Workshop 9 Starter Code

This lesson focuses on comprehensive error handling strategies including compensation patterns and circuit breakers.

What's Provided

• workflow/ErrorHandlingWorkflow.kt - Starter interface with basic data classes
• Template for custom exception classes

What You Need To Do

Follow the instructions in ../modules/lesson_9/workshop_9.md to:

1. Create custom business exception classes
2. Implement comprehensive try-catch error handling
3. Build compensation logic (saga pattern)
4. Implement circuit breaker patterns
5. Create graceful degradation strategies

Goal

Create a workflow that:

• Handles different error types with appropriate strategies
• Implements compensation logic for partial failures
• Uses circuit breakers to prevent cascading failures
• Provides graceful degradation for non-critical services
• Includes rich error context and debugging information

Architecture Focus

This lesson emphasizes:

• Custom exception design
• Compensation patterns (saga)
• Circuit breaker implementation
• Error classification and handling strategies
• Graceful degradation patterns
