deepStart

public static java.util.concurrent.CompletableFuture<java.lang.Void> deepStart(java.util.stream.Stream<Startable> startables)

Start every Startable recursively and asynchronously and join on the result. Performance note: The method uses and returns CompletableFutures to resolve as many Startables at once as possible. This way, for the following graph: / b \ a e c / d / "a", "c" and "d" will resolve in parallel, then "b". If we would call blocking Startable.start(), "e" would wait for "b", "b" for "a", and only then "c", and then "d". But, since "c" and "d" are independent from "a", there is no point in waiting for "a" to be resolved first.

Parameters:

startables - a Stream of Startables to start and scan for transitive dependencies.

Returns:

a CompletableFuture that resolves once all Startables have started.
