PROFILE
Yan Xin
Worked on apache/kylin and apache/incubator-gluten, delivering features that improved onboarding, metadata management, and build stability. Enhanced Kylin’s onboarding experience by updating demo metadata and implemented internal table filtering with extended OpenAPI endpoints, enabling more efficient discovery and automation. In Gluten, addressed macOS build compatibility by conditionally disabling HDFS and adjusting type casting, reducing build failures and supporting macOS CI. Also introduced configurable column ordering for ModelViews in Kylin, making SQL generation more predictable. Demonstrated skills in C++, SQL, and configuration management, with a focus on backend development, conditional compilation, and maintaining clear traceability through disciplined commit practices.

Nov 1, 2024November 2024 (2024-11) monthly summary for apache/kylin focused on onboarding-ready metadata and enhanced internal table discovery. Delivered two features: 1) Kylin Demo Metadata Updates to refresh example metadata files for user onboarding and demonstrations; 2) Internal Table Filtering and API Enhancements to support filtering by database and table name (exact or fuzzy) and to extend OpenAPI endpoints to expose internaltable details. These changes are anchored by commits KYLIN-6027 (a7fd8bc2cf633e5fa8681187a004cdb53e8a12fe) and KYLIN-6053 (2ced2498338c7894cc6fdd115ce37121576472c6). Impact: reduced onboarding/setup time, improved internal-table discovery and management, and a stronger API surface for automation and integration. Technologies/skills demonstrated include metadata management, API design, OpenAPI, filtering logic, and release hygiene.
