Realm 모바일 데이터베이스는 가능한한 타입과 구조 변환을 최소화하여 객체를 직접 디스크에 유지합니다. 복잡한 엔티티에 대한 매핑 등 신속히 처리해야 할 다른 문제가 없으므로, Realm 모바일 데이터베이스는 메모리 상의 오브젝트를 디스크로 빠르게 가져올 수 있습니다.

// 백그라운드에서 비동기적으로 갱신합니다
realm.executeTransactionAsync(new Realm.Transaction() {
@Override
public void execute(Realm bgRealm) {
Dog dog = bgRealm.where(Dog.class).equalTo("age", 1).findFirst();
dog.setAge(3);
}
}, new Realm.Transaction.OnSuccess() {
@Override
public void onSuccess() {
// 원래 질의와 Realm 객체는 자동으로 갱신됩니다
puppies.size(); // => 0. 2살 미만의 강아지가 더 이상 없기 때문에
managedDog.getAge(); // => 3. 강아지의 나이가 갱신되었습니다
