Multiple Try and nested async's

[anonymous1654]

I have an existing async called wrapped inside a Try and working with Futures.sequence

e.g.

List<CompletableFuture<Try<Foo>>> requests = [...]
CompletableFuture<List<Try<Baz>>> items = Futures.sequence(requests);
List<Try<Baz>> result = items.join()
.stream()
.map(try -> myFunction(try))
.collect(Collectors.toList())

...

private Try<Baz> myFunction(Try<Foo> fooTry) {
    return fooTry.flatMap(foo -> Try.ofFailable(() -> process(foo)));
}

is there an example/support for two async calls? such as

List<CompletableFuture<Try<Foo>>> requests1 = [...]
List<CompletableFuture<Try<Bar>>> requests2 = [...]
// requests1.size(), requests2.size() are the same value
List<CompletableFuture<Try<Baz>>> results = new ArrayList<>();
for (int i = 0; i < items1.size(); i++) {
    CompletableFuture<Try<Baz>> combined = items1.get(i).thenCombine(items2.get(i), (fooTry, barTry) -> myFunction(fooTry, barTry));
    results.add(combined);
}

List<Try<Baz>> results = results.stream().map(CompletableFuture::join).collect(Collectors.toList());
...

private Try<Baz> myFunction(Try<Foo> fooTry, Try<Bar> barTry) {
    return fooTry.flatMap(foo -> barTry.flatMap(bar -> Try.ofFailable(() -> process(foo, bar))));
}
