This is in development and will be done soon, for full sync and imcrementalincremental
Provisioning to other systems (e.g. Box, Azure, Atlassian, etc)
...
Then that interface can be hooked up to a change log consumer and run in grouper, and the All Daemons Screen can give end to end information on if provisioning is happening. We can make provisioning specific screen screens to do this too, and provision a group, or kick off a full sync, and see the progress etc. The diagnostics monitoring can tell you end to end provisioning is happening. One place to look in logs, etc. And those logs can be in the Grouper UI. Calls direct to the database are faster than calls that go through the WS.
...
Or, a lambda (or some other runtime, or service or whatever) can be setup with grouperClient, the jar for this provisioner, and dependent jars. The grouper ESB can send events to SQS FIFO (or rabbitmq or whatever), and those events can run grouperClient code to see if should provision, check the remote info, and issue the same calls as in change log consumer. The Grouper UI would know messages are sent, but doesnt know if the destination is up to date, if messages are out of the queue, etc. You would need separate monitoring to know that messages are read and processed correctly, and you would need to look in separate logs about errors. Calls to Grouper WS can get Grouper data.
Shadow objects
MidPoint has "shadow objects" or state about the target in provisioning, inside of grouper. This makes things a lot easier as far as troubleshooting. We can hold provisioning state separate from the objects themselves so we know things about the provisioned objects even if the group or membership is deleted is grouper. Troubleshooting will be drastically improved.
Conclusion
I dont know why you would use messaging (option 2) for grouper built in supported provisioners, since you lose a lot and dont gain anything I think. If you have your own custom provisioners (could be written in non-java) and like to run from messages then knock yourself out.
