[Marko Mitic]

Depends on what you need. #1 could have better performance if that's critical, otherwise #2 looks better

[Marko Mitic]

If you'd need to wait on writes to be completed to do some other work, you could just wrap single launch into a coroutineScope { } and make doSomething suspending Had a brain fart here, coroutineScope { } would be more useful for #1

[Marko Mitic]

Also, try avoiding GlobalScope

[Marko Mitic]

I usually write it like this

suspend fun doSomething() = withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
    writeIntoTable1()
    writeIntoTable2()
    writeIntoTable3()
}

[gildor]

withContext(<http://Dispatchers.IO|Dispatchers.IO>) is not needed if writeIntoTableN is suspend function
