You can use the following pattern:

  1. Map your list/array to async jobs
  2. Map list of async jobs to their result

In code, it'd look like this

myData.map { data ->
    async {
        callToServer(data)
    }
}.map {
    it.await()
}

This would run each callToServer in separate job concurrently.
