Applicability: Depends on product architecture and risk

Concept

Compensation and Saga is the capability concerned with compensation and saga in the broader domain of durable automation with recoverable side effects. Its purpose is to make this concern explicit, testable, governable, and reusable across AI-powered workflows. Define the state machine, retry policy, and what side effects Compensation and Saga may create.

Recommended Practices

  • Use durable queues, idempotency keys, explicit timeouts, reconciliation, and compensation where appropriate.
  • Define an owner, API/schema contract, failure response, and acceptance criteria for compensation and saga.
  • Add automated positive, negative, boundary, and permission tests for compensation and saga; review metrics in staging and production.

Example Use Cases

  • A long-running request survives worker restarts and avoids duplicating external tickets.
  • Apply compensation and saga in a high-volume enterprise workflow while recording the user, project scope, input contract, and observable outcome.

Common Implementation Pitfalls

  • Blind retries, non-atomic state transitions, and claiming rollback for irreversible side effects.
  • No documented fallback, operational owner, or signal showing when compensation and saga is failing.
  • Testing only happy paths while ignoring missing data, revoked access, malformed outputs, and partial outages.

Production Readiness Checklist

  • An accountable owner and technical contract for compensation and saga are documented.
  • At least one successful and one failing end-to-end scenario is reproducible.
  • Access controls, retention, and audit requirements are verified where relevant.
  • Release monitoring includes a measurable success or failure signal for this capability.

Design Questions

  1. What concrete risk or business requirement requires Compensation and Saga?
  2. What happens when it is unavailable, wrong, stale, or slow?
  3. How is its success evaluated against a trusted reference or observed outcome?
  4. Who can change its configuration, and how are changes released and rolled back?
