	public TestController(ProfileRepository profileRepository){
	  this.profileRepository = profileRepository;
	}
		
	@RequestMapping("/create-profile")
	@ResponseBody
	//Decode input in a non blocking fashion
	public Stream<Profile> createProfile(@RequestBody Stream<Profile> profiles) {
	  //transform input Profiles into saved Profile and pass them back in response
		return profiles.flatMap(profileRepository::save);
