> AbstractBlob#equals tries to match content when length is equal and content identities is not null and different. Matching content triggers an expensive download of binaries for S3DataStore.
> Since, right now the content identity is the content hash the check can be short -circuited when the content identities is not null and not equal to return false.
> This can be revisited if we change the identity to something different.
