Starburst (Trino) version 438 or newer
Write policies for Starburst (Trino) enabled. Contact your Immuta representative to get this feature enabled on your account.
In its default setting, the Starburst (Trino) integration's write access value controls the authorization of SQL operations that perform data modification (such as INSERT, UPDATE, DELETE, MERGE, and TRUNCATE). However, administrators can allow table modification operations (such as ALTER and DROP tables) to be authorized as write operations. Two locations allow administrators to specify how read and write access policies are applied to data in Starburst (Trino). Select one or both of the options below to customize these settings. If the access-control.properties file is used, it may override the policies configured in the Immuta web service.
Immuta web service: Configure write policies in the Immuta web service to allow all Starburst (Trino) clusters targeting that Immuta tenant to receive the same write policy configuration for data sources. This configuration will only affect tables or views registered as Immuta data sources.
Starburst (Trino) cluster: Configure write policies using the access-control.properties file in Starburst or Trino to broadly customize access for Immuta users on a specific cluster. This configuration file takes precedence over write policies passed from the Immuta web service. Use this option if all Immuta users should have the same level of access to tables regardless of the write policy setting in the Immuta web service.
Contact your Immuta representative to configure read and write access in the Immuta web service if all Starburst (Trino) data source operations should be affected identically across Starburst (Trino) clusters connected to your Immuta tenant. A configuration example is provided below.
The following example maps WRITE to READ, WRITE and OWN permissions and READ to just READ. Both READ and WRITE permissions should always include READ:
Given the above configuration, when a user gets write access to a Starburst (Trino) data source, they will have both data and table modification permissions on that data source. See the Starburst (Trino) privileges section of the Subscription policy access types guide for details about these operations.
Configure the integration to allow read and write policies to apply to any data source (registered or unregistered in Immuta) on a Starburst cluster.
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).
Modify one or both properties below to customize the behavior of read or write access policies for all users:
immuta.allowed.immuta.datasource.operations: This property governs objects (catalogs, schemas, tables, etc.) that are registered as data sources in Immuta. For these permissions to apply, the user must be subscribed to the data source in Immuta and not be an administrator (who gets all permissions).
READ: Grants SELECT on tables or views; grants SHOW on tables, views, or columns
WRITE: Grants INSERT, UPDATE, DELETE, MERGE, or TRUNCATE on tables; grants REFRESH on materialized views.
OWN: Grants ALTER and DROP on tables; grants SET on comments and properties
immuta.allowed.non.immuta.datasource.operations: This property governs objects (catalogs, schemas, tables, etc.) that are not registered as data sources in Immuta. Use all or a combination of the following access values:
READ: Grants SELECT on tables or views; grants SHOW on tables, views, or columns
WRITE: Grants INSERT, UPDATE, DELETE, MERGE, or TRUNCATE on tables; grants REFRESH on materialized views.
OWN: Grants ALTER and DROP on tables; grants SET on comments and properties
CREATE: Grants CREATE on catalogs, schema, tables, and views. This is the only property that can allow CREATE permissions, since CREATE is enforced on new objects that do not exist in Starburst or Immuta yet (such as a new table being created with CREATE TABLE).
For example, the following configuration allows READ, WRITE, and OWN operations to be authorized on data sources registered in Immuta and all operations are permitted on data that is not registered in Immuta:
Enable the Immuta access control plugin in the Starburst cluster's configuration file (/etc/starburst/config.properties for Docker installations or <starburst_install_directory>/etc/config.properties for standalone installations). For example,
Create the Immuta access control configuration file in the Trino configuration directory (/etc/trino/config.properties for Docker installations or <trino_install_directory>/etc/config.properties for standalone installations).
Modify one or both properties below to customize the behavior of read or write access policies for all users:
immuta.allowed.immuta.datasource.operations: This property governs objects (catalogs, schemas, tables, etc.) that are registered as data sources in Immuta. For these permissions to apply, the user must be subscribed to the data source in Immuta and not be an administrator (who gets all permissions).
READ: Grants SELECT on tables or views; grants SHOW on tables, views, or columns
WRITE: Grants INSERT, UPDATE, DELETE, MERGE, or TRUNCATE on tables; grants REFRESH on materialized views.
OWN: Grants ALTER and DROP on tables; grants SET on comments and properties
immuta.allowed.non.immuta.datasource.operations: This property governs objects (catalogs, schemas, tables, etc.) that are not registered as data sources in Immuta. Use all or a combination of the following access values:
READ: Grants SELECT on tables or views; grants SHOW on tables, views, or columns
WRITE: Grants INSERT, UPDATE, DELETE, MERGE, or TRUNCATE on tables; grants REFRESH on materialized views.
OWN: Grants ALTER and DROP on tables; grants SET on comments and properties
CREATE: Grants CREATE on catalogs, schema, tables, and views. This is the only property that can allow CREATE permissions, since CREATE is enforced on new objects that do not exist in Starburst or Immuta yet (such as a new table being created with CREATE TABLE).
For example, the following configuration allows READ, WRITE, and OWN operations to be authorized on data sources registered in Immuta and all operations are permitted on data that is not registered in Immuta:
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 Starburst (Trino) integration allows you to access policy-enforced data directly in your Starburst catalogs without rewriting queries or changing workflows. Instead of generating policy-enforced views and adding them to an Immuta catalog that users have to query (like in the legacy Starburst (Trino) integration), Immuta policies are translated into Starburst (Trino) rules and permissions and applied directly to tables within users’ existing catalogs.
Once an Immuta Application Admin configures the Starburst (Trino) integration, the ImmutaSystemAccessControl plugin is installed on the coordinator. This plugin provides policy decisions to the Trino Execution Engine whenever an Immuta user queries a Starburst (Trino) table registered in Immuta. Then, the Trino Execution Engine applies policies to the backing catalogs and retrieves the data with appropriate policy enforcement.
By default, this integration is designed to be minimally invasive: if a catalog is not registered as an Immuta data source, users will still have access to it in Starburst (Trino). However, this limited enforcement can be changed in the configuration file provided by Immuta. Additionally, you can continue to use Trino's file-based access control provider or Starburst (Trino) built-in access control system on catalogs that are not protected or controlled by Immuta.
When you configure the integration, Immuta generates an API key for you to add to your Immuta access control properties file for API authentication between Starburst (Trino) and Immuta. You can rotate this shared secret to mitigate potential security risks and comply with your organizational policies.
To rotate this API key, see the Starburst (Trino) integration API guide.
When a user queries a table in Starburst, the Trino Execution Engine reaches out to the Immuta plugin to determine what the user is allowed to see:
masking policies: For each column, Starburst (Trino) requests a view expression from the Immuta plugin. If there is a masking policy on the column, the Immuta plugin returns the corresponding view expression for that column. Otherwise, nothing is returned.
row-level policies: For each table, Starburst (Trino) requests the rows a user can see in a table from Immuta. If there is a WHERE clause policy on the data source, Immuta returns the corresponding view expression as a WHERE clause. Otherwise, nothing is returned.
The Immuta plugin then requests policy information about the tables being queried from the Immuta Web Service and sends this information to the Trino Execution Engine. Finally, the Trino Execution Engine constructs the SQL statement, executes it on the backing tables to apply the policies, and returns the response to the user.
See the integration support matrix on the Data policy types reference guide for a list of supported data policy types in Starburst (Trino).
Users cannot bypass Immuta controls by changing roles in their system access control provider.
Multiple system access control providers can be configured in the Starburst (Trino) integration. This approach allows Immuta to work with existing Starburst (Trino) installations that already have an access control provider configured.
Immuta does not manage all permissions in Starburst (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.
If you have multiple access control providers configured, those providers interact in the following ways:
For a user to have access to a resource (catalog, schema, or a table), that user must have access in all of the configured access control providers.
In catalog, schema, or table filtering (such as show catalogs, show schemas, or show tables), the user will see the intersection of all access control providers. For example, if a Starburst (Trino) environment includes the catalogs public, demo, and restricted and one provider restricts a user from accessing the restricted catalog and another provider restricts the user from accessing the demo catalog, running show catalogs will only return the public catalog for that user.
Only one column masking policy can be applied per column across all system access control providers. If two or more access control providers return a mask for a column, Starburst (Trino) will throw an error at query time.
For row filtering policies, the expression for each system access control provider is applied one after the other.
See the Starburst (Trino) integration configuration page for instructions on configuring multiple access control providers.
Starburst (Trino) query passthrough is available in most connectors using the query table function or raw_query in the Elasticsearch connector. Consequently, Immuta blocks functions named raw_query or query, as those table functions would completely bypass Immuta’s access controls.
For example, without blocking those functions, this query would access the public.customer table directly:
select * from table(postgres.system.query(query => 'select * from public.customer limit 10'));
You can add or remove functions that are blocked by Immuta in the Starburst (Trino) integration configuration file. See the Starburst (Trino) integration configuration page for instructions.
An Immuta Application Administrator configures the Starburst (Trino) integration, adding the ImmutaSystemAccessControl plugin on their Starburst (Trino) node.
A data owner registers Starburst (Trino) tables in Immuta as data sources. A data owner, data governor, or administrator creates or changes a policy or user in Immuta.
Data source metadata, tags, user metadata, and policy definitions are stored in Immuta's Metadata Database.
A Starburst (Trino) user who is subscribed to the data source in Immuta queries the corresponding table directly in their Starburst catalog.
The Trino Execution Engine calls various methods on the interface to ask the ImmutaSystemAccessControl plugin where the policies should be applied. The masking and row-level security methods apply the actual policy expressions.
The Immuta System Access Control plugin calls the Immuta Web Service to retrieve policy information for that data source for the querying user, using the querying user's project, purpose, and entitlements.
The Immuta System Access Control plugin provides the SQL view expression (for masked columns) or WHERE clause SQL view expression (for row filtering) to the Trino Execution Engine.
The Trino Execution Engine constructs and executes the SQL statement on the backing catalogs and retrieves the data with appropriate policy enforcement.
User sees policy-enforced data.
The Starburst (Trino) integration supports the following authentication methods to create data sources in Immuta:
Username and password: You can authenticate with your Starburst (Trino) username and password.
OAuth 2.0: You can authenticate with OAuth 2.0. Immuta's OAuth authentication method uses the Client Credentials Flow; when you register a data source, Immuta reaches out to your OAuth server to generate a JSON web token (JWT) and then passes that token to the Starburst (Trino) cluster. If you use OAuth to authenticate when creating a data source, you must configure the globalAdminUsername property. See the OAuth authentication section for details.
Configure JWT authentication method in Starburst (Trino)
When using OAuth authentication to create data sources in Immuta, configure your Starburst (Trino) cluster to use JWT authentication, not OpenID Connect or OAuth.
When users query a Starburst data source, Immuta sends a username with the view SQL so that policies apply in the right context. Since OAuth authentication does not require a username to be associated with a data source upon data source creation, Immuta does not send a username and Starburst queries fail. To avoid this error, you must configure a global admin username.
If you are using OAuth or asynchronous authentication to create Starburst data sources, work with your Immuta representative to configure the globalAdminUsername property.
Immuta policies can be applied to Starburst (Trino)-created logical views.
The descriptions below provide guidance for applying policies to Starburst (Trino)-created logical views in the
However, there are other approaches you can use to apply policies to Starburst (Trino)-created logical views. The examples below are the simplest approaches.
DEFINER security modeFor views created using the DEFINER security mode,
ensure the user who created the view is configured as an admin user in the Immuta plugin so that policies are never applied to the underlying tables.
create Immuta data sources and apply policies to logical views exposing those tables.
lock down access to the underlying tables in Starburst (Trino) so that all end user access is provided through the views.
INVOKER security modeApplying policies to views or tables
Avoid creating data policies for both a logical view and its underlying tables. Instead, apply policies to the logical view or the underlying tables.
For views created using the INVOKER security mode, the querying user needs access to the logical view and underlying tables.
If non-Immuta table reads are disabled, provide access to the views and tables through Immuta. To do so, create Immuta data sources for the view and underlying tables, and grant access to the querying user in Immuta. If creating data policies, apply the policies to either the view or underlying tables, not both.
If non-Immuta table reads are enabled, the user already has access to the table and view. Create Immuta data sources and apply policies to the underlying table; this approach will enforce access controls for both the table and view in Starburst (Trino).
User impersonation: Native impersonation allows users to natively query data as another Immuta user. To enable native user impersonation, see the Integration user impersonation page.
Native query audit: Immuta audits queries run natively in Starburst (Trino) against Starburst (Trino) data registered as Immuta data sources.
The Immuta Trino Event Listener allows Immuta to translate events into comprehensive audit logs for users with the Immuta AUDIT permission to view. For more information about what is included in those audit logs, see the Starburst (Trino) audit logs page.
In addition to the information included on the Starburst (Trino) Audit Logs page, the audit logs payload in the Starburst (Trino) integration includes immutaPlanningDuration, which represents the planning overhead in Immuta.
You can configure multiple Starburst (Trino) integrations with a single Immuta tenant and use them dynamically. Configure the integration once in Immuta to use it in multiple Starburst (Trino) clusters. However, consider the following limitations:
Names of catalogs cannot overlap because Immuta cannot distinguish among them.
A combination of cluster types on a single Immuta tenant is supported unless your Trino cluster is configured to use a proxy. In that case, you can only connect either Trino clusters or Starburst clusters to the same Immuta tenant.
Limit your masked joins to columns with matching column types. Starburst truncates the result of the masking expression to conform to the native column type when performing the join, so joining two masked columns with different data types produces invalid results when one of the columns' lengths is less than the length of the masked value.
For example, if the value of a hashed column is 64 characters, joining a hashed varchar(50) and a hashed varchar(255) column will not be joined correctly, since the varchar(50) value is truncated and doesn’t match the varchar(255) value.
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.
The Starburst Cluster must be publicly accessible or have private connectivity configured.
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 Save.
If you are using OAuth or asynchronous authentication to create Starburst data sources, work with your Immuta representative to configure the globalAdminUsername property.
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 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.
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.

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 tenant used by Starburst (for example, https://my.immuta.tenant.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).
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.

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 Trino 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 Trino installations that have already configured an access control provider. 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.
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:

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 . This approach allows Immuta to work with existing Starburst installations that have already configured an access control provider.

For example, if the Starburst 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.
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 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.
