Question. Could you share any docs for dirty checking for Spring ElasitcSearch Data

[codeleeks]

Hello. i'm testing spring-data-elasticsearch for my project.

recently it seems like spring-data-elasticsearch doesn't support dirty checking.

@Service
@Transactional
@RequiredArgsConstructor
public class PostIndexService {
    private final PostIndexRepository postIndexRepository;

    public void update(Post post) {
        PostIndex postIndex = postIndexRepository.findByPostId(post.getId())
                .orElseThrow(IllegalArgumentException::new);
        postIndex.setTitle(post.getTitle());
// without following line, it doesn't update fields in elastic search db.
//        postIndexRepository.save(postIndex)
    }

could you share any official docs about this dirty checking? i want to make sure it is true. i wonder if any misconfiguration might apply in my project.

Also, if you have time, please organize differences between RDB based spring data and spring-data-elasticsearch. i wonder if there are few more differences like this dirty checking. i want to avoid unnecessary debugging.

There is no dirty checking; a save call should send the data to Elasticsearch no matter if it existed before or not. How do you check if the document in Elasticsearch is modified? Have you any special refresh settings active? If this is reproducible provide a runnable minimal example that shows this behavior.
