PROFILE
Xjxia
Over ten months, Xia worked on the TencentBlueKing/blueking-dbm repository, building and enhancing database high availability (DBHA) features to improve resilience, observability, and operational stability. Xia engineered robust failover logic, multi-slave switching for MySQL, and optimized API endpoints to streamline data retrieval and monitoring. By refactoring backend components in Go and SQL, Xia improved connection management, implemented SSH-based detection, and strengthened security through SQL injection prevention and host key verification. Xia’s technical approach emphasized distributed systems, concurrency control, and error handling, resulting in reduced downtime, faster recovery, and more reliable automated operations across the DBaaS infrastructure.
