It doesnt provide difference to reduce the storage.It provide differnce but that includes all the content so it will just increase the storage.

And the docs never claimed otherwise.

(If you want to store two similar documents space-efficiently by storing a base document in full and then just the diffs needed to generate the second, a good start might be to just delete the value properties from all non-insertion change objects, since deletions and no-op change objects can be applied without needing to know the value.)
