In our ongoing SIG Spotlight series, we shine a light on the groups that keep the Kubernetes project moving forward. This time, we catch up with SIG Storage , the group responsible for persistent data, volume management, and the interfaces that connect Kubernetes workloads to the storage systems beneath them.
We spoke with Xing Yang , Co-Chair of SIG Storage and Software Engineer at VMware by Broadcom, about the SIG’s history, the features shipping in recent Kubernetes releases, and where storage in Kubernetes is headed as AI workloads become the norm.

An interview with Xing Yang, Co-Chair of SIG Storage, covering the group's history, current work, and roadmap. Key highlights include VolumeGroupSnapshot reaching GA in Kubernetes v1.36, CSI Changed Block Tracking (CBT) moving to Beta, and the Container Object Storage Interface (COSI) transitioning to v1alpha2. The discussion also covers ongoing challenges with stateful workloads — data gravity, Day 2 complexity, and data mobility — and how storage in Kubernetes is evolving to support AI/ML workloads through smarter CSI drivers, object storage standardization via COSI, high-performance parallel file systems, and data-aware scheduling.
