here's a #java style question.

// completed with null if not found

CompletableFuture findObject();

// completed exceptionally if not found

CompletableFuture findObject();

// empty Optional if not found

CompletableFuture<Optional> findObject();

they'd all work so this is about style. which would be preferred?

the middle one is odd-one-out as it semantically says it's an error if the object can't be found rather than that being allowable.

Toot

i would tend to return the Optional if it was direct and not in a Future. But in the context of returning a Future it feels excessively clunky maybe?
