How can namespaces be used in Dgraph v25? I’m creating a dgraph client in Golang like this: `dgraphClient, err := dgo.NewClient(endpoint, dgo.WithNamespace(2))`, but when I then later on do queries or mutations the default namespace (`0`) is still used.

The namespace must already exist. And you’ll need to login that user via the client. See: [Multi-Tenancy - Dgraph](https://docs.hypermode.com/dgraph/enterprise/multitenancy#multi-tenancy)

and

So namespaces can only be used with ACL?

Practically, yes. Technically, no.

Over gRPC, you _could_ attach outgoing metadata `(namespace: <int>)` and queries and mutations would run in a non-ACL cluster. If all you’re doing is using gRPC, then fine. But of course, practically, other (non-gRPC) access to the cluster is probably desired (HTTP, Ratel, etc) which do not share the outgoing metadata mechanism that gRPC uses.
