Why

• Local/dev runs shouldn’t spawn extra workers.
• Teams may want a global concurrency cap.
• Individual DAGs sometimes need dedicated queues.

What

1. Global on/off switch

   • queues.enabled in dagu.yaml (default true)
   • Env override: DAGU_QUEUE_ENABLED=false

2. Global queue settings

   • queues.config[].name
   • queues.config[].maxActiveRuns (immutable per DAG)
     • This value cannot be overridden by individual DAGs when it's specified in global queue settings

3. Per‑DAG queue name

   • YAML field queue: <name>

Config example

queues:
  enabled: true
  config:
    - name: globalQueue
      maxActiveRuns: 5

DAG example

queue: differentQueue
