Worked on the xupefei/delta repository with a focus on improving code quality and maintainability through targeted refactoring. Addressed a code formatting issue in Scala by standardizing the import order within the ConvertToHudiSuite.scala file, ensuring that related imports such as Eventually and SpanSugar followed project style guidelines. This formatting-only change did not alter any functional logic or runtime behavior but aimed to reduce future diff noise and simplify code reviews. By emphasizing consistent code structure and leveraging skills in code formatting and refactoring, the work contributed to a more maintainable codebase and streamlined onboarding for future contributors.
