Marathon and Jobs - Today and Tomorrow
summary
Marathon evolution focuses on concrete features and tradeoffs: added local persistent volumes and external storage via RexRay; introduced the Universal Container Runtime to run Docker images without a Docker daemon; added GPU and CNI support, pods (task groups), Mesos-agent health checks, and a secrets API that mounts secrets as files. Debugging adds a v2 queue endpoint and CI runs ~40 nightly Mesos clusters; a 2,000-app health‑check bottleneck drove the agent‑side checks. Roadmap covers CSI, fault‑domains, multi‑role scheduling and merging job lifecycle with Metronome; many features are implemented or actively prototyped.
