Worked on enhancing the stability of the StarRocks/starrocks data path by addressing a critical crash that occurred when scanning empty tablets with physical split enabled. The solution involved adding robust boundary checks in the C++ codebase to prevent out-of-bounds access when no rowsets were present, ensuring the system could gracefully handle empty-tablet scenarios. Comprehensive unit tests were introduced to validate these edge cases and reinforce reliability. Throughout the process, clear commit messages and adherence to CI and code review standards demonstrated a disciplined approach to debugging and collaboration, with a focus on code quality and maintainability using C++ and unit testing.
