PROFILE
Hao Wu
Worked on the apache/cloudberry repository over three months, focusing on release process stability, test reliability, and performance optimization. Addressed integration-test failures by standardizing release artifact naming and aligning CI/CD pipelines, improving build reproducibility. Enhanced the disk quota testing framework using C, Makefile, and shell scripting, adding integration test switches, debugging aids, and performance monitoring to reduce flaky failures and speed up diagnosis. Optimized disk quota management with static inline functions and refined loop-time checks for better performance. Updated YAML-based release versioning to support 1.* tags, enabling more predictable releases and streamlined onboarding for downstream users and integrations.
