enabling multi-customer apps without the overhead of managing a database per
customer.

The default namespace is created when the cluster is provisioned. It is named
`root`.

Namespace APIs are part of the [v2 APIs](#v2-apis). The v2 APIs are available in
the `dgo/v250` package today. Other SDKs are being updated currently.

To create a namespace, use the `CreateNamespace` function.

```go
err := client.CreateNamespace(context.TODO(), "finance-graph")
namespaceID, err := client.CreateNamespace(context.TODO())
// handle error
fmt.Printf("%d\n", namespaceID)
// handle error
```

You can now pass this name to `SetSchema`, `RunDQL` or similar functions.

### Dropping a namespace

To drop a namespace, use the `DropNamespace` function.

```go
err := client.DropNamespace(context.TODO(), "finance-graph")
// handle error
```

### Rename a namespace

To rename a namespace, use the `RenameNamespace` function.

```go
err := client.RenameNamespace(context.TODO(), "finance-graph", "new-finance-graph")
err := client.DropNamespace(context.TODO())
// handle error
```
