Java use of CompletableFuture with supply async

Question

Can someone review whether this code I have written makes sense? playing around with completableFutures

i have a DAO implementation which should return a CompletableFuture

public CompletableFuture<List<Info>> readFromDremio(Request request) {
  return CompletableFuture.supplyAsync(
    () -> dremioReferenceDAO.getData(req.date, req.nameList));
}

Then I want to take the result of the future and do some processing on it

public void handleResponse(Request request){
  CompletableFuture<List<Info>> infoFuture = dataHandler.readFromDremio(request);
 infoFuture.whenComplete(
        (info, ex) -> {
            if (ex == null) { 
                // do something with info
            } else {
                // handle exception
            }
 )
return;
}
