workflow-orchestration-patterns

The saga pattern implements distributed transactions with compensation logic for rollback capabilities. You need it when orchestrating multi-step processes like e-commerce fulfillment where failures require automatic state recovery and rollback.

Design durable workflows with Temporal by separating workflows and activities, enforcing determinism constraints, and leveraging automatic state persistence. This ensures long-running processes recover automatically from failures without external state management.

Separate workflows and activities by defining workflows as deterministic orchestration logic and activities as side-effectful operations interacting with external systems. This ensures reliable state persistence and automatic failure recovery in microservice orchestration.

Yes, you can model long-lived entities as stateful workflows for consistent lifecycle management. This approach provides durable state persistence and automatic failure recovery for long-running distributed system processes.

Determinism constraints require workflow code to produce identical outputs for identical inputs across replays. This means avoiding non-deterministic operations inside workflows and delegating external interactions to activities to maintain automatic state persistence.

Implement fan-out fan-in patterns by orchestrating multiple tasks concurrently within your workflow to achieve parallel execution. This allows distributed systems to handle concurrent operations while maintaining automatic state persistence and failure recovery.
