Manage your Apache Airflow® cluster settings

  1. Go to the Clusters page.

  2. Find the Airflow® cluster you want to manage and click → Edit.

  3. Under Basic settings:

    1. Enter the cluster Name, in this scenario - tutorial-cluster.

    2. From the Version drop-down list, select the ClickHouse® version the Managed ClickHouse® cluster will use. For most clusters, we recommend using the latest version.

    3. Specify the GitHub repository address with your worker node configuration scripts.

  4. Under Web server networking:

    1. Under Networking → VPC, select the network where you want to create the cluster.

      If you don’t need to place the cluster in a specific network, leave the preselected default option.

    2. (optional) Add IP addresses or CIDRs allowed to access your cluster to the allowlist.

  5. Under Advanced settings:

    1. Under Maintenance settings, select between the arbitrary and scheduled maintenance:

      About maintenance settings

      If you select Arbitrary, DoubleCloud selects the maintenance window automatically. Usually, maintenance takes place at the earliest available time slot.

      Warning

      If your cluster has only one host, arbitrary maintenance can make it unavailable at a random time.

      To perform maintenance on a specific date and time, select By schedule and specify the day and time (UTC) when you want the cluster maintenance to be performed.

    2. Specify or adjust your cluster's DBMS settings. For more information, see the Settings reference.
