Multithreading – waiting for any given future in scala?
•
Java
Suppose I need to perform some parallel tasks in scala Each task performs some blocking calls (for example, process. Waitfor) Now I want to wait until any task is completed
As far as I know, I should use Scala future to wrap tasks Is there any API in scala waiting for any given futures to end?
Solution
There are built-in ways to do this:
Future.firstCompletedOf(yourFutures)
from the doc：
Please note that this does not interrupt all other futures, so you can cancel them yourself if necessary
