Springboot MVC - how to report status of long running HTTP request

Question

I am using Springboot MVC and say a HTTP call results in a long running operation :-

@PostMapping
public ResponseEntity<String> doSomething() throws IOException {
    this.someService.doLongRunningOperationSync(); //Long running operation. 
    return new ResponseEntity<>(org.springframework.http.HttpStatus.OK);
}

Now, how can I periodically update the client of the progress?

This draft - https://tools.ietf.org/id/draft-wright-http-progress-01.html - defines a way to report status of long running HTTP operations. Is something possible like this in springboot MVC? Any other alternative of how I can achieve this?
