* Annotation for marking a hash key or range key property in a class to
* auto-generate this key. Only String typed keys can be auto generated, and are
* given a random UUID. The annotation can be applied to either the getter
* method or the class field for the auto-generated key property. If the
* annotation is applied directly to the class field, the corresponding getter
* and setter must be declared in the same class. This annotation can be applied
* to both primary and index keys.
