Annotation Type IdempotencyKey

@Retention(value=RUNTIME)
 @Target(value=PARAMETER)
public @interface IdempotencyKey

@IdempotencyKey is used to signal that a method parameter is used as a key for idempotency.
Must be used in conjunction with the @Idempotency annotation.
Example:

     @Idempotent
     private MyObject subMethod(String param1, @IdempotencyKey String param2) {
         // ...
         return something;
     }
 

Note: This annotation is not needed when the method only has one parameter.
