Alauda Data Services Analytical Database E1

    • Upgrade

    There are two independent upgrades, and they are not the same operation:

    • The operator is upgraded by OLM, which replaces the operator's ClusterServiceVersion. This does not restart your database pods.
    • The operand — the ClickHouse® engine running in your clusters — is upgraded by changing the ClickHouseInstallation resource. This does restart database pods, one replica at a time.

    Upgrade the operator first. A newer operator is expected to manage an older operand; the reverse is not.

    If the Subscription was created with installPlanApproval: Automatic, OLM upgrades the operator as soon as a newer version appears in the stable channel. With Manual, an InstallPlan is created and waits for approval:
