SpringBoot Warn user when using parallelStream within a @Transactional DAO method

Enhancement: The user should be warned when using .parallelStream() in a method annotated with @Transactional

Consider the following example:

@Autowired
Repository  jpaRepo;

@Transactional
public void mySaveMethod( List records) {

   records.parallelStream().forEach( record ->
              jpaRepo.save(record)
    );

}

// Here the transaction boundary will be maintained per Parallel Thread. In some cases, user might require (and expect) a global transaction boundary which above method does not provide.

Transactional behavior of repositories is implemented by the various Spring Data projects, not by Spring Boot.

You can ask questions about Spring Data on StackOverflow or gitter, or file an issue in one of the Spring Data projects in Jira.
