PROFILE
Yan Xin
Over a two-month period, this developer enhanced apache/kylin by updating demo metadata files to streamline onboarding and implementing internal table filtering with extended OpenAPI endpoints, improving automation and integration workflows. They applied skills in metadata management, API development, and SQL to enable more efficient discovery and management of internal tables. In apache/incubator-gluten, they addressed macOS build compatibility by introducing conditional compilation in C++ and CMake, disabling HDFS dependencies to reduce build failures. Additionally, they improved SQL generation in Kylin by making column ordering configurable in ModelViews, resulting in more predictable and consistent data modeling outputs across environments.

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.
