retry

Retry Example

This example demonstrates error handling and retry logic in workflows.

What it shows

• Retry Configuration: Different retry policies for different steps
• Error Handling: Graceful handling of failures with exponential backoff
• State Management: Preserving state across retry attempts
• Service Simulation: Realistic simulation of unreliable external services

The Workflow

1. Initialize - Welcome message
2. Call Unreliable Service - Simulates an external API with 70% failure rate
   • Retries up to 3 times with exponential backoff
   • Base delay: 500ms, max delay: 2s
3. Service Success - Confirms successful service call
4. Validate Response - Validates the service response
   • Retries up to 2 times with 200ms base delay
5. Validation Success - Confirms successful validation
6. Final Success - Completion message

Running the Example

cd examples/retry
go run main.go

Key Concepts Demonstrated

• RetryConfig: Configure different retry policies per step
• Random Failures: Realistic simulation of network/service issues
• Exponential Backoff: Intelligent retry timing to avoid overwhelming services
• Error Context: Meaningful error messages and state preservation
