Persist the AppManager #3
Description
An AppManager object is created whenever a new Application is received by the server. The AppManager remains in memory for as long as the application is alive in the framework. During deployment, the AppManager invokes the AppDeployer interface which creates a few Map objects that is used during deployment. The same Maps are later reused whenever the Application needs to be redeployed or stopped.
It would be a useful to persist these objects in permanent storage so that the master service can reattain its previous state if it is restarted for any reason.
