Developed and delivered a feature for the ydb-platform/nbs repository enabling dynamic configuration of virtio queue counts through volume context attributes. This work focused on backend development and CSI driver integration, utilizing Go and Kubernetes to optimize per-volume performance and resource usage for both NBS and NFS backends. The implementation introduced constants for default and maximum queue counts, a vhost settings reader, and validation logic to prevent misconfiguration. Changes were integrated into the NodeStageVolume and NodePublishVolume operations, allowing for improved scalability and resource isolation. The solution addressed performance tuning needs in storage and system programming environments.
