April 2026: Delivered Admin Error Message Refinement in GreptimeTeam/greptimedb. Removed redundant error messages in admin functions to streamline error handling and improve clarity for admins. The change reduces noise in admin reports, enabling faster diagnosis and fewer support escalations. This work is documented in commit 6c924efc2f91005f23e35fb207070bf822c81b64 (fix: remove redundant error messages in admin functions; closes #7938; relates to #7953). Impact: improved admin UX, easier maintenance, and safer troubleshooting with no API changes.
