Hi Team, I’m running StarRocks 4.0.1 in Shared-Data mode on Kubernetes using the StarRocks Operator. All FE nodes currently show roles as LEADER or FOLLOWER. I attempted to convert one FE to an OBSERVER using commands like:

ALTER SYSTEM MODIFY FRONTEND "host:9010" TO OBSERVER;
ALTER SYSTEM MODIFY FRONTEND
    HOST "<fe-hostname>"
    TO OBSERVER;

but every variation fails with syntax errors (e.g., unexpected input ‘OBSERVER’, unexpected ‘PORT’, etc.). My question: 👉 Is OBSERVER role supported at all in StarRocks 4.x Shared-Data (S3) mode and Kubernetes Operator deployments? Or has it been deprecated and removed from the FE role model? If OBSERVER is not supported, what is the recommended alternative for reducing quorum load or adding read-only FE capacity?

👀

observer is supported in manual deployment, just can't add an operator-managed pod as observer.
