priority option for powershell workflow
It isn't reliable enough to know, that a workflow will start some time after it is triggered.
For example: a Workflow triggered by a webhook starts in between two or ten minutes. So one can not calculate with the result of the runbook.
Please add a option to start a workflow immidiatelly (and charge it double for example) or with extra power so we can count on it.
do you just need to know when the child job finished? if so you can use Start-AzureRMAutomationRunbook with a wait switch and then you can get the output of the job.
Powershell workflow is compiled at run time so this adds extra processing that needs to happen before the job can start in addition to the time that Azure Automation needs to start the new job.
