in Immuta.
Click the App Settings icon in the left sidebar.
Click the Integrations tab.
Click Add Native Integration and select Trino from the dropdown menu.
Click Save.
If you are using OAuth or asynchronous authentication to create Starburst (Trino) data sources, configure the globalAdminUsername property in the advanced configuration section of the Immuta app settings page.
Click the App Settings page icon.
Click Advanced Settings and scroll to Advanced Configuration.
Paste the following YAML configuration snippet in the text box, replacing the email address below with your admin username:
A user with access to Immuta's Archives site is required to conduct the download in this step at https://archives.immuta.com. If you are prompted to log in and need basic authentication credentials, contact your Immuta support professional.

The Immuta Trino plugin version is updated alongside Trino so that a matching version of the plugin is published for corresponding Trino releases. For example, the Immuta plugin version supporting Trino version 403 is simply version 403. Download the plugin from version from Immuta's Archives site that corresponds with the Trino version you use.
Enable Immuta on your cluster. Select the tab below that corresponds to your installation method for instructions:
Docker installations
Follow Trino's documentation to install the plugin archive on all nodes in your cluster.
Create the Immuta access control configuration file in the Trino configuration directory: /etc/trino/immuta-access-control.properties.
Standalone installations
Follow Trino's documentation to install the plugin archive on all nodes in your cluster.
Create the Immuta access control configuration file in the Trino configuration directory: <trino_install_directory>/etc/immuta-access-control.properties.
Configure the properties described in the table below.
Enable the Immuta access control plugin in Trino's configuration file (/etc/trino/config.properties for Docker installations or <trino_install_directory>/etc/config.properties for standalone installations). For example,
The example configuration snippet below uses the default configuration settings for immuta.allowed.immuta.datasource.operations and immuta.allowed.non.immuta.datasource.operations, which allow read access for data registered as Immuta data sources and read and write access on data that is not registered in Immuta. See the Granting Starburst (Trino) privileges section for details about customizing and enforcing read and write access controls in Starburst.
Configure your external IAM to add users to Immuta.
Map their Trino usernames when configuring your IAM (or map usernames manually) to Immuta.
All Trino users must map to Immuta users or match the immuta.user.admin regex configured on the cluster, and their Trino username must be mapped to Immuta so they can query policy-enforced data.
A user impersonating a different user in Trino requires the IMPERSONATE_USER permission in Immuta. Both users must be mapped to an Immuta user, or the querying user must match the configured immuta.user.admin regex.
| Property | Starburst version | Required or optional | Description |
|---|---|---|---|
| Property | Trino version | Required or optional | Description |
|---|---|---|---|
access-control.name
392 and newer
Required
This property enables the integration. Both the Starburst integration and the Starburst integration v2.0 can be enabled at the same time. The immuta.allowed.non.immuta.datasource.operations property (explained below) must contain at least READ when both integrations are enabled.
access-control.config-files
392 and newer
Optional
Starburst allows you to enable multiple system access control providers at the same time. To do so, add providers to this property as comma-separated values. Immuta has tested the Immuta system access control provider alongside the Starburst built-in access control system. This approach allows Immuta to work with existing Starburst installations that have already configured an access control provider. Immuta does not manage all permissions in Starburst and will default to allowing access to anything Immuta does not manage so that the Starburst integration v2.0 complements existing controls. For example, if the Starburst integration v2.0 is configured to allow users write access to tables that are not protected by Immuta, you can still lock down write access for specific non-Immuta tables using an additional access control provider.
immuta.allowed.immuta.datasource.operations
413 and newer
Optional
This property defines a comma-separated list of allowed operations for users on Immuta data sources they are subscribed to: READ,WRITE, and OWN. (See the Customize read and write access policies for Starburst (Trino) guide for details about the OWN operation.) When set to WRITE, all users granted access to a data source through a subscription policy are allowed read and write operations to data source schemas and tables. By default, this property is set to READ, which blocks write operations on data source tables and schemas. If write policies are enabled for your Immuta tenant, this property is set to READ,WRITE by default, so users granted write access to a data source through a write access subscription policy are allowed read and write operations to data source schemas and tables.
immuta.allowed.non.immuta.datasource.operations
392 and newer
Optional
This property defines a comma-separated list of allowed operations users will have on tables not registered as Immuta data sources: READ, WRITE, CREATE, and OWN. (See the Customize read and write access policies for Starburst (Trino) guide for details about CREATE and OWN operations.) When set to READ, users are allowed read operations on tables not registered as Immuta data sources. When set to WRITE, users are allowed read and write operations on tables not registered as Immuta data sources. If this property is left empty, users will not get access to any tables outside Immuta. By default, this property is set to READ,WRITE. If write policies are enabled for your Immuta tenant, this property is set to READ,WRITE,OWN,CREATE by default.
immuta.apikey
392 and newer
Required
This should be set to the Immuta API key displayed when enabling the integration on the app settings page.
immuta.ca-file
392 and newer
Optional
This property allows you to specify a path to your CA file.
immuta.cache.views.seconds
392 and newer
Optional
Amount of time in seconds for which a user's specific representation of an Immuta data source will be cached for. Changing this will impact how quickly policy changes are reflected for users actively querying Starburst. By default, cache expires after 30 seconds.
immuta.cache.datasource.seconds
392 and newer
Optional
Amount of time in seconds for which a user's available Immuta data sources will be cached for. Changing this will impact how quickly data sources will be available due to changing projects or subscriptions. By default, cache expires after 30 seconds.
immuta.endpoint
392 and newer
Required
The protocol and fully qualified domain name (FQDN) for the Immuta instance used by Starburst (for example, https://my.immuta.instance.io). This should be set to the endpoint displayed when enabling the integration on the app settings page.
immuta.filter.unallowed.table.metadata
392 and newer
Optional
When set to false, Immuta won't filter unallowed table metadata, which helps ensure Immuta remains noninvasive and performant. If this property is set to true, running show catalogs, for example, will reflect what that user has access to instead of returning all catalogs. By default, this property is set to false.
immuta.group.admin
420 and newer
Required if immuta.user.admin is not set
This property identifies the Starburst group that is the Immuta administrator. The users in this group will not have Immuta policies applied to them. Therefore, data sources should be created by users in this group so that they have access to everything. This property can be used in conjunction with the immuta.user.admin property, and regex filtering can be used (with a | delimiter at the end of each expression) to assign multiple groups as the Immuta administrator. Note that you must escape regex special characters (for example, john\\.doe+svcacct@immuta\\.com).
immuta.user.admin
392 and newer
Required if immuta.group.admin is not set
This property identifies the Starburst user who is an Immuta administrator (for example, immuta.user.admin=immuta_system_account). This user will not have Immuta policies applied to them because this account will run the subqueries. Therefore, data sources should be created by this user so that they have access to everything. This property can be used in conjunction with the immuta.group.admin property, and regex filtering can be used with a | delimiter at the end of each expression) to assign multiple users as the Immuta administrator. Note that you must escape regex special characters (for example, john\\.doe+svcacct@immuta\\.com).
access-control.name
392 and newer
Required
This property enables the integration.
access-control.config-files
392 and newer
Optional
Trino allows you to enable multiple system access control providers at the same time. To do so, add providers to this property as comma-separated values. This approach allows Immuta to work with existing Trino installations that have already configured an access control provider. Immuta does not manage all permissions in Trino and will default to allowing access to anything Immuta does not manage so that the Starburst (Trino) integration complements existing controls. For example, if the Starburst (Trino) integration is configured to allow users write access to tables that are not protected by Immuta, you can still lock down write access for specific non-Immuta tables using an additional access control provider.
immuta.allowed.immuta.datasource.operations
413 and newer
Optional
This property defines a comma-separated list of allowed operations for users on Immuta data sources they are subscribed to: READ,WRITE, and OWN. (See the Customize read and write access policies for Starburst (Trino) guide for details about the OWN operation.) When set to WRITE, all users granted access to a data source through a subscription policy are allowed read and write operations to data source schemas and tables. By default, this property is set to READ, which blocks write operations on data source tables and schemas. If write policies are enabled for your Immuta tenant, this property is set to READ,WRITE by default, so users granted write access to a data source through a write access subscription policy are allowed read and write operations to data source schemas and tables.
immuta.allowed.non.immuta.datasource.operations
392 and newer
Optional
This property defines a comma-separated list of allowed operations users will have on tables not registered as Immuta data sources: READ, WRITE, CREATE, and OWN. (See the Customize read and write access policies for Starburst (Trino) guide for details about CREATE and OWN operations.) When set to READ, users are allowed read operations on tables not registered as Immuta data sources. When set to WRITE, users are allowed read and write operations on tables not registered as Immuta data sources. If this property is left empty, users will not get access to any tables outside Immuta. By default, this property is set to READ,WRITE. If write policies are enabled for your Immuta tenant, this property is set to READ,WRITE,OWN,CREATE by default.
