Worked on the ydb-platform/ydb repository to enhance memory accounting reliability for containerized workloads by implementing a robust Cgroup v2 memory limit access mechanism. Addressed edge cases where incomplete controller delegation or namespace path issues could cause incorrect memory limit reporting, introducing fallback logic to safely determine the correct memory.limit_in_bytes path. This solution reduced misreporting and improved system stability across diverse environments. The work involved close code collaboration and traceability, with changes linked to relevant issue tracking. Utilized C++ for system programming and advanced memory management, demonstrating a focused approach to solving low-level resource accounting challenges in complex container environments.
