How does Rails handle large-scale background workflow choreography using event-driven sagas?

Rails implements saga choreography by chaining distributed events across services with compensating actions.

Saga choreography is a decentralized workflow where each service reacts to events and emits subsequent events. Rails participates by publishing and consuming domain events via background jobs or message brokers. Each step is independently committed, and failures trigger compensating transactions. This model avoids centralized orchestration but requires careful event design and idempotency.
