Leveraging Role Quotas to Guarantee and Limit Resource Allocations

on YouTube ↗37m

" summary

Cluster-wide role quotas (requires Mesos 0.27.0+) let operators reserve resources via a REST API and persist requests in the registry; quotas immediately reserve free capacity, can block offers (rescinds outstanding offers), and leave reserved but idle resources if tasks aren’t freed. Current limits: no preemption/oversubscription yet, quotas apply to roles only and are set from free capacity unless using the force flag, resources are non‑revocable by default; planned fixes include atomic updates, hierarchical roles and revocable‑by‑default.
