Retryable Jobs

Spring Retry

@Service
public class PaymentJob {
    @Retryable(maxAttempts = 3, backoff = @Backoff(delay = 1000))
    public void processPayment(PaymentRequest request) {
        paymentGateway.charge(request);
    }

    @Recover
    public void recover(Exception e, PaymentRequest request) {
        log.error("Payment failed after retries", e);
        deadLetterService.send(request);
    }
}

Key Points

• Understanding Retryable Jobs is essential for production systems
• Always consider scalability and maintainability
• Test thoroughly before deploying to production
• Monitor performance and set up alerting

Common Patterns

1. Validation: Always validate input at the boundary
2. Error Handling: Use structured error responses
3. Logging: Log key events for debugging
4. Testing: Unit, integration, and load tests
5. Documentation: Keep docs updated with code changes

Key Principles

1. Follow SOLID principles
2. Write clean, readable code
3. Test thoroughly
4. Document decisions
5. Monitor in production

Implementation

• Start simple, refactor as needed
• Use established patterns
• Consider trade-offs
• Review with peers

Continuous Improvement

• Learn from incidents
• Update documentation
• Share knowledge
• Mentor others
