|  | // A configuration group is a collection of key/value pairs which define how a | 
|  | // particular database operates. These key/value pairs are specific to each | 
|  | // datastore type and serve like settings. Some directives are capable of being | 
|  | // applied dynamically, while other directives require a server restart to take | 
|  | // effect. The configuration group can be applied to an instance at creation or | 
|  | // applied to an existing instance to modify the behavior of the running | 
|  | // datastore on the instance. |
