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 table management. They applied skills in API development, metadata management, and SQL to deliver features that reduced setup time and increased discoverability. In apache/incubator-gluten, they improved macOS build compatibility by conditionally disabling HDFS and adjusting type casting, enabling successful CI builds. Additionally, they introduced configurable column ordering for ModelViews in Kylin, making SQL generation more predictable. Their work demonstrated depth in backend development, build systems, and cross-platform configuration management using C++ and SQL.

November 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.
