# 7. Optional: Run OrKa UI for visual workflow monitoring
docker pull marcosomma/orka-ui:latest
docker run -it -p 80:80 --name orka-ui marcosomma/orka-ui:latest
# Then open http://localhost in your browser

This creates an intelligent Q&A system that:

• Classifies your query type
• Searches existing knowledge with 100x faster vector search
• Gets fresh information from the web
• Combines both sources into a comprehensive answer
• Stores the interaction for future reference

🧠 Hands-On: Build Your First AI Memory System

Let's build a conversational AI that remembers and learns from interactions:

Step 1: Create the Workflow

# conversational-ai.yml
orchestrator:
  id: conversational-ai
  strategy: sequential
  memory_config:
    decay:
      enabled: true
      default_short_term_hours: 2    # Conversations fade after 2 hours
      default_long_term_hours: 168   # Important info lasts 1 week
  agents:
    - conversation_context
    - interaction_classifier  
    - response_generator
    - memory_storage

agents:
  # Retrieve relevant conversation history
  - id: conversation_context
    type: memory-reader
    namespace: user_conversations
    params:
      limit: 5
      enable_context_search: true
      context_weight: 0.4
      temporal_weight: 0.3
      enable_temporal_ranking: true
    prompt: "Find relevant conversation history for: {{ input }}"

  # Understand the interaction type
  - id: interaction_classifier
    type: openai-classification
    prompt: |
      Based on history: {{ previous_outputs.conversation_context }}
      Current input: {{ input }}
      
      Classify this interaction:
    options: [question, followup, correction, new_topic, feedback]

  # Generate contextually aware response
  - id: response_generator
    type: openai-answer
    prompt: |
      Conversation history: {{ previous_outputs.conversation_context }}
      Interaction type: {{ previous_outputs.interaction_classifier }}
      Current input: {{ input }}
      
      Generate a response that acknowledges the conversation history
      and maintains continuity.

  # Store the interaction with intelligent classification
  - id: memory_storage
    type: memory-writer
    namespace: user_conversations
    params:
      vector: true  # Enable semantic search
      metadata:
        interaction_type: "{{ previous_outputs.interaction_classifier }}"
        has_history: "{{ previous_outputs.conversation_context | length > 0 }}"
        response_quality: "pending_feedback"
        timestamp: "{{ now() }}"
    # memory_type automatically classified based on importance
    prompt: |
      User: {{ input }}
      Type: {{ previous_outputs.interaction_classifier }}
      Assistant: {{ previous_outputs.response_generator }}

Step 2: Run and Monitor

# Start the conversation
python -m orka.orka_cli ./conversational-ai.yml "Hello, I'm working on a machine learning project"

# Continue the conversation (it will remember context)
python -m orka.orka_cli ./conversational-ai.yml "What algorithms would you recommend for image classification?"

# Monitor memory performance in real-time
python -m orka.orka_cli memory watch

You'll see a professional dashboard like this:

┌─────────────────────────────────────────────────────────────┐
│ OrKa Memory Dashboard - 14:23:45 | Backend: redisstack     │
├─────────────────────────────────────────────────────────────┤
│ 🔧 Backend: redisstack (HNSW)  ⚡ Decay: ✅ Enabled        │
│ 📊 Memories: 1,247            📝 Active: 1,224             │
│ 🚀 HNSW Performance: 1,203     Avg: 2.1ms | Hybrid: 856   │
│ 🧠 Memory Types: Short: 423    💾 Long: 801 | 🔥 Recent   │
└─────────────────────────────────────────────────────────────┘

Step 3: Verify Memory Learning

# Check what the AI remembers about you
python -m orka.orka_cli memory stats

# Search specific memories
redis-cli FT.SEARCH orka:mem:idx "@namespace:user_conversations machine learning" LIMIT 0 5

🐛 Troubleshooting

Common Issues & Quick Fixes

Issue	Quick Fix
"unknown command 'FT.CREATE'"	You're using basic Redis. Install RedisStack: docker run -d -p 6379:6379 redis/redis-stack:latest
"Cannot connect to Redis"	Check Redis is running: redis-cli ping
Memory search returns no results	Check vector indexing: redis-cli FT._LIST
Slow performance	Verify RedisStack HNSW: orka memory configure
Out of memory errors	Run cleanup: orka memory cleanup

Performance Optimization

# Check current performance
orka memory watch

# Optimize HNSW index
redis-cli FT.CONFIG SET FORK_GC_CLEAN_THRESHOLD 100

# Monitor Redis memory usage
redis-cli INFO memory

📊 Performance Benchmarks

Metric	Basic Redis	RedisStack HNSW	Improvement
Vector Search	50-200ms	0.5-5ms	100x faster
Memory Usage	100% baseline	40%	60% reduction
Throughput	1,000/sec	50,000/sec	50x higher
Concurrent Searches	10-50	1,000+	20x more
