> There is a problem with Geode WAN replication when GW receivers are
> configured with the same hostname-for-senders and port on all servers. [ 1 ]
> The problem experienced is that shutting down one server is stopping
> replication to this cluster until the server is up again. This is because
> Geode incorrectly assumes there are no more alive servers when just one of
> them is down, because since they share hostname-for-senders and port, they
> are treated as one same server.
> Our proposal consists on expanding internal data in locators with enough
> information to distinguish servers in the beforementioned use case. The same
> intervention is likely needed in the client pools and possibly elsewhere in
> the source code.
> ----
> [ 1 ] : The reason for such a setup is deploying Geode cluster on a
> Kubernetes cluster where all GW receivers are reachable from the outside
> world on the same VIP and port. Other kinds of configuration (different
> hostname and/or different port for each GW receiver) are not cheap from OAM
> and resources perspective in cloud native environments and also limit some
> important use-cases (like scaling).
