я понимаю когда важно сохранять целостность важных данных и т.д
допустим у меня почти все модели которые хранят id-пользователей которые создали, меняли и т.д. насколько это важно
You should not assume that equal hash codes imply object equality.
You should never persist or use a hash code outside the application domain in which it was created, because the same object may hash across application domains, processes, and platforms.
