第10章 编排、调度与资源


I. 章节目的与范围

的规范:编排后端与拓扑提交、优先级与抢占、触发与依赖、重试与超时、SLA/SLO 与告警、资源画像与配额、自动扩缩与成本计量;确保与数据契约、质量门、监控与计量章一致。资源(resources)调度(scheduling)编排(orchestration)固化流水线

II. 术语与依赖


III. 字段与结构(规范性)

XI. Lint 规则(节选,规范性)

lint_rules:

- id: ORCH.ORCHESTRATOR_ALLOWED

when: "$.orchestration.orchestrator"

assert: "value in ['airflow','argo','ray','custom']"

level: error

- id: SCHED.TIMEOUT_DEFINED

when: "$.scheduling.timeout_s"

assert: "is_number(value) and value > 0"

level: error

- id: SCHED.RETRIES_VALID

when: "$.scheduling.retries"

assert: "value.max >= 0 and value.backoff in ['expo','linear']"

level: error

- id: SLA.METRICS_DEFINED

when: "$.scheduling.sla"

assert: "has_keys(latency_ms, availability, error_rate)"

level: error

- id: RES.REQUESTS_LIMITS

when: "$.resources"

assert: "has_keys(requests, limits) and requests.cpu <= limits.cpu and requests.mem_gb <= limits.mem_gb"

level: error

- id: AUTOSCALE.BOUNDS

when: "$.autoscale"

assert: "value.enabled == false or (value.policy.min_replicas >= 1 and value.policy.max_replicas >= value.policy.min_replicas)"

level: error
