Spring Data Couchbase 3.0 - Reactive examples

This project contains samples of reactive data access features with Spring Data (Couchbase).

Reactive Template API usage with RxJavaCouchbaseOperations

The main reactive Template API class is RxJavaCouchbaseTemplate, ideally used through its interface RxJavaCouchbaseOperations. It defines a basic set of reactive data access operations using RxJava 1 Single and Observable reactive types.

Airline airline = new Airline();

Observable<Airline> single = operations.save(airline)

Observable<Airline> airlines = operations.findByView(ViewQuery.from("airlines", "all"), Airline.class);

The test cases in RxJavaCouchbaseOperationsIntegrationTests show basic Template API usage. Reactive data access reads and converts individual elements while processing the stream.

Reactive Repository support

Spring Data Couchbase provides reactive repository support with Project Reactor, RxJava 1 and RxJava 2 reactive types. The reactive API supports reactive type conversion between reactive types.

@N1qlPrimaryIndexed
@ViewIndexed(designDoc = "airlines")
public interface ReactiveAirlineRepository extends ReactiveCrudRepository<Airline, String> {

    Mono<Airline> findAirlineByIataCode(String code);

    @View(designDocument = "airlines", viewName = "all")
    Flux<Airline> findAllBy();
}

@N1qlPrimaryIndexed
@ViewIndexed(designDoc = "airlines")
public interface RxJava1AirlineRepository extends Repository<Airline, String> {

    Single<Airline> findAirlineByIataCode(String code);

    @View(designDocument = "airlines", viewName = "all")
    Observable<Airline> findAllBy();

    Single<Airline> findById(String id);

    Single<Airline> save(Airline airline);
}
