Launch, Join, And Hundreds of Thousands of Jobs

In the previous post I mentioned that coroutines were like lightweight threads, but lets get an idea of how many different concurrent jobs can coroutines handle.

launch

We start a coroutine with the launch lambda function. Here’s a simple example:

println("Start")

// Start a coroutine
GlobalScope.launch {
    delay(1000)
    val x = 2*6
    println(x)
}

Thread.sleep(2000) // wait for 2 seconds
println("Stop")

join
