Updating an Trino cluster

To change the cluster settings:

1. Go to the folder page and select Managed Service for Trino.

2. Select the cluster and click Edit in the top panel.

3. Under Basic parameters:

   • Edit the cluster name and description.

   • Delete or add new labels.

   • Select a service account or create a new one with the managed-trino.integrationProvider and storage.editor roles. The cluster will thus get the permissions it needs to work with user resources.

     To change your service account in a Managed Service for Trino cluster, make sure your Yandex Cloud account has the iam.serviceAccounts.user role or higher.

     Warning

     If the cluster already uses a service account to access objects from Object Storage, then changing it to a different service account may make these objects unavailable and interrupt the cluster operation. Before changing the service account settings, make sure that the cluster doesn't use the objects in question.

4. Under Network settings, select the cluster security group.

5. Change the configuration of the coordinator and workers.

6. Under Advanced settings, enable or disable cluster deletion protection.

7. Under Advanced settings, enable or disable logging. If logging is enabled, specify the log group or folder to write logs to and the minimum logging level.

8. Click Save changes.
