During December 2025, Dongdong Du contributed to the apache/amoro repository by developing two core backend features focused on reliability and scalability. He built a Process Scheduling Framework for the Process Service, refactoring the existing table process logic and introducing targeted optimizations and expanded test coverage. Additionally, he implemented a Database High Availability Service with Leader Election, enabling automatic failover and configurable HA types and heartbeat intervals. Using Java and leveraging skills in backend development, database management, and scheduling algorithms, Dongdong’s work reduced downtime risk, improved throughput under load, and established a robust foundation for future scaling and operational resilience.
