                 → FAILED
                 → CANCELLED

Status Entity

@Entity
public class JobExecution {
    @Id @GeneratedValue
    private Long id;
    private String jobType;
    private String status;  // PENDING, RUNNING, COMPLETED, FAILED
    private String error;
    private LocalDateTime startedAt;
    private LocalDateTime completedAt;
}

Key Points

• Understanding Job Status Tracking 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
