Hi @ilpianista

Thanks so much for the contribution! Given we're planning important changes at #32958, I'll block this PR until the mentioned changes are landed.

I see. But wouldn't it be better to release this change earlier so as not to force everyone to upgrade to the major version with ClickHouse Keeper?

I don't think so given your changes don't require a new version since you're only modifying the default values that can be overriden while installing/upgrading the chart.

@ilpianista we just merged the PR replacing ZooKeeper with ClickHouse Keeper bumping the chart major version. Please refer to the upgrading notes to learn more about these changes.

Please note that now the default logging configuration is no longer in the values but in the ConfigMap below:

• https://github.com/bitnami/charts/blob/main/bitnami/clickhouse/templates/configd-configmap.yaml#L29-L34

As it's described in the README this logging configuration can be overriden by mounting a custom configuration file. For instance, using values like the ones below:

configdFiles:
  99-logger.xml: |
    <yandex>
        <logger>
            <level>none</level>
        </logger>
    </yandex>

Thanks so much for rebasing from main and adapting your changes! Please take a look to my suggestions when you have a chance.
