Questions about Aurora scheduling policy

[Riccardo Poggi]

Hello,

In order to introduce Aurora into our distributed system we would like 
to have it slowly, and hopefully transparently, replace what is 
currently the process manger component. To do that it would have to 
programmatically interface with other parts of the system that are, at 
the moment, taking care of what it could be considered the "active" 
orchestration.

I've tried Aurora and looked at the docs, but I'm still left with some 
open questions:

1. Would it possible to subscribe to state change for a given job/task 
and receive notifications?

2. Would it possible to set a Pending time-out for tasks that take too 
long to be Assigned?

3. Would it possible to have Aurora handle tasks with no resource 
constraints?


Thanks,
  Riccardo
