@API(status=EXPERIMENTAL,
     since="1.7")
public static final String GLOBAL_KEY
```
    Key of the global resource lock that all direct children of the engine descriptor acquire in read mode by default.
    If any node requires an exclusive resource with the same key in read-write mode, the lock will be coarsened to be acquired by the node's ancestor that is a direct child of the engine descriptor and all of the ancestor's descendants will be forced to run in the same thread.
