Worked on enhancing technical documentation for the taosdata/TDengine repository, focusing on the challenges of real-time, scalable time-series data management in IoT and Industry 4.0 environments. Updated the 02-concept.md file using Markdown to clarify how exponential data growth impacts storage and analysis, providing guidance for more accurate capacity planning and streamlined developer onboarding. Emphasized technical writing and documentation skills, ensuring that the new content is version-controlled and traceable through precise commit references. The work addressed the need for clear, maintainable documentation to support both new and existing developers as data volumes and system complexity continue to increase.
