Bumped version number to 2.0. Upgraded to Spring Boot 2.0. Stuff disabled in the meantime: - Cassandra: needs API adaptions in configuration - JPA > Security: test fails with weird Hibernate error - Redis > Reactive: API updates needed - Solr: configration updates necessary adjust versions Updated elastic search to the new version. Fixed the reactor version to Bismuth-BUILD-SNAPSHOT. This probably should be undone when boot references the proper bom.
Spring Data Cassandra - Java 8 examples
This project contains samples of Java 8 specific features of Spring Data (Cassandra).
Support for JDK 8's Stream for repository methods
Repository methods can use a Java 8 Stream as a return type which will cause the reading of the results and the to-object-conversion of rows to happen while iterating over the stream.
public interface PersonRepository extends CrudRepository<Person, String> {
@Override
List<Person> findAll();
// Derived query method returning a Java 8 Stream
Stream<Person> findAll();
}
The test cases in PersonRepositoryIntegrationTest oppose a plain List based query method with one that uses a Stream and shows how the former pulls all data into memory first and the iteration is done over the pre-populated list. The execution of the Stream-based method in contrast shows that the individual elements are read and converted while iterating the stream.
