workflow-orchestration-patterns

Design a durable workflow by leveraging Temporal for automatic state preservation, deterministic execution, and compensation patterns like Saga to coordinate multi-step order processing across microservices with reliable recovery.

The Saga pattern in workflow orchestration handles multi-step business processes by defining compensation logic for each step. Use it when coordinating transactions across microservices that require reliable rollback mechanisms upon partial failures.

Ensure determinism by keeping workflow logic free of non-deterministic operations, and guarantee idempotent activities by designing them to safely handle duplicate executions during automatic retries and state recovery.

Yes, you can use fan-out fan-in parallel execution for microservice orchestration. This workflow pattern distributes concurrent tasks across multiple services and aggregates results, optimizing throughput for distributed processing.

Handle retries and heartbeats for long-running tasks by configuring robust retry strategies and implementing heartbeat mechanisms. This ensures the orchestration engine tracks activity progress and recovers reliably from transient failures.

Choose entity-centric workflows, utilizing an actor model approach, when you need to encapsulate business logic and state around specific domain entities. This pattern provides isolated state management for durable, long-running processes.
