Hello again. Great product. Do I understand correctly that in postgres mode etcd is still a must for cluster sync/state and postgresql is only used to store some metadata (file lists, stream stats)?

Thank you. There is no way to work without etcd or re-use etcd from kubernetes?

You can use external etcd cluster.
