AsSystem

AsSystem<TGrant>(options): DualMethodDecorator

Defined in: packages/pipeline-job-context/src/decorators/as-system.decorator.ts:44

Runs system-started work, such as a cron job, once per configured tenant. Each run has its own tenant, a new correlation id, and the declared service principal and grants, bound through the registered IJobPrincipal. Grants come only from this declaration, never from data.

Tenants run one after another. A failing tenant does not stop the others; the method then rejects with an AggregateError of the failures. Its return values are discarded. Place it under the scheduling decorator.

    await purgeExpiredSessions();
  }
}
