Worked on the apache/celeborn repository to enhance dynamic resource management and deployment reliability in distributed environments. Developed features enabling the Celeborn client to update worker resources in real time by leveraging heartbeat-driven updates and refactoring the ChangePartitionManager, which improved resource utilization and resilience during partition revival. Further contributions included optimizing dynamic resource allocation by prioritizing existing worker candidates and reducing heartbeat load through RPC-based worker discovery, as well as clarifying deployment documentation for Spark, Flink, and MapReduce integrations. Demonstrated expertise in Java, distributed systems, and configuration management, with a focus on scalable, maintainable backend solutions and technical documentation.

Nov 1, 2024November 2024: Delivered two substantive improvements in apache/celeborn that enhance deployment reliability and runtime efficiency. Deployment Documentation Improvements clarified deployment instructions with exact client JAR file names for Spark, Flink, and MapReduce, reducing onboarding errors and ambiguity. Dynamic Resource Allocation Optimization refactored client resource usage to prioritize existing worker candidates, reduced heartbeat load by moving available worker discovery to the requestSlots RPC, and introduced clientShuffleDynamicResourceFactor to tune dynamic resource requests. These changes improve scalability, lower operational risk, and provide tunable controls for workload-driven resource management.

Oct 1, 2024Month: 2024-10. Focused on delivering dynamic worker resource updates in the Celeborn client to improve resource utilization and resilience. Implemented changes in ChangePartitionManager so that newly reported workers from heartbeats are considered during partition revival, enabling more efficient resource allocation and faster recovery in the face of fluctuating worker availability. This work is tied to CELEBORN-1636 ([commit 7685fa7db22a156d42f8824192ccd6264d351de7]: Client supports dynamic update of Worker resources on the server). Major bugs fixed: none reported this month. Overall impact: improved scaling and fault tolerance for Celeborn workloads; increased server utilization efficiency and robustness during dynamic cluster changes. Technologies/skills demonstrated: Java, client-server resource management, heartbeat-driven resource awareness, ChangePartitionManager refactoring, emphasis on resilience and performance in distributed systems.
