With new SC, is there any changes in withContext vs async policy or it is ok to continue using withContext? CoroutineScope sample uses async, not `withContext`: https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.experimental/-coroutine-scope/index.html

I think withContext is still more idiomatic and optimal solution

[thevery]

It is not quite clear how withContext is connected with parent scope - async and launch are directly tied to scope but withContext is not

[kingsley]

I believe withContext is also very much a member of the scope. And very much like coroutineScope, it suspends until it’s execution is complete, which as Andrey said, it more optimal than calling eager async {}.await() in the same scope

[gildor]

withContext is also coroutine scope and also tied to parent scope

You should use async only when you need parallelism.
