Auto-index creation can now be disabled by setting MongoMappingContext.setAutoIndexCreation(false). This configuration prevents automatic index creation on application startup and during access to entities. Auto-index creation comes with automated collection creation. Users that rely on collection creation (e.g. if you wish to use ClientSessions or transactions) must make sure the collection exists prior to session usage.
We now provide IndexResolver to resolve and derive index definitions from Mongo entities. MongoMappingContext mappingContext = new MongoMappingContext(); IndexResolver indexResolver = IndexResolver.create(mappingContext); Iterable<? extends IndexDefinitionHolder> definitions = indexResolver.resolveIndexFor(MyEntity.class);

Undo deprecation and transition to configuration option allowing to disable the index creation. Index creation will remain in the codebase as it is used in a lot of places to configure required geo index structures in MongoDB without which query execution would fail.

We now deprecate the auto-index creation feature as automatic index creation has created a lot of downstream issues.
We also introduce a configuration flag to disable auto-index creation through MongoMappingContext.setAutoIndexCreation(false).
Lastly, we're exposing
IndexResolverto allow application code to derive index definitions from annotated entities.Related ticket: DATAMONGO-2188.
