[FIXED] spring-data mongo repository. Is saveAll atomic?

Issue

I have a feeling that

org.springframework.data.mongodb.repository.MongoRepository#saveAll
/*
     * (non-Javadoc)
     * @see org.springframework.data.repository.CrudRepository#saveAll(java.lang.Iterable)
     */
    @Override
    <S extends T> List<S> saveAll(Iterable<S> entities);

is not atomic, is it true? It it possible to saveAll in single batch?

Solution

No, it's not. It saves in batch only "new" documents (checks by id). It saves existing documents (id is in collection) one by one.
