# Connect to Starburst/Trino

Use the Starburst/[Trino](https://trino.io/docs/current/) Data Source to connect to an existing Starburst/Trino cluster. Once connected, you can use the Data Source to:

* Execute queries against the Starburst/Trino cluster using the data stores it’s connected to.

* Run Starburst/Trino federated queries supported by your Starburst/Trino cluster.

See the [list of Trino connectors](https://trino.io/docs/current/connector.html) Trino connectors for supported data stores.

You must have network connectivity between the Starburst/Trino cluster and your Domino deployment.

<Note>
  In a hybrid deployment, Trino Data Sources are only available in executions that use a hardware tier in the local [data plane](/cloud/platform-capabilities/core-concepts/zones/domino-nexus).
</Note>

## Create a Trino Data Source

Domino recommends that you use a [Domino Data Source](/cloud/platform-capabilities/core-concepts/data/data-source-connectors) to connect to a Trino instance.

1. From the navigation pane, click **Data > Data Sources**.

2. Click **Create a Data Source**.

3. In the New Data Source window, from **Select Data Store**, select **Trino**.

4. Enter the details about your Data Source and click **Next**:

   **Host**\
   The URL, hostname, or IP address of your Trino host.

   **Optional: Networking Proxy**\
   The URL (host and port) of your networking proxy that points to your Trino cluster, if applicable.

   **Port**\
   The port number for the connection, such as 443.

   **Catalog**\
   The name of the Trino catalog where your data is located. For example, if you plan to use the table `hive.test_data.test` then the catalog name is `hive`.

   **Optional: Schema**\
   The name of the Trino schema to use. For example, if you plan to use the table `hive.test_data.test` then the schema name is `test_data`.

   **Data Source Name**\
   The name that identifies the Data Source.

   **Optional: Data Source Description**\
   The purpose for the Data Source.

5. Specify the credentials for authenticating to Trino.

   Basic authentication is supported by default. The Domino secret store backed by HashiCorp Vault securely stores the credentials.

6. Click **Test Credentials**.

7. If the Data Source authenticates, click **Next**.

8. Select who can view and use the Data Source in projects.

9. Click **Finish Setup**.

## Next steps

* After connecting to your Data Source, learn how to [Use Data Sources](/cloud/platform-capabilities/core-concepts/data/data-source-connectors/use-data-sources).

* [Share this Data Source](/cloud/platform-capabilities/core-concepts/data/sharing-and-security/share-data-sources) with your collaborators.
