    3 - Altinity Kubernetes Operator 0.21.0 Release Notes

    clickhouse-operator 0.21.0 Release Notes

    What’s Changed

    • Changed the way Operator applies ClickHouse settings. In the previous version, every change in settings required a restart via re-creating a StatefulSet. In this version it does not re-create StatefulSet anymore, but maintains a logic that decide if ClickHouse needs to be restarted in order to pickup a change or not. In case of restart it is performed using scaling stateful set down and up. The restart logic is controlled by configurationRestartPolicy configuration setting. Here is the default configuration:
        rules:
      - version: "*"
        rules:
          - settings/*: "yes"
          - settings/dictionaries_config: "no"
          - settings/logger: "no"
          - settings/macros/*: "no"
          - settings/max_server_memory_*: "no"
          - settings/max_*_to_drop: "no"
          - settings/max_concurrent_queries: "no"
          - settings/models_config: "no"
          - settings/user_defined_executable_functions_config: "no"

          - zookeeper/*: "yes"

          - files/config.d/*.xml: "yes"
          - files/config.d/*dict*.xml: "no"

          - profiles/default/background_*_pool_size: "yes"
          - profiles/default/max_*_for_server: "yes"
      - version: "21.*"
        rules:
          - settings/logger: "yes"

    Fixed

    • Fixed a bug that might result in PDB being deleted
    • Fixed propagation of podTemplate environment variables from ClickHouseInstallationTemplate to ClickHouseInstallation
    • Fixed propagation of startup probe from ClickHouseInstallationTemplate to ClickHouseInstallation

    clickhouse-operator 0.18.0 Release Notes

    New features

    • k8s secrets can be referenced when defining user passwords. See 05-settings-01-overview.yaml.

    Changed

    • When CRD is deleted, operator keeps all dependent objects now (statefulsets, volumes). That prevents from incidental delete of a cluster.
    • When operator restarts it does not run a reconcile cycle anymore if CHI has not been changed. That prevents unneeded pod restarts. (Closes #855)
    • Operator configuration file format has been changed. See https://github.com/Altinity/clickhouse-operator/blob/0.18.0/config/config.yaml. Configuration in old format is supported for backwards compatibility.

    • Removed INFORMATION_SCHEMA from schema propagation. (closes #854)
    • Added a containerPort to metrics-exporter (#834)
