Worked on enhancing documentation for the TDengine repository, focusing on clarifying the data compression and storage workflow for time series data caching. Applied technical writing and documentation skills to update the 05-query.md file, ensuring the documentation accurately reflected the underlying implementation. Used Markdown to deliver clear explanations that align with the caching process, aiming to improve developer onboarding and reduce confusion around caching features. The work addressed common support queries by making the documentation more accessible and actionable for users. No bugs were fixed during this period, with efforts concentrated on documentation quality and technical accuracy for the TDengine project.
