During May 2025, Alex Kuznetsov developed a feature for the ydb-platform/nbs repository that enables dynamic configuration of virtio queue counts through volume context attributes. This work involved implementing queue count constants, creating a vhost settings reader, and integrating these changes into the NodeStageVolume and NodePublishVolume operations for both NBS and NFS backends. By adding validation against maximum limits, Alex ensured robust misconfiguration prevention. The feature, written in Go and leveraging skills in backend and CSI driver development, allows for per-volume performance tuning and improved resource isolation, addressing scalability and efficiency requirements in Kubernetes-based storage environments.
