Worked on the apache/paimon repository to improve code quality by addressing documentation accuracy in the FieldCollectAgg class. Focused on correcting a typo in the class comment, changing 'dinstinct' to 'distinct' to ensure the documentation accurately described the intended aggregation behavior. This targeted update enhanced code readability and reduced potential confusion for future maintainers, supporting smoother onboarding for new contributors. The work involved careful code review and attention to detail, demonstrating a commitment to repository hygiene and long-term maintainability. Utilized Java as the primary language and applied code review skills to maintain high standards in core component documentation.
