Worked on targeted improvements across risingwavelabs/risingwave and risingwavelabs/risingwave-docs, focusing on documentation clarity and memory management. Enhanced the documentation by clarifying the usage of the --snapshot-ids flag for the delete-meta-snapshots command, making CLI operations more accessible for users. In the core repository, implemented a memory management update by increasing the maximum storage memory proportion and refining related configurations, which improved cache stability and prevented overflow. Collaborated on cross-repository changes to ensure alignment with project standards. Utilized Rust for system-level enhancements, Markdown for technical writing, and applied system design principles to deliver maintainable, user-focused improvements within one month.
