Currently Mesos supports the ability to reserve resources (for a given role) on a per-slave basis, as introduced in
MESOS-505. This allows you to almost statically partition off a set of resources on a set of machines, to guarantee certain types of frameworks get some resources.
This is very useful, though it is also very useful to be able to control these reservations through the master (instead of per-slave) for when I don't care which nodes I get on, as long as I get X cpu and Y RAM, or Z sets of (X,Y).
I'm not sure what structure this could take, but apparently it has already been discussed. Would this be a CLI flag? Could there be a (authenticated) web interface to control these reservations?
