I have a question on coroutines. I want to launch two coroutines asynchronously and wait on whichever completes first, is this possible? The context here is that two separate server calls can be made independently and if either returns an error I want to cancel the remaining coroutine and error out.

I think this is possible with

select

Thanks, I looked into select. I think I may have to use something like runBlocking instead because if the first thread succeeds I want to get the response from the second thread. I suppose I could always cancel the second thread of the first thread fails.

This is what structured concurrency does. Wrap the two in a

coroutineScope

and if you launch the two jobs using

async

, one of them failing automatically cancels the other

This is exactly what I was looking for, thanks!

await just suspends until the specific Deferred is completed (regardless if the other one completes first or not). It doesn't necessarily mean the one you awaited first will finish first
