Sargun Dhillon commented on MESOS-3826:
---------------------------------------
This requires putting the onus of tracking reserved resources on the framework
developers. If our framework requires 1000 mb per agent, across 5 agents in
order to work correctly, we have to keep track of how much our framework has
been able to successfully reserve. It'd be nice to keep these in Mesos itself,
so that Mesos can be the canonical store for information about reservations, as
opposed to having to do more accounting.

> Thanks to the resource reservation primitives, frameworks can reserve
> resources. These reservations are per role, which means multiple frameworks
> can share reservations. This can get very hairy, as multiple reservations can
> occur on each agent.
> It would be nice to be able to optionally, uniquely identify reservations by
> ID, much like persistent volumes are today. This could be done by adding a
> new protobuf field, such as Resource.ReservationInfo.id, that if set upon
> reservation time, would come back when the reservation is advertised.
