Comment 1 for bug 1572865

Every update needs to be done with a call then push information to the DB and then the node that did the operation needs to cast that there was a change. Other nodes need to check the DB for changes periodically. Ownership can be done in the DB. There are currently existing mechanisms for knowing if an instance of a service is up or not. Operation Engine instances need to make sure to take ownership of disowned operation (or a scheduler needs to do this).
