### `UPDATE CONFIG`

Updates the configuration of the data instance/coordinator in the cluster.

```cypher
UPDATE CONFIG FOR ( INSTANCE instanceName | COORDINATOR coordinatorServerId ) configsMap=configMap ;
```

- **`instanceName` (string)** — the name of the data instance for which the configuration changes will be applied.
- **`coordinatorServerId` (int)** — previously registered coordinator ID for which the configuration changes will be applied.
- **`configsMaps` (int)** — Map of KV pairs that signal which field should be updated. Currently, it is only supported to update bolt server
of each instance.
