Worked on reliability and documentation improvements for the apache/seatunnel project, focusing on backend development and data engineering with Java and Apache Iceberg. Addressed data integrity issues in the Iceberg connector by implementing atomic per-checkpoint commits, preventing duplicate snapshots during parallel writes. Enhanced the Log API to correctly handle per-node REST ports and log link URLs in multi-node deployments, validated through expanded integration testing. In addition, improved technical documentation by correcting configuration key names, reducing user confusion and misconfigurations. The work emphasized robust testing, clear technical writing in Markdown, and careful attention to production stability and user onboarding experience.

Apr 1, 2026April 2026: Reliability and correctness improvements across Seatunnel's Iceberg integration and multi-node logging. Implemented atomic per-checkpoint commits to guarantee data integrity during parallel writes, and fixed the Log API to return each node's REST port with per-node log link URLs in multi-node deployments. Expanded test coverage with integration tests to validate multi-node behavior and end-to-end log retrieval. These changes reduce data duplication risk, improve observability, and strengthen production stability.
