Re: Flink on block storage in k8s

[George Costea]

Hi there,

Can flink be deployed to PVCs backed by block storage?  It seems the
only option is blob storage today.

Thanks,
George

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.

Best,

Yang
