The how-to guides linked on this page illustrate how to integrate Starburst (Trino) with Immuta. See the reference guide for information about the Starburst (Trino) integration.
Connect your technology
These guides provide instructions on getting your data set up in Immuta for the Marketplace and Governance apps.
Configure your Starburst (Trino) integration: Install the Immuta Starburst (Trino) plugin in Starburst or Trino so that policies can be applied to data objects.
Register Starburst (Trino) data sources: This will register your data objects into Immuta and allow you to start dictating access through Marketplace or global policies.
Organize your data sources into domains and assign domain permissions to accountable teams: Use domains to segment your data and assign responsibilities to the appropriate team members. These domains will then be used in Marketplace, policies, audit, and identification.
Register your users
These guides provide instructions on getting your users set up in Immuta for the Marketplace and Governance apps.
Connect an IAM: Bring the IAM your organization already uses and allow Immuta to register your users for you.
Map external user IDs from Starburst (Trino) to Immuta: Ensure the user IDs in Immuta, Starburst (Trino), and your IAM are aligned so that the right policies impact the right users.
Start using Marketplace
These guides provide instructions on using Marketplace for the first time.
Publish a data product: Once you register your tables and users, you can immediately start publishing data products in Marketplace.
Request access to a data product: Users must then request access to your data products in Marketplace.
Respond to an access request: To grant access to a data product and its tables, respond to the access request.
Add data metadata
These guides provide instructions on getting your data metadata set up in Immuta for the Governance app.
Connect an external catalog: Bring the external catalog your organization already uses and allow Immuta to continually sync your tags with your data sources for you.
Run identification: Identification allows you to automate data tagging using identifiers that detect certain data patterns.
Start using the Governance app
These guides provide instructions on using the Governance app for the first time.
Author a global subscription policy: Once you add your data metadata to Immuta, you can immediately create policies that utilize your tags and apply to your tables. Subscription policies can be created to dictate access to data sources.
Author a global data policy: Data metadata can also be used to create data policies that apply to data sources as they are registered in Immuta. Data policies dictate what data a user can see once they are granted access to a data source. Using catalog and identification tags you can create proactive policies, knowing that they will apply to data sources as they are added to Immuta with the automated tagging.
Configure audit: Once you have your data sources and users, and policies granting them access, you can set up audit export. This will export the audit logs from user queries, policy changes, and tagging updates.
In this integration, Immuta policies are translated into Starburst rules and permissions and applied directly to tables within users’ existing catalogs.
This guide outlines how to integrate Starburst with Immuta.
Starburst (Trino) integration configuration guide: Configure the integration in Immuta.
Map read and write access policies to Starburst (Trino) privileges: Configure how read and write access subscription policies translate to Starburst (Trino) privileges and apply to Starburst (Trino) data sources.
Starburst (Trino) integration reference guide: This guide describes the design and components of the integration.
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:
accessGrantMapping:
WRITE: ['READ', 'WRITE', 'OWN']
READ: ['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. These permissions apply to all querying users except for administrators defined in immuta.user.admin (who get 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:
immuta.allowed.immuta.datasource.operations=READ,WRITE,OWN
immuta.allowed.non.immuta.datasource.operations=READ,WRITE,CREATE,OWNEnable 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,
access-control.config-files=/etc/starburst/immuta-access-control.propertiesCreate 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. These permissions apply to all querying users except for administrators defined in immuta.user.admin (who get 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:
immuta.allowed.immuta.datasource.operations=READ,WRITE,OWN
immuta.allowed.non.immuta.datasource.operations=READ,WRITE,CREATE,OWNEnable 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,
access-control.config-files=/etc/trino/immuta-access-control.propertiesThe 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).
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. Therefore, when using OAuth authentication to create data sources in Immuta, configure your Starburst (Trino) cluster to use JWT authentication, not OpenID Connect or OAuth.
The status of the integration is visible on the integrations tab of the Immuta application settings page. If errors occur in the integration, a banner will appear in the Immuta UI with guidance for remediating the error.
The definitions for each status and the state of configured data platform integrations is available in the response schema of the integrations API. However, the UI consolidates these error statuses and provides detail in the error messages.
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 modeFor 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: Impersonation allows users to query data as another Immuta user. To enable user impersonation, see the Integration user impersonation page.
Query audit: Immuta audits queries run 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.
Query audit is enabled by default on all Starburst (Trino) integrations, but you can disable it when configuring the integration with the following properties: immuta.audit.legacy.enabled and immuta.audit.uam.enabled.
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 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.

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.
access-control.name
392 and newer
Required
This property enables the integration.
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 . 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 complements existing controls. 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.
immuta.allowed.immuta.datasource.operations
413 and newer
Optional
This property defines a comma-separated list of allowed operations for Starburst (Trino) users on tables registered as Immuta data sources: READ,WRITE, and OWN. (See the for details about the OWN operation.) When set to WRITE, all querying users 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 are enabled for your Immuta tenant, this property is set to READ,WRITE by default, so users 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 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 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. To rotate this API key, use the to generate a new API key, and then replace the existing immuta.apikey value with the new one.
immuta.audit.legacy.enabled
435 and newer
Optional
This property allows you to turn off Starburst (Trino) audit. Must set both immuta.audit.legacy.enabled and immuta.audit.uam.enabled to false to fully disable query audit.
immuta.audit.uam.enabled
435 and newer
Optional
This property allows you to turn off Starburst (Trino) audit. Must set both immuta.audit.legacy.enabled and immuta.audit.uam.enabled to false to fully disable query audit.
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 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.http.timeout.milliseconds
464 and newer
Optional
The timeout for all HTTP calls made to Immuta in milliseconds. Defaults to 30000 (30 seconds).
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,
access-control.config-files=/etc/starburst/immuta-access-control.propertiesThe 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.

immuta.filter.unallowed.table.metadata=falseConfigure 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.

This property allows you to turn off Starburst (Trino) audit. Must set both immuta.audit.legacy.enabled and immuta.audit.uam.enabled to false to fully disable query audit.
immuta.audit.uam.enabled
435 and newer
Optional
This property allows you to turn off Starburst (Trino) audit. Must set both immuta.audit.legacy.enabled and immuta.audit.uam.enabled to false to fully disable query audit.
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 Trino. 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 Trino (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 Trino 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.http.timeout.milliseconds
464 and newer
Optional
The timeout for all HTTP calls made to Immuta in milliseconds. Defaults to 30000 (30 seconds).
immuta.user.admin
392 and newer
Required if immuta.group.admin is not set
This property identifies the Trino 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 Trino's configuration file (/etc/trino/config.properties for Docker installations or <trino_install_directory>/etc/config.properties for standalone installations). For example,
access-control.config-files=/etc/trino/immuta-access-control.propertiesThe 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.

# The administrator user regex. Starburst usernames matching this regex will not be subject to
# Immuta policies. This regex should match the user name provided at Immuta data source
# registration.
immuta.user.admin=immuta_system_account
# Optional argument (default is shown).
# A CSV list of operations allowed on schemas/tables registered as Immuta data sources.
immuta.allowed.immuta.datasource.operations=READ
# Optional argument (default is shown).
# A CSV list of operations allowed on schemas/tables not registered as Immuta data sources.
# Set to empty to allow no operations on non-Immuta data sources.
immuta.allowed.non.immuta.datasource.operations=READ,WRITE
# Optional argument (default is shown).
# Controls table metadata filtering for inaccessible tables.
# - When this property is enabled and non-Immuta reads are also enabled, a user performing
# 'show catalogs/schemas/tables' will not see metadata for a table that is registered as
# an Immuta data source but the user does not have access to through Immuta.
# - When this property is enabled and non-Immuta reads and writes are disabled, a user
# performing 'show catalogs/schemas/tables' will only see metadata for tables that the
# user has access to through Immuta.
# - When this property is disabled, a user performing 'show catalogs/schemas/tables' can see
# all metadata.
immuta.filter.unallowed.table.metadata=falseConfigure 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.
