We need to decide how to assign unique app ids to loaded apps. App Id

Is int a requirement or an optimization?
Here are some thoughts.
Not needed in local mode.
Can we deploy the same s4r file for more than one owner or with diff
inputs?
Why not? But this also adds the concept of tenancy or ownership to S4
applications right?
If yes maybe some manifest properties should be set at deploy time. I
think this is a requirement because S4r may have different input
streams but otherwise apps can be identical.
Should the id be set by deployer tool by setting a manifest property?
Not sure the best way is to set a "manifest" property though, since this
is part of the s4r package. Rather, the platform could compute an id for
the app, and this id could stay in zookeeper, along with other runtime
parameters for the application.
We'll probably need a way to get the app id from the owner and app
characteristics (name...).
How do we configure event source? By deployer tool or post deployment.
We should have all the info before deployment so it might make sense
to do it before and wiring is done during init. (if dependencies are
not available, the app will fail to start).
Can you give more information about what you define as event source?
Thanks!
