I have a history collection in MongoDB. I want to be able to save List of object in a single insertion. How can I do that?

For example, I have a repository as below

@Repository
public interface HistoryRepository extends MongoRepository<History, ObjectId>{
}

List myHistories = ArrayList…
When I try to save with HistoryRepository.saveAll(myHistories), it saves the list one by one. I want to know if there is a way to save myHistories with a single insertion command.

As I can see it’s possible in MongoDB docs but I couldn’t figure out with Java
