Replicated event sourcing across two Akka Clusters

This may just work if we turn off the event publishing with cross reading but at least we should test and document.

I think this may end up being quite a common setup. For example, when the DCs have different Kubernetes clusters. In this scenario pods from the clusters may not be addressable and any communication may need to go via ingress. This won't work for Akka Cluster as we need peer to peer communication.

Sounds good to try this. So the db connection across two different Kubernetes cluster will work?

That would be a requirement. The database may or not be in the other k8s cluster. I think this is an easier requirement to satisfy then interpod communication across k8s clusters.
