Jens Schauder opened DATAJDBC-112 and commented

If an entity references another entity the referenced entity should get persisted with the original entity.

So:

 LegoSet set = new LegoSet("Awesome Truck");
 set.setManual(new Manual("Just plug everything together"));

 repository.save(set)

should result in two inserts. One into the table LegoSet, the other into the table Manual

#344 - Add support for support distinct derived query methods.
dd7c713 
We now support distinct derived queries that are useful with projections to retrieve distinct results.

interface UserRepository extends Repository<User, Long> {

  Mono<UserProjection> findDistinctByFirstName(String firstName);

}

interface UserProjection {

  String getFirstName();

}

#344 - Polishing.
8c0d01a 
Consider projection properties as SELECT projection. Refactor distinct() into marker method without accepting a boolean flag. Make distinct field final. Update tests.
