Aaron contributed to crossoverJie/starrocks by implementing an Iceberg orphan files cleanup feature, introducing a REMOVE_ORPHAN_FILES operation within IcebergTableOperation and enhancing IcebergAlterTableExecutor to remove unreferenced files based on snapshot lineage and an optional retention threshold. This backend development work, using Java and leveraging distributed systems concepts, improved storage hygiene and data governance by automating file lifecycle management. Additionally, Aaron addressed a documentation bug in apache/doris-website, updating Mac onboarding instructions to correct the LLVM version for Apple Silicon, thereby reducing setup failures. His work demonstrated depth in backend engineering, data engineering, DevOps, and technical documentation using Markdown.

Mar 1, 2025March 2025: Delivered Iceberg Orphan Files Cleanup for crossoverJie/starrocks. Implemented REMOVE_ORPHAN_FILES operation in IcebergTableOperation and added cleanup logic in IcebergAlterTableExecutor to remove files not referenced by any valid snapshot, with an optional older-than retention threshold. This reduces storage overhead and improves data hygiene with auditable retention rules. No critical bugs were fixed this month; changes include targeted tests and readiness for QA. Demonstrated skills in Iceberg metadata management, snapshot-based cleanup, and end-to-end change ownership.
