Multi-tenant horizontal scaling across Alphas

My primary use case for Dgraph revolves around multi-tenancy where I need to isolate each of my customer’s data within a separate tenant for security and compliance reasons, and as we grow we will require an increasing number of tenants. Different tenants will have different size datasets, and different levels of load, depending on the number of system users our customers have on-boarded to our service.

As we increase the number of tenants, we will likely need to scale horizontally to support the load; does Dgraph currently/are there any plans to support distributing tenants across nodes such that different Alpha nodes contain the entire data of, and are able to serve requests for, a subset of tenants, rather than all?

In the documentation I think I recall reading (though can’t find it now) that as Dgraph scales horizontally, replicating all data across all nodes such that any node can serve any request, but this would be undesirable in a multi-tenancy scenario, replicating every tenant’s data across every Alpha, due to the ever increasing storage requirements.
