Configure Starburst (Trino) Integration

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.

Starburst Cluster Configuration

Requirements

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.

1 - Enable the Integration

Click the App Settings icon in the left sidebar.
Click the Integrations tab.
Click Add Native Integration and select Trino from the Native Integration Type dropdown menu.
Click Save.

OAuth Authentication

If you are using OAuth or asynchronous authentication to create Starburst data sources, work with your Immuta representative to configure the globalAdminUsername property.

2 - Configure the Immuta System Access Control Plugin in Starburst

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.

Property Starburst version Required or optional Description

Property	Starburst version	Required or optional	Description
`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 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 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 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. To rotate this API key, use the Integrations API to generate a new API key, and then replace the existing `immuta.apikey` value with the new one.
`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.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

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 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 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. To rotate this API key, use the Integrations API to generate a new API key, and then replace the existing immuta.apikey value with the new one.

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.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.properties
```

Example Immuta System Access Control Configuration

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.

# Enable the Immuta System Access Control (v2) implementation.
access-control.name=immuta

# The Immuta endpoint that was displayed when enabling the Starburst integration in Immuta.
immuta.endpoint=http://service.immuta.com:3000

# The Immuta API key that was displayed when enabling the Starburst integration in Immuta.
immuta.apikey=45jdljfkoe82b13eccfb9c

# 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=false

3 - Add Starburst Users to Immuta

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.

Trino Cluster Configuration

1 - Enable the Integration

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.

OAuth Authentication

If you are using OAuth or asynchronous authentication to create Starburst data sources, work with your Immuta representative to configure the globalAdminUsername property.

2 - Configure the Immuta System Access Control Plugin in Trino

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.

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:
- Docker (Trino 413 and older)
  1. Follow Trino's documentation to install the plugin archive on all nodes in your cluster.
  2. Create the Immuta access control configuration file in the Trino configuration directory: /etc/trino/immuta-access-control.properties.
- Docker (Trino 414 and newer): For Trino versions 414 and newer, you can use the `immuta-trino` Docker image (which includes the Trino plugin jars) from registry.immuta.com instead of the trinodb/trino Docker image.
  1. Pull the image and start the container. The example below specifies the Immuta Trino plugin version 414 with the 414 tag, but any supported Trino version newer than 414 can be used:
    docker run registry.immuta.com/immuta/immuta-trino:414
  2. Create the Immuta access control configuration file in the Trino configuration directory: /etc/trino/immuta-access-control.properties.
- Standalone installations
  1. Follow Trino's documentation to install the plugin archive on all nodes in your cluster.
  2. Create the Immuta access control configuration file in the Trino configuration directory: <trino_install_directory>/etc/immuta-access-control.properties.
