OptimisticLockingFailureException is now thrown only when deleting an entity through a repository and no longer when using the Template API.
Original pull request: #641.
We now consider a potential @Version when removing an entity.
MongoOperations#remove(Object) and MongoOperations#remove(Object, String) include the version of the object to remove if the entity is versioned. Opposed to save(Object), remove(Object) does not throw OptimisticLockingFailureException if a versioned entity could not be removed. This behavior is subject to be changed in a future release. Throwing OptimisticLockingFailureException on failed delete on Template API level was not introduced to not break existing application code.
MongoRepository now also considers the entities version, following the very same logic as MongoOperations.
To remove an entity without version check use MongoOperations#remove(Query,…) or MongoRepository#deleteById(…).

We now support reactive GridFS using MongoDB's reactive GridFS API. Files can be consumed and provided as binary stream.
ReactiveGridFsOperations operations = …;
Publisher<DataBuffer> buffers = …
Mono<ObjectId> id = operations.store(buffers, "foo.xml");
Flux<DataBuffer> download = operations.getResource("foo.xml").flatMap(ReactiveGridFsResource::getDownloadStream);

ReactiveMongoTemplate.insert(…) now uses the saved entity when emitting AfterSaveEvent. This change affects usage of immutable objects that are using Id generation. Previously, the to-be-saved entity instance was used which left the Id unpopulated.

Introduce base class for common Querydsl query execution tasks that can be used for imperative and reactive implementation.
Fix test issues due to context caching where indices are not recreated when dropping the collection during test setup.
Update reference documentation.
Original Pull Request: #635
We now support execution of Querydsl Predicates using reactive MongoDB repositories. Reactive repositories are only required to add ReactiveQuerydslPredicateExecutor to their declaration to enable Querydsl.
public interface PersonRepository extends ReactiveMongoRepository<Person, String>, ReactiveQuerydslPredicateExecutor<Person> {
// additional query methods go here
}
PersonRepository repository = …;
QPerson person = new QPerson("person");
Flux<Person> result = repository.findAll(person.address.zipCode.eq("C0123"));

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.
Original Pull Request: #636
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);
Original Pull Request: #636
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.

MetadataBackedField no longer fails when Path detects reference to field within java.lang.Class. This can happen when splitting the property name via camel case where the first part matches to class which resolves to the getClass() call on java.lang.Object. When then the 2nd part also maps to a method (like getName()) on Class an error would be thrown.
Original Pull Request: #631
QueryMapper now excludes the type key in during mapping and retains the value as-is. This change fixes an issue in which type keys were attempted to be mapped using the entity model. Type key resolution for _class failed silently while other type keys such as className failed in property path resolution and the failure became visible.
Original Pull Request: #631
We now make sure that mapped updates (as in doSaveVersioned and doUpdate) are mapped only once as mapping is required only once. Mapping already mapped query/update objects comes with undesired side-effects such as following invalid property paths or reduction of type information availability.
We now make sure to map key/value pairs of Map like properties to the values domain type, and apply potentially registered custom converters to the keys.
Fixed invalid test for DATAMONGO-1423 as this one did not check the application of the registered converter.

Set interrupted thread state after catching InterruptedException. Fix potential NPE by checking the cursor. Streamline generics to not hide class-level generic types.
Original pull request: #634.
We now make sure to translate and pass on errors during the cursor initialization procedure to the configured error handler.
Original pull request: #634.
MetadataBackedField.getPath() now returns null instead throwing an error for fields that are not part of the domain model. This allows adding any field when updating an entity.

The previous implementation of (Reactive)MongoTemplate.doInsertBatch(…) prematurely initialized the version property so that the entity wasn't considered new by the auditing subsystem. Even worse, for primitive version properties, the initialization kept the property at a value of 0, so that the just persisted entity was still considered new. This mean that via the repository route, inserts are triggered even for subsequent attempts to save an entity which caused duplicate key exceptions.
We now make sure we fire the BeforeConvertEvent before the version property is initialized or updated. Also, the initialization of the property now sets primitive properties to 1 initially.

We now consider the collection name that is bound to the repository when inserting entities of which all are new. Previously, the collection name was derived from the entity.

Use ObjectUtils to compote hash code as hash code implementation contained artifacts that do not belong there. Extract test method.
Original pull request: #629.
We now return null instead of an empty string when calling IndexInfo#getPartialFilterExpression. The method has been marked to return null vales before and we’re complying to that contract and return value expectation.

Rename NestedProperty to KPropertyPath to reflect the underlying concept in alignment with our own PropertyPath type. Rename nestedFieldName(…) method to asString(…) to align with Kotlin method terminology. Reformat.
Slightly reword documentation. Add Type-safe Queries for Kotlin to What's New section.
Original pull request: #622.
We now support type-safe queries using Kotlin's DSL capabilities by accepting property references. Property references map to property paths and are translated to Criteria objects.
mongoOperations.find<Book>(
Query(Book::title isEqualTo "Moby-Dick")
)
mongoOperations.find<Book>(
Query(Book::title exists true)
)
mongoOperations.find<Book>(
Query(Criteria().andOperator(
Book::price gt 5,
Book::price lt 10)
))
