## Highest ID

This example shows how to configure storing the HID file in *nscale Server Storage Layer*:

```yaml
global:
  # -- enables checking the highest DocID when starting the server.
  # this only makes sense, if you also set a separate volume for the highest ID
  # This is a backup / restore feature to avoid data mangling
  checkHighestDocId: "1"
  # -- sets the path of the highest ID file.
  dvCheckPath: "/opt/ceyoniq/nscale-server/storage-layer/hid"
```

We use the global section here to have it activated in all nstl instances defined.

This is used by the empty application sample and the ha sample.
