Orchestration Patterns
Parallel Execution with Sync Points
Execute multiple operations simultaneously and synchronize at defined points.

- Aggregate data from multiple APIs
- Send notifications to multiple channels
- Process data through multiple transformations
Saga Pattern (Distributed Transactions)
Manage complex transactions across multiple services with compensation logic.

Event-Driven Choreography
React to events from multiple sources with decoupled processing.

Long-Running Workflows
Handle workflows that span minutes, hours, or even days.
Capabilities:
- State Persistence: Workflow state saved to durable storage
- Resume on Restart: Automatic recovery after system restart
- Timers: Wait for specific times or durations
- Human Tasks: Pause for manual approval
- Checkpoints: Save progress at critical points
Day 1: Order Received
│
▼
Day 1: Payment Processing ──▶ Wait for payment confirmation
│
▼
Day 2: Fulfillment ──▶ Wait for warehouse confirmation
│
▼
Day 3: Shipping ──▶ Wait for delivery

Day 5: Follow-up SurveySub-workflow Composition
Build complex workflows from reusable components.

Error Handling Strategies
Retry with Exponential Backoff
Attempt 1: Immediate
Attempt 2: Wait 1 second
Attempt 3: Wait 2 seconds
Attempt 4: Wait 4 seconds
Attempt 5: Wait 8 seconds
→ Max attempts reached → Fallback or AlertCircuit Breaker
Prevent cascade failures when downstream services are unhealthy.
States:
- Closed: Normal operation, requests pass through
- Open: Requests fail fast, no calls to unhealthy service
- Half-Open: Test if service recovered
Dead Letter Queue
Capture failed messages for manual review or reprocessing.
Normal Queue ──▶ Processing ──▶ Success
│
▼ (Failure after retries)
Dead Letter Queue

Manual Review / ReprocessScaling Patterns
Horizontal Scaling
Distribute workload across multiple workers.
- Queue-based distribution: Workers pull from shared queue
- Partition-based: Each worker handles specific data subset
- Load balancing: Round-robin or least-connections
Rate Limiting & Throttling
Control execution rate to prevent overwhelming downstream systems.
{
"rateLimit": {
"requests": 100,
"period": "1 minute",
"strategy": "sliding_window"
}
}Batching
Process multiple items together for efficiency.
Items 1-100 ──▶ Batch Process ──▶ Bulk Insert
Items 101-200 ──▶ Batch Process ──▶ Bulk Insert

- Start Simple: Begin with linear workflows
- Add Branching: Introduce conditions and parallel paths
- Handle Errors: Add retry and fallback logic
- Monitor: Set up observability and alerts
- Optimize: Profile and improve performance
