workflow-orchestration-patterns

Master workflow orchestration architecture with Temporal, covering fundamental design decisions, resilience patterns, and best practices for building reliable distributed systems. The Fundamental Rule (Source: temporal.io/blog/workflow-engine-principles): Characteristics: Example workflow tasks: Characteristics: Example activity tasks: Purpose : Implement distributed transactions with rollback capability Pattern (Source: temporal.io/blog/compensating-actions-part-of-a-complete-breakfast-with-sagas): Example: Payment Workflow Critical Requirements: Purpose : Long-lived workflow representing single entity instance Pattern (Source: docs.temporal.io/evaluate/use-cases-design-patterns): Example Use Cases: Benefits: Purpose : Execute multiple tasks in parallel, aggregate results Pattern: Scaling Rule (Source: temporal.io/blog/workflow-engine-principles): Purpose : Wait for external event or human approval Pattern: Use Cases: How Temporal Works (Source: docs.temporal.io/workflows): Workflows Execute as State Machines : Prohibited in Workflows (Source: docs.temporal.io/workflows): Allowed in Workflows : Challenge : Changing workflow code while old executions still running Solutions : Default Behavior : Temporal retries activities forever Configure Retry : Non-Retryable Errors : Why Critical (Source: docs.temporal.io/activities): Implementation Strategies : Purpose : Detect stalled...
