Task #2: Hangfire Background Jobs (COMPLETE)

Configuration: src/InsightLearn.Application/Program.cs

Features Implemented:

  1. SQL Server Storage:

    • Persistent job queue with dedicated HangfireSchema
    • Auto-creates database tables on first run
    • Connection pooling (5-100 connections)
  2. Worker Configuration:

    • Workers: 2x CPU cores (e.g., 16 workers on 8-core CPU)
    • Priority queues: critical, default, low
    • Polling interval: 15 seconds for scheduled jobs
  3. Dashboard:

    • URL: /hangfire (Admin access only)
    • Real-time job monitoring
    • Stats refresh: every 2 seconds
    • Security: Connection string hidden
  4. Background Jobs Registered:

    • TranscriptGenerationJob - Whisper API integration (3 retries: 1m, 5m, 15m)
    • AITakeawayGenerationJob - Ollama AI integration (3 retries: 30s, 2m, 5m)

Automatic Retry Logic:

  • Transcript failures: Retry after 1 min → 5 min → 15 min
  • AI takeaway failures: Retry after 30s → 2 min → 5 min

Task #3: Whisper ASR Service Configuration (COMPLETE)

Configuration: src/InsightLearn.Application/appsettings.json

{
  "Whisper": {
    "BaseUrl": "http://whisper-service:9000",
    "Timeout": 600,
    "Comment": "Self-hosted Whisper API for video transcription"
  }
}

Documentation Created:

  • docs/WHISPER-ASR-SETUP.md - Complete setup guide (150+ lines)
    • 3 deployment options (Docker Compose, Kubernetes, OpenAI Cloud)
    • Performance tuning (model selection, hardware requirements)
    • API documentation
    • Troubleshooting guide
    • Cost analysis (self-hosted vs cloud)

Kubernetes Deployment:

  • k8s/19-whisper-deployment.yaml - Production-ready manifest
    • Uses onerahmet/openai-whisper-asr-webservice:latest image
    • Model: large-v3 (99% accuracy, SOTA)
    • Engine: faster_whisper (4x faster inference)
    • Resources: 4-8GB RAM, optional GPU support
    • Health checks: liveness + readiness probes
    • PVC: 10GB for model cache

Deployment Commands:

# Deploy Whisper service
kubectl apply -f k8s/19-whisper-deployment.yaml

# Wait for pod ready (5-10 minutes for model download)
kubectl wait --for=condition=ready pod -l app=whisper -n insightlearn --timeout=600s

# Test the service
kubectl port-forward -n insightlearn svc/whisper-service 9000:9000
curl -X POST http://localhost:9000/asr -H "Content-Type: application/json" \
  -d '{"audio_url": "https://example.com/video.mp4", "language": "en", "task": "transcribe"}'

Task #4: Build Warnings Fixed (COMPLETE)

Issue: AspNetCore.HealthChecks.Elasticsearch version mismatch (8.2.1 → 9.0.0)

Fix: Updated package reference in InsightLearn.Application.csproj

<PackageReference Include="AspNetCore.HealthChecks.Elasticsearch" Version="9.0.0" />

🚀 Next Steps (Phase 4)

The following tasks remain for Phase 4 (Frontend Implementation):

1. Implement Frontend Components (Week 8-10)

4 Blazor WASM Components to implement:

  • StudentNotesPanel.razor - Markdown note editor with bookmark/share
  • VideoTranscriptViewer.razor - Searchable transcript with timestamp navigation
  • AITakeawaysPanel.razor - Key concepts display with feedback
  • VideoProgressIndicator.razor - Progress bar with bookmarks overlay

6 Frontend API Client Services to implement:

  • IStudentNoteClientService + implementation
  • IVideoTranscriptClientService + implementation
  • IAITakeawayClientService + implementation
  • IVideoBookmarkClientService + implementation
  • IVideoProgressClientService + implementation
  • IAIConversationClientService + implementation (requires SignalR)

Shared Styles:

  • learning-space.css - Responsive design with animations

Estimated Work: 3-4 weeks (8-10 hours/week)

2. SignalR Real-Time Features (Phase 4.5)

Real-Time AI Chat (4 endpoints currently at 501):

  • ⏳ Implement SignalR hub for streaming AI responses
  • ⏳ Update AI Chat endpoints to use SignalR instead of REST
  • ⏳ Add WebSocket support in frontend

Estimated Work: 1 week

3. Integration Testing (Week 11)

  • ⏳ E2E user journeys (watch video → take notes → ask AI → complete lesson)
  • ⏳ Load testing (100 concurrent users, 500 AI messages/min)
  • ⏳ Security testing (authorization, SQL injection, XSS)
  • ⏳ Accessibility testing (WCAG 2.1 AA compliance)

4. Production Deployment (Week 12)

  • ⏳ Deploy Whisper service to production Kubernetes cluster
  • ⏳ Update Grafana dashboards (transcript metrics, AI response times)
  • ⏳ Update Prometheus alerts (job failures, slow transcription)
  • ⏳ Final user acceptance testing

🧪 Testing Guide

Test REST API Endpoints via Swagger

  1. Start API:
cd src/InsightLearn.Application
dotnet run
  1. Access Swagger UI:
http://localhost:5000/swagger
  1. Test Endpoints:

    • Video Transcripts: Try GET /api/transcripts/{lessonId}/status
    • Student Notes: Try GET /api/student-notes/lesson/{lessonId}
    • AI Takeaways: Try GET /api/takeaways/{lessonId}
  2. Test Hangfire Dashboard:

http://localhost:5000/hangfire

(Requires Admin role - use JWT token from /api/auth/login)

Test Whisper Service (After Deployment)

# Port-forward Whisper service
kubectl port-forward -n insightlearn svc/whisper-service 9000:9000

# Test transcription
curl -X POST http://localhost:9000/asr \
  -H "Content-Type: application/json" \
  -d '{
    "audio_url": "https://www.kozco.com/tech/piano2-CoolEdit.mp3",
    "language": "en",
    "task": "transcribe",
    "word_timestamps": true
  }'
