Dispatcher for Default Worker Pool
As the title mentions there is no coroutine dispatcher available for this, blocking workloads are only achievable through awaitBlocking call. The awaitBlocking call is a bit limiting in the sense that it expects a regular block of code, not a suspending block, so I can't:
awaitBlocking {
supendingFunction()
}
Ideally I could just
withContext(Dispatchers.VertxWorkerPool) {
}
Currently I just use the standard pools provided by the coroutines library to circumvent this but I don't really want to be wasting memory on the vertx worker pool if im not using it
I agree with CharlieTap because now it's hard to use third party library with coroutine support.
Look at the difference:
With awaitBlocking:
val result = awaitBlocking {
return@awaitBlocking transaction(db) {
<db working code>
}
}
With worker dispatcher, it would be like:
val result = suspendTransaction(vertxContext.workerDispatcher()) {
<db working code>
}
You can use Vert.executeBlocking
and invoke await
on the returned future.
