Execution Backends

The backend interface behind Orchestration’s interpret and generate modes.

Execution backends and the default profile

The orchestrator is a backend interface, not one engine. Two axes swap independently and a component definition does not change across them: the trigger/scheduler host (when and what to invoke) and the execution engine (how a run executes).

• General-consumption default. Plain CI (generated) for the trigger and runner, the local executor for one-shot deploys, native scheduling. Zero exotic dependencies — this is what keeps the model broadly adoptable rather than “requires our stack.”
• Cloud/k8s-native. Lean on what the platform already reconciles and schedules — CronJob/Jobs/Argo on k8s, native schedulers and CloudFormation deploy on AWS.
• Opt-in advanced backends. Temporal as the durable execution engine for gated or crash-resumable components; Dagster or Airflow as a team-owned trigger host that invokes chant run. Chosen when a team needs or owns them, never baseline.

Keep logic out of the trigger

When a team-owned scheduler (Dagster, Airflow) hosts the trigger, keep it a thin caller of the component. The moment a trigger op starts doing publish/apply/rollback itself, the logic splits across two systems and sprawl returns in a new tool.
