> The Apex engine supports many platform level attributes like operator memory, application window count, container jvm options etc. Today these can only be set at application launch time and cannot be changed once the application is running.
> This issue is to add the ability to change the attributes dynamically even as the application is running. The mechanics of an user requesting the attribute change can be similar to how a user requests property change via the command line client.
> Since each attribute is different the actual backend implementation to affect the changes will most likely be custom handling for different attributes but during the implementation process  hopefully some common themes emerge and some amount of reuse possible.
