November 2024: Key deliverables include a Frontend configuration propagation regression fix in Doris (commit 9d7287504e24333a4e4a674ac7bad6cc4d1ebdb5) to ensure ADMIN SET ALL FRONTEND CONFIG propagates across all frontend nodes and prevents inconsistencies when the connected frontend is not the master, and a Data Partitioning Documentation Update in Doris Website (commit e8d2b6b86049600754a458d308354d5f359e2b17) reorganizing and clarifying basic concepts, manual/dynamic/auto partitioning, auto bucketing, and common issues. Business impact: improved cluster reliability and config consistency, reduced onboarding time and support queries due to clearer docs. Technical skills demonstrated: regression debugging, config administration, test stabilization, documentation engineering.

October 2024: Delivered end-to-end documentation for the Flexible Partial Update feature in Doris (apache/doris-website). The docs cover enabling and using the feature with Merge-On-Write Unique tables, configurations for Stream Load and Flink Doris Connector, applicable scenarios, usage examples, and known limitations. This work supports faster onboarding, clearer guidance for engineers and operators, and reduced support inquiries.
