Spring Data VS Spring Reactive Data

 With JPA 2.2, you no longer need to use converter it added support for the mapping of the following java.time types:

CrudRepository VS ReactiveCrudRepository

PagingAndSortingRepository VS  ReactiveSortingRepository

Flux<Person> findByLastname(Mono<String> lastname);

// insert

this.repository.save(product)
              .subscribe(p -> System.out.println("After inserting : " + p));

spring-boot-starter-data-r2dbc

@EnableTransactionManagement

@EnableJpaRepositories(basePackages = "com.baeldung.spring.data.persistence.repository")

 @Transactional annotation at the class level, which is then overridden for tRhe non-read-only methods.

Exception translation is still enabled by the use of the @Repository annotation on the DAO. This annotation enables a Spring bean postprocessor to advise all @Repository beans with all the PersistenceExceptionTranslator instances found in the container, and provide exception translation just as before.
