Created simplified.go demonstrating target architecture:
internal/worker/simplified.go (109 lines)
- SimplifiedWorker struct with 6 fields vs original 27 fields
- Uses composed dependencies from previous phases:
- lifecycle.RunLoop for task lifecycle management
- executor.JobRunner for job execution
- lifecycle.HealthMonitor for health tracking
- lifecycle.MetricsRecorder for metrics
Key improvements demonstrated:
- Dependency injection via SimplifiedWorkerConfig
- Clear separation of concerns
- No direct resource access (queue, metrics, etc.)
- Each component implements a defined interface
- Easy to test with mock implementations
Note: This is a demonstration of the target architecture.
The original Worker struct remains for backward compatibility.
Migration would happen incrementally in future PRs.
