We now support hashed index definitions via IndexOperations. Reading index information back allows to identify a hashed index via isHashed().
Original pull request: #750.
OutOperation now supports the expanded format for the $out aggregation operation if additional parameters, next to the target collection, are given.
Aggregation.out("out-col").insertDocuments().in("database-2").uniqueKey("field-1“);
{
$out : {
to : "out-col",
mode : "insertDocuments",
db : "database-2",
uniqueKey : "field-1"
}
}
We’ll stick to the 2.6 format if only a collection name has been set.
Aggregation.out("out-col“);
{ $out : "out-col" }

We now make sure to call the delegate AggregationOperationContext without potentially overriding arguments. Without this change potentially registered target types would be overridden with null.
We now apply propagate the cursor size to aggregation options. We introduced AggregationOptions.comment to propagate the meta comment to aggregation execution.

Use MongoQueryMethod.getDomainClass() instead of getRepositoryDomainType(). Simplify annotation presence indicator methods hasAnnotatedSort() and hasAnnotatedCollation(). Refactor getAnnotatedAggregation() to non-nullable method throwing IllegalStateException to be consistent with other getXxx() methods.
Simplify aggregation execution and consider collection/single element declaration for reactive execution.
Tweak docs.

Reuse collection name for index creation instead of resolving the collection for every index. Switch lambda to method reference.
Original pull request: #746.
We now lazily read the collection of an entity as it potentially requires a more expensive SpEL evaluation that might not have been required in fist place.

Fix count operation inside transaction and avoid superfluous client session instantiation.
Default MongoDatabase emission in case of non active transaction, update documentation, move test to another package.
Delay reactive collection re/creation in test to cope with issues in server version 4.1.10.

Support declarative reactive transaction via the Transactional annotation via a MongoDB specific ReactiveTransactionManager implementation.
@Bean
ReactiveMongoTransactionManager transactionManager(ReactiveDatabaseFactory factory) {
return new ReactiveMongoTransactionManager(factory);
}
@Component
public class StateService {
@Transactional
Mono<UpdateResult> someBusinessFunction(Step step) {
return template.insert(step)
.then(process(step))
.then(template.update(Step.class).apply(Update.set("state", …));
};
});

Store result to getPersistentEntity() in local variable to reduce invocation count. Use numbered postfix instead of object instantiation to generate a unique distance field name.
Deprecate geoNear methods with hint to aggregations. Fix distance field usage in ReactiveMongoTemplate.
Tweak docs.
Original pull request: #744.
Deprecate and guard tests for removed commands:
- eval
- group
- maxScan
- geoNear
Transition from removed geoNear command to $geoNear aggregation pipeline stage.
This allows users to still use NearQuery along with the template that now transforms the query into a GeoNearOperation applying skip (previously in memory skipping) and limit (previous num parameter) as additional aggregation pipeline stages.
Tested against:
- 4.1.10
- 4.0.4
- 3.6.12
- 4.4.20

The collation can now also be configured on entity level and gets applied via MongoTemplate. However one can alway override a default collation by adding the collation explicitly to either the Query or one of the Options available for various operations.
When it comes to the repository level the hierarchy is method parameter over query annotation over entity metadata.
Remove collation annotation in favor of attributes of Query / Document.
Original pull request: #644.
We now allow to specify the collation via the @Query annotation.
public interface PersonRepository extends MongoRepository<Person, String> {
@Query(collation = "en_US")
List<Person> findByFirstname(String firstname);
@Query(collation = "{ 'locale' : 'en_US' }")
List<Person> findPersonByFirstname(String firstname);
@Query(collation = "?1")
List<Person> findByFirstname(String firstname, Object collation);
@Query(collation = "{ 'locale' : '?1' }")
List<Person> findByFirstname(String firstname, String collation);
List<Person> findByFirstname(String firstname, Collation collation);
}
We now make sure to include collation information derived from the Query method if the collation is a fixed value.

Align Indexed(expireAfter) default to empty string according to the documentation. Slightly reword Javadoc.
Import DurationStyle to reuse duration parsing until Spring Framework provides a similar utility. Document ISO-8601 duration style. Prevent null index name evaluation to render "null" as String.
Convert assertions from Hamcrest to AssertJ.
Original pull request: #647.
We now also evaluate SpEL expressions for the name of indices as well as the def attribute of the compound index definition.
@CompoundIndex(name = "#{'cmp' + 2 + 'name‘}“, def = "#{T(org.bson.Document).parse(\"{ 'foo': 1, 'bar': -1 }\")}")
class WithCompoundIndexFromExpression {
// …
}
An expression used for Indexed.expireAfter may now not only return a plain String value with the timeout but also a java.time.Duration.
Original pull request: #647.
We added expireAfter which accepts numeric values followed by the unit of measure (d(ays), h(ours), m(inutes), s(econds)) or a Spring template expression to the Indexed annotation.
@Indexed(expireAfter = "10s")
String expireAfterTenSeconds;
@Indexed(expireAfter = "1d")
String expireAfterOneDay;
@Indexed(expireAfter = "#{@mySpringBean.timeout}")
String expireAfterTimeoutObtainedFromSpringBean;
