I’m about to write a workflow in CRM that calls itself every day. This is a recursive workflow.
It will run on half a million entities each day and deactive the record if it was not been upodated in the past 3 days.
I’m worried about performance has anyone else done this.
You’ll want to make sure your workflow is running in non-peak hours. Assuming you have an on-premise installation you should be able to get away with that. If you’re using a hosted instance, you might be worried about one organization running the workflow while another organization is using the system. Use the timeout and maybe a custom workflow activity, if necessary, to force the start time to a certain period.
I’m assuming you’ll be as efficient as possible in figuring out which records to deactivate. (i.e. Query Expression would only bring back the records you’ll be deactivating).
The built-in infinite loop-protection offered by CRM shouldn’t kill your workflow instances. It stops after a call depth of 8, but it resets to 1 if no calls are made for an hour. So the fact that you’re doing this once a day should make you OK on the recursive workflow front.
