## About

# AgentDB Advanced Features

## What This Skill Does

Covers advanced AgentDB capabilities for distributed systems, multi-database coordination, custom distance metrics, hybrid search (vector + metadata), QUIC synchronization, and production deployment patterns. Enables building sophisticated AI systems with sub-millisecond cross-node communication and advanced search capabilities.

**Performance**:  setTimeout(resolve, 100));
      return safeRetrieve(queryEmbedding, options);
    }
    throw error;
  }
}
```

### Monitoring and Logging

```typescript
// Performance monitoring
const startTime = Date.now();
const result = await adapter.retrieveWithReasoning(queryEmbedding, { k: 10 });
const latency = Date.now() - startTime;

if (latency > 100) {
  console.warn('Slow query detected:', latency, 'ms');
}

// Log statistics
const stats = await adapter.getStats();
console.log('Database Stats:', {
  totalPatterns: stats.totalPatterns,
  dbSize: stats.dbSize,
  cacheHitRate: stats.cacheHitRate,
  avgSearchLatency: stats.avgSearchLatency,
});
```

## CLI Advanced Operations

### Database Import/Export

```bash
# Export with compression
npx agentdb@latest export ./vectors.db ./backup.json.gz --compress

# Import from backup
npx agentdb@latest import ./backup.json.gz --decompress

# Merge databases
npx agentdb@latest merge ./db1.sqlite ./db2.sqlite ./merged.sqlite
```

### Database Optimization

```bash
# Vacuum database (reclaim space)
sqlite3 .agentdb/vectors.db "VACUUM;"

# Analyze for query optimization
sqlite3 .agentdb/vectors.db "ANALYZE;"

# Rebuild indices
npx agentdb@latest reindex ./vectors.db
```

---

## Environment Variables

```bash
# AgentDB configuration
AGENTDB_PATH=.agentdb/reasoningbank.db
AGENTDB_ENABLED=true

# Performance tuning
AGENTDB_QUANTIZATION=binary     # binary|scalar|product|none
AGENTDB_CACHE_SIZE=2000
AGENTDB_HNSW_M=16
AGENTDB_HNSW_EF=100

# Learning plugins
AGENTDB_LEARNING=true

# Reasoning agents
AGENTDB_REASONING=true

# QUIC synchronization
AGENTDB_QUIC_SYNC=true
AGENTDB_QUIC_PORT=4433
AGENTDB_QUIC_PEERS=host1:4433,host2:4433
```

---

## Troubleshooting

### Issue: QUIC sync not working

```bash
# Check firewall allows UDP port 4433
sudo ufw allow 4433/udp

# Verify peers are reachable
ping host1

# Check QUIC logs
DEBUG=agentdb:quic node server.js
```

### Issue: Hybrid search returns no results

```typescript
// Relax filters
const result = await adapter.retrieveWithReasoning(queryEmbedding, {
  k: 100,  // Increase k
  filters: {
    // Remove or relax filters
  },
});
```

### Issue: Memory consolidation too aggressive

```typescript
// Disable automatic optimization
const result = await adapter.retrieveWithReasoning(queryEmbedding, {
  optimizeMemory: false,  // Disable auto-consolidation
  k: 10,
});
```
