[jira] [Created] (MESOS-8068) Non-revocable bursting over quota guarantees via limits.

Benjamin Mahler created MESOS-8068:
--------------------------------------

             Summary: Non-revocable bursting over quota guarantees via limits.
                 Key: MESOS-8068
                 URL: https://issues.apache.org/jira/browse/MESOS-8068
             Project: Mesos
          Issue Type: Epic
          Components: allocation
            Reporter: Benjamin Mahler


Prior to introducing a revocable tier of allocation (see MESOS-4441), there is a notion of whether a role can burst over its quota guarantee.

We currently apply implicit limits in the following way:

No quota guarantee set: (guarantee 0, no limit)
Quota guarantee set: (guarantee G, limit G)

That is, we only allow support burst-only without guarantee and guarantee-only without burst. We do not support bursting over some non-zero guarantee: (guarantee G, limit L >= G).

The idea here is that we should make these implicit limits explicit to clarify for users the distinction between guarantees and limits, and to support bursting over the guarantee.
