Deployment for high-latency cross-region DR #41844

I've read the HA guides and see the requirement for a low-latency connection and synchronous database replication.

I'm interested in a cross-region DR solution where there is a high-latency and using asynchronous database replication. In this case, the "secondary" region would act as a standby, not taking any traffic while the "primary" site is active. There is no requirement to maintain login sessions between the KCs in the primary and secondary region - requiring a user to log in again after failover is acceptable.

So a couple of questions:

Is this sort of deployment possible?
What role, if any, would Infinispan play in this sort of deployment?
Does the KC in the secondary region need anything from the primary that is not replicated in the database (e.g. anything stored on the K8s environment)?

edit: replaced some uses of HA with DR as that is more reflective of what I'm asking
