What would be a better way of doing the following:

listOf(
  CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>).launch { ddbTools.deleteTableInRegions(destinationTable, destinationRegions) },
  CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>).launch { jobService.deleteJobTable() },
  CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>).launch { jobService.deleteCheckpointTable() }).joinAll()

@digitalsanctum

withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
    launch { … }
    launch { … }
    launch { … }
} //No need for joinAll() thanks to structured concurrency

[digitalsanctum]

okay, great. thanks!

@louiscad follow-up question: how best to structure things around one launch depending on another?

[louiscad]

@digitalsanctum Don't launch in that case. Just execute code sequentially.

[digitalsanctum]

so just let the fact that it will block without launch dictate that it needs to finish before continuing with launches

I'm not sure I understand your sentence
