Thank you Basant for making this. I would like to add one more point as completable future by default uses forkjoin pool, this pool has core pool size, if the application is IO intensive it is good to use overloaded constructor (thread pool) to achieve max throughput.

Hi Java Techie, You gave the example of runAsync(). In that you called get(). My question is that is correct that the main thread calls get() method of completable future instance, because in that case only CompletableFuture will get chance to complete processing. CompletableFuture has Daemon threads if main thread dies then daemon will be automatically died. If we did not use get method rather we use callback then we have to make the main thread sleep for seconds so that CompletableFuture and its callback will get chance to complete process otherwise daemon threads of CompletableFuture, will die along with main thread of JVM.

Thank you for the video! Is it possible to use this approach assuming the following scenario? We have a method in the service layer that is calling inside 6 external services using feign client. We would like to call them in parallel to reduce the execution time. Keep in mind that each of these API calls is also validation the data they receive. If all the checks of every external API call is ok, then we are fine. In case at least one of the API results does not satisfy our conditions, we have to throw an exception. Can we use this approach or there is another way to do it? Thank you in advance for your time!
