Worked on the apache/datafusion-comet repository to enhance code quality and maintainability by addressing linting issues in critical data-path APIs. Focused on improving static analysis outcomes, the developer implemented an explicit Long return type for the number-of-rows API, aligning the interface with expected data scale and clarifying future data-path logic. Additionally, they used Scala and Java to suppress non-actionable compiler warnings on a stub through the @nowarn annotation, which contributed to more stable builds and reduced static analysis noise. Their efforts centered on code quality, linting, and Scala development, laying groundwork for future refactoring and improved code health.
