Worked on the TencentBlueKing/blueking-dbm repository to design and implement a robust repair workflow for MongoDB Mongos status, addressing reliability gaps and reducing downtime risk. The approach involved backend development using Django and Python, with a focus on REST API integration and workflow clarity. By renaming the MongoDB node status fix ticket type, the work improved traceability and maintainability within the codebase. All changes were carefully aligned with the review process, utilizing explicit commit messages and transaction IDs to enhance auditability. This effort strengthened incident response readiness and ensured that backend systems for status management were both clear and reliable.
