PROFILE
Yinghao Lin
Contributed to the apache/kylin repository by delivering backend features and maintenance focused on security, reliability, and compatibility. Developed a JDBC data source validation mechanism using Java and XML, introducing whitelist enforcement to strengthen configuration security and reduce misconfigurations. Upgraded key dependencies such as Spark, Gluten, and Calcite to maintain compatibility and access new features, leveraging build tools and version control best practices. Streamlined the API surface by removing deprecated endpoints and refactored code for clarity, while also improving unit test stability through dynamic version handling. Demonstrated a methodical approach to backend development, configuration management, and dependency maintenance throughout the project.

Sep 1, 2025September 2025: Focused on API surface cleanup and test stability improvements for apache/kylin. Delivered API cleanup by removing unused updateUser across RestClient.java and NUserController.java, deleted the update_user endpoint, and updated ignore-url lists in configuration to reflect the streamlined API surface. Fixed a unit test in ModelServiceTest by dynamically substituting the current Kylin version in the expected JSON, ensuring deterministic test results and reducing flaky failures.

Feb 1, 2025February 2025 monthly summary for Apache Kylin focusing on business value and technical achievements. Delivered a security- and reliability-enhancing JDBC data source improvement by implementing JDBC URL validation with whitelist enforcement. Added a new validator class and integrated it into the project service to validate configurations before use, reducing misconfigurations and strengthening data source security and robustness for downstream analytics workloads. This work consolidates the KYLIN-5994 fix (commit 21d98f3ef29f71b50dacabbf039905f9f0f71b95) and sets a foundation for safer data source integrations.
