Worked on enhancing the qiancai/docs repository by delivering targeted documentation clarifications for storage engine usage in slow query logs and statement summaries. Focused on improving the accuracy and clarity of technical content, the work detailed how Storage_from_kv and Storage_from_mpp indicate whether statements read from TiKV or TiFlash, directly supporting performance analysis and troubleshooting. Leveraged Markdown and documentation best practices to reduce ambiguity and strengthen user guidance around data paths in performance outputs. Collaborated cross-functionally to ensure changes were traceable and reproducible, ultimately supporting faster onboarding and more effective issue diagnosis for users interacting with storage engine analytics.
