             Summary: Allow frameworks to specify fine-grained demand to Mesos
                 Key: MESOS-8939
                 URL: https://issues.apache.org/jira/browse/MESOS-8939
             Project: Mesos
          Issue Type: Story
          Components: allocation
            Reporter: Vinod Kone


Currently, the only primitives a framework has to specify its demand to Mesos are filters, quota, reservations etc. But these are not enough (See MESOS-8935, MESOS-8966).

While optimistic offers is one way to solve the problem and is likely a better long term solution, we can make some improvements in the pessimistic allocation model we have today. One such solution is for the framework to convey its specific demand (e.g., exact resources required for all its current workloads) via a scheduler API call (e.g., `requestResources()` or `Call::Request`). Mesos allocator can then use this information to figure out the right shape of offers that are useful to a framework.

See MESOS-3765 for some additional context.
