Save() operation doesn't seem to be synchronous [DATACOUCH-589]

murdos opened DATACOUCH-589 and commented

Using a non reactive repository, the following code in an integration test randomly fail, which make me think that then entity is not always saved when the save() method returns:

// Initialize the database
userRepository.save(user);
int databaseSizeBeforeCreate = userRepository.findAll().size();

assumeThat(databaseSizeBeforeCreate).isEqualTo(1); // assumption randomly fail with databaseSizeBeforeCreate being equal to 0

The getDefaultConsistency() method is gone from the AbstractCouchbaseConfiguration. I don’t know why. It could be added back, or we could introduce a Class-level @ScanConsistency annotation.

@mikereiche I’m trying to pick up where @murdos left off and upgrade JHipster’s Couchbase support to work with Spring Boot 2.4.2. You can see my in-progress PR here.

I feel like I’m overriding methods all over and added the following everywhere.

@ScanConsistency(query = QueryScanConsistency.REQUEST_PLUS)

However, I only really need this for tests, so it seems kinda weird.

Is there a mechanism in Spring Data Couchbase to make things strongly consistent like previous versions had? I’d only like it for tests so we can add/retrieve data successfully.

From https://stackoverflow.com/q/54897120/65681:

@TestConfiguration
@Slf4j
@Order(0)
public class TestCouchbaseConfig extends AbstractCouchbaseConfiguration {

    ...

    @Override
    protected Consistency getDefaultConsistency() {
        return Consistency.STRONGLY_CONSISTENT; //READ_YOUR_OWN_WRITES|UPDATE_AFTER ... etc;
    }
}
