Workflow Orchestration Patterns
Design durable workflows with Temporal for distributed systems.
A complete playbook for building durable, fault-tolerant workflows on Temporal, drawing the hard line between orchestration logic (deterministic workflows) and external side effects (idempotent activities). It turns multi-step processes that span services, databases and APIs into systems that survive crashes and resume exactly where they left off. The difference between a pipeline that loses orders on a network blip and one that runs reliably for years.

Does this step touch an external system? That single question splits every Temporal design here: side effects become activities, coordination stays deterministic, and each step registers its undo before it ever runs.
- Splits every step through one question first: does it touch an external system? If yes it becomes an activity (API call, DB write, email); if it is decision or coordination logic it stays in the workflow, which must remain deterministic.
- Enforces determinism inside the workflow: no datetime.now(), no random(), no threading, no direct I/O; time and randomness come only from workflow.now() and workflow.random(), and every side effect is pushed into an activity.
- Wires the saga: for each step it registers the compensating action before executing (reserve_inventory pairs with release_inventory, charge_payment with refund), and on failure runs all registered compensations in reverse LIFO order.
- Hardens activities for retry reality: every activity gets a timeout, a retry policy with backoff and max attempts, idempotency via dedup keys or upserts because Temporal will re-run them, and non-retryable errors (validation, not-found) are classified so they fail fast.
- Keeps long work alive and bounded: long activities heartbeat with progress so stalls are detected, and long workflows call ContinueAsNew in batches to cap event-history size.
- Scales by decomposition, never by inflating one workflow: a million tasks become roughly 1000 child workflows of 1000 tasks each, with critical and batch traffic isolated on separate task queues (bulkhead) so one overloaded queue cannot starve payments.

-
Is this Temporal-specific, or does it apply to any workflow engine?
It is written for Temporal: the determinism constraint checklist, bounded child workflows, versioning strategies and activity heartbeats all assume Temporal's execution model. The saga and idempotency thinking transfers elsewhere, but the code-level guidance is Temporal.
-
Why can't I orchestrate this myself with queues, cron jobs and retries?
You can, until a crash hits mid-process. Hand-rolled orchestration loses state and breeds silent replay corruption and duplicate-execution bugs; this playbook's hard line between deterministic workflows and idempotent activities, plus compensation registered before execution and run in reverse LIFO order, is exactly the discipline that prevents those failure modes.
-
Does it also cover the TDD task workflow with checkpoints and commits?
No, that is the separate workflow-patterns skill. This one is about durable distributed-system orchestration: sagas, retry policies, fan-out/fan-in, entity lifecycles and human-in-the-loop approvals that survive crashes and resume exactly where they stopped.
