Worked on the Altinity/ClickHouse repository to improve documentation accuracy for the URL Table Engine by removing incorrect guidance about the unsupported 'PARTITION BY' feature. Addressed a documentation bug by updating both English and Japanese Markdown files, ensuring consistency and clarity across languages. Focused on aligning the documentation with the actual engine capabilities, this change helps users avoid misconfiguration and reduces potential support requests. The work required careful attention to multilingual documentation standards and precise technical communication. By refining the documentation, contributed to a smoother onboarding experience for users evaluating the URL engine and enhanced the overall reliability of project resources.
