Workshop 8 Starter Code

This lesson focuses on building resilient workflows with sophisticated retry and timeout strategies.

What's Provided

• workflow/ResilientWorkflow.kt - Starter interface with basic data classes
• Template for different retry strategies

What You Need To Do

Follow the instructions in ../modules/lesson_8/workshop_8.md to:

1. Implement the ResilientWorkflow interface and implementation
2. Configure different retry policies for different activity types:
   • Aggressive retries for quick validation
   • Conservative retries for external APIs
   • Moderate retries for database operations
3. Implement proper timeout strategies
4. Handle different failure types appropriately

Goal

Create a workflow that:

• Demonstrates different retry strategies for different operation types
• Uses exponential backoff and jitter appropriately
• Handles retriable vs non-retriable failures correctly
• Implements activity heartbeats for long-running operations
• Provides comprehensive failure information

Architecture Focus

This lesson emphasizes:

• Retry policy configuration
• Timeout strategy selection
• Failure classification (retriable vs non-retriable)
• Activity heartbeat patterns
• Observability and retry metrics
