Hi, team.

Is there any way to configure # of FE observers in either FE config or via the helm charts (in addition of to the normal `replicas` for # of leader/follower.

In addition, could we deploy some FE observers in a backup DC / AZ for fast disaster recovery? Is this part of the design for Starrocks?

fe observer is not supported in starrocks operator deploy, neither crd nor helm chart.

Are there plan to support them at some point?

not in near future, but welcome to contribute from the community

I would love to help out on that. Is this something configurable however in the starrocks image somehow? via env var or FE config yaml?

So far I can see this process is only via a manual change after the cluster has been deployed <https://docs.starrocks.io/docs/administration/management/Scale_up_down/>.

Could I follow some existing design e.g. for FE or BE for that to happen?

observer doesn't participant the leader election, it shall be a separate statefulset apart from the existing fespec, and add/remove itself via `add/remove observer`

Thanks for the pointer, cannot guarantee anything yet, but will try to open a PR
