Hi all,
I try to implement an async request to a ktor-Server which shall respond directly and then start the async task.
It is possible to do it like:

put<MyRoute> {
        call.respond(HttpStatusCode.OK)
        MyService.runTask()
    }

This returns the response directly and the synchronous task seems to run until the end.
Does every call already run in a separated thread or do I have to start a new thread for the runTask()?

You have a separate coroutine running for every request

[cy]

But I’d recommend to launch a new for background tasks

[Philipp Karlsson]

okay, so it would work but it's not the way I should use it, right?

[cy]

right, because it is tied to the request and it will not complete until the coroutine is running

[cy]

could potentially lead to some strange consequences

[cy]

don’t think it will break anything unless you are doing something blocking

[cy]

so to be sure, I would run a separate coroutine

[cy]

notice the difference: coroutine vs thread

Okay, thank you very much. 👍
