how to handle http response streamly by vertx http client?

Question

@Slf4j
public class DownloadImg {


    private final WebClient webClient;
    private final Vertx vertx;

    public DownloadImg(Vertx vertx) {
        WebClientOptions newOptions = new WebClientOptions();
        newOptions.setDefaultPort(12345);
        newOptions.setDefaultHost("localhost");
        webClient = WebClient.create(vertx,newOptions);
        this.vertx = vertx;
    }

    public void download(String scm, String version) {

        String file = String.format("/%s_%s.tar.gz", scm.replace("/", "."), version);

        webClient.get("url_for_file")
                .send(it -> {
                    it.result();// i acully
                });

    }
}

I do get all the file data, but I want to handle those data by stream API in case the file is too large or OOM exception.

any idea?
