Worked on the QuestDB documentation repository to address a critical documentation bug affecting Parquet data workflows. Identified and corrected a mismatch between the documented and actual API function names, updating references from parquet_read to read_parquet to ensure users interact with Parquet files correctly. This change, implemented using Markdown and documentation best practices, improved the accuracy and reliability of user guidance. By aligning the documentation with the codebase, the update reduced potential user confusion and support requests. The work demonstrated careful attention to detail, effective use of version control, and a commitment to maintaining high-quality, consistent technical documentation for end users.
