What is the rationale for choosing one over the other? Only difference I could infer after reading the documentation is that runAsync takes Runnable as an input parameter and supplyAsync takes Supplier as an input parameter. This stackoverflow post discusses the motivation behind using Supplier with supplyAsync method but it still does not answer when to prefer one over the

Would the thread be blocked till it does not get a response from the API? ( I know main thread/tomcat thread will be non-blocking, but what
What advantage is there to using Spring @Async vs. CompleteableFuture directly?
What’s the advantage of using Spring Async vs. Just returning the CompletableFuture on your own? Answer Your application is managed by the container. Since it’s discouraged to spawn Threads on you own, you can let the container inject a managed Executor.
“Double” composition with CompletableFuture
I’m trying to avoid nesting CompletableFuture when combining 2 independent ones with a BiFunction that returns a third one. Currently, using thenCombine() does not cut it: I’m basically trying to find a way that looks like haskell if there was a CompletableFuture monad: I read somewhere that join() is the flatMap of Completable future, so I think I could use
