Updates to models are not reflected after server restart

Data Services
1

After migrating to 2025.06 , I noticed that after I update my models (e.g. add some field to a document model), it’s not enough to restart the backend to see the changes, I also need to drop the existing Postgres database and start with a new one.

The strange thing is that the models seem to be updated in the database, but unless I am starting with a new database, I will be still getting the former ones.

Is there some configuration that I am missing or something like that?

One solution we found is to manually evict the cache using a migration task, but I really do not like it:

@Slf4j
@RequiredArgsConstructor
@MigrationStep(name = "Cache Eviction", version = "1.0.2", runAlways = true)
@Component
public class CacheEvictionMigration {
    private final ModelCacheManager modelCacheManager;

    @MigrationTask(name = "Cache Eviction")
    public void cleanCaches() {
        log.debug("Cleaining model cache");
        modelCacheManager.invalidateModelReadCaches("Sample-Model");
    }
}

Hi @i.ursu,

Updating of models should work without additional code. The caches should be invalidated automatically.

Can you please provide more information?

  1. How are you updating models ? init-app, initialization sequence of the dataservices-server-app, HTTP call
  2. How are you checking if the new version of model is available ? Are you checking in process via extension point, via HTTP request, call to the DS API ?
  3. What configuration do you use ?
  4. Do you use some extension points for updating of models?

I need answers to these questions so we would be able to reproduce it locally.

Thanks
