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.
