Hi George, If you PVCs could be mounted ReadWriteMany[1], then I think Flink could be deployed on these PVs. However, for the high availability enabled, you still need a distributed coordination system(ZooKeeper, or the new introduced Kubernetes HA[2]) for the leader election/retrieval and meta storage. The real data will be stored in the PV.
