Worked on the IBM/velox repository to deliver barrier-aware execution improvements, focusing on strengthening barrier-based pipelines and enhancing error diagnostics. Developed updates to the PlanFragment logic so that it now identifies and returns the first PlanNode lacking barrier execution support, resulting in clearer error messages and faster issue triage. Added barrier-aware execution support to the AssignUniqueId operator, increasing the robustness of data processing workflows. Addressed a correctness issue in AssertQueryBuilder by fixing vector loading in specific projection scenarios. Utilized C++ for operator development, debugging, and system design, demonstrating a methodical approach to improving reliability and maintainability in data processing systems.
