Dispatcher for Default Worker Pool

[CharlieTap]

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.
