Worked on the apache/kudu repository to improve backend reliability by addressing a critical memory management issue in C++. Focused on stabilizing memory pressure evaluation within the ProceedWithFlush logic, the work involved correcting a unit mismatch by converting soft limits and pressure thresholds to percentages, ensuring alignment with the process_memory framework. The solution replaced division with multiplication for more accurate calculations and updated related tests to prevent regressions. All changes underwent thorough code review and validation before merging. This effort enhanced system stability under high memory usage, making memory-pressure decisions more predictable and consistent, with an emphasis on backend development best practices.
