PROFILE
Andrey Korzinev
Worked on the ydb-platform/nbs repository to deliver two backend and infrastructure features over a two-month period. Developed dynamic virtio queue configuration for CSI drivers, enabling per-volume performance tuning and resource isolation by reading queue settings from volume context and integrating validation against maximum limits. Later, added support for the NVIDIA Grace CPU target platform, introducing optimized compiler flags and compatibility workarounds for LLVM toolchains to ensure efficient code generation. The work involved backend development, system programming, and build systems, primarily using Go and Python, and focused on enhancing storage performance, scalability, and hardware compatibility without introducing any bug fixes.

May 1, 2025May 2025 monthly summary for ydb-platform/nbs: Delivered a feature to dynamically configure virtio queue counts via volume context to optimize per-volume performance and resource usage. Implemented queue count constants, a vhost settings reader, and integrated changes into NodeStageVolume and NodePublishVolume for NBS and NFS. Introduced validation against maximum limits to prevent misconfiguration. Commit 92b9da85eb6b184c905c906b61724acb1264a0f8 ('csi_driver: add volume context attribute to control number of virtio queues (#3425)').
