Worked on improving the documentation for Apache Paimon, specifically targeting Spark procedures to enhance clarity and accuracy for end users. Addressed an inconsistency in the procedures documentation by renaming the attribute from order_columns to order_by, ensuring alignment between the documentation and the actual system behavior. This update, implemented in Markdown, helped maintain consistency between code and documentation, which supports smoother onboarding and reduces potential confusion for users. Focused on documentation as the primary skill, the work contributed to the apache/paimon repository and demonstrated attention to detail in technical writing, ultimately supporting better user guidance and reducing support overhead.
