I understood it is possible to use Realm Sync on a (sometimes) offline application/client. This Realm Sync would manage the connection to the database along with conflict resolution. But, as I understood, Realm Sync would need to connect to an Atlas Cluster (a server).
I also understood here that offline is totally ok if Realm Sync is not used.
Is it possible to have an offline instance of that Atlas Cluster (i.e. not in the cloud)?
I need to build some database synchronisation for a project that will NEVER have access to internet.
