Updating Managed Service for Trino catalog settings

If you have a catalog in your Trino cluster, you can update the catalog’s settings.

Note

When you update a catalog, Managed Service for Trino recreates the cluster. While the new configuration is being applied, the cluster switches to Updating, and active queries get interrupted. For more information, see Updating a cluster.

  1. Open the TrinoCatalog resource file, e.g., using the open trinocatalog.yaml command.

  2. Edit the properties of the selected catalog type.

    General properties:

    • spec.<type>.url: Data source address
    • spec.<type>.additionalProperties: Advanced connector settings.

    For PostgreSQL and ClickHouse catalogs, the following properties are also available:

    • spec.<type>.credentialsSecretRef: Reference to the Secret with credentials.
    • spec.<type>.certificateSecretRef: Reference to the Secret with a TLS certificate.

    The spec.cluster, spec.name, and spec.type fields are immutable: spec.cluster and spec.name make up the resource name (metadata.name), and modifying spec.type is not supported.

    For Iceberg catalogs, the following properties are also available:

    • spec.iceberg.rest.warehouse: REST catalog name.
    • spec.iceberg.rest.oauth2: Authentication parameters (static token or client credentials).
    • spec.iceberg.s3: S3 storage settings.
    • spec.iceberg.stacklandStorage.bucketRef: Link to an Object Storage bucket.

  3. Apply the manifest: kubectl apply -f trinocatalog.yaml -n <namespace>.

If you store credentials in a Secret, update the Secret independently. You do not need to rename the secret name or keys.

  1. If you have not opened a project yet, select one.

  2. Select the namespace the cluster was created in.

  3. In the left-hand menu, select Trino → Clusters.

  4. Select the cluster and open the Catalogs tab.

  5. Select the catalog.

  6. Click Edit.

  7. Edit the catalog configuration under Catalog settings. The Name and Type fields are read-only.

    The Secret fields, such as Password, Access token, Client secret, and Secret access key, are empty. If you save them as is, the existing Secret values will remain unchanged. Enter a new value to update the secret.

    In the Additional settings section, the key is read-only for existing rows; you can only change the value. Still, you can add new keys.

  8. Click Save.

Done. The catalog settings have been updated.
