# Storage Architecture (v4.0.0)
|

> **Updated for v4.0.0**: Metadata/vector separation, UUID-based sharding, lifecycle management
|

|
||||
## Storage Structure
|
||||
|
||||
### v4.0.0 Architecture: Metadata/Vector Separation
|
||||
|
||||
In v4.0.0, entities and relationships are split into **2 separate files** for optimal performance at billion-entity scale:
|
||||
|
||||
```

|
||||
│ │
|
||||
│ └── metadata/ # Relationship data (sharded)
|
||||
│ ├── 00/ ... ff/
|
||||
```
|
||||
|
||||
### Why Split Metadata and Vectors?
|
||||
|
||||
**Performance at scale:**
|
||||
- **HNSW operations**: Only load vectors (4KB) during search, not metadata (2-10KB)
|
||||
- **Filtering**: Only load metadata during filtering, not vectors
|
||||
- **Pagination**: Load metadata IDs first, fetch vectors/metadata on-demand
|
||||
- **Result**: 60-70% reduction in I/O for typical queries at million-entity scale
|
||||
|
||||
### UUID-Based Sharding (256 Shards)
|
||||
|
||||
**How it works:**
|
||||
```typescript
|
||||
const uuid = "3fa85f64-5717-4562-b3fc-2c963f66afa6"
|
||||
const shard = uuid.substring(0, 2) // "3f"
|
||||
|
||||
// Vector path: entities/nouns/vectors/3f/3fa85f64-....json
|
||||
// Metadata path: entities/nouns/metadata/3f/3fa85f64-....json
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- **Uniform distribution**: ~3,900 entities per shard (at 1M scale)
|
||||
- **Cloud storage optimization**: 200x faster than unsharded (30s → 150ms)
|
||||
- **Parallel operations**: Load 256 shards in parallel
|
||||
- **Predictable**: Deterministic shard assignment
|
||||
|
||||

### 1. Lifecycle Policies (Cloud Storage)
|
||||
|
||||
**Automatic cost optimization through tier transitions:**
|
||||
|
||||
```typescript
|
||||
// S3: Set lifecycle policy for automatic archival
|
||||
await storage.setLifecyclePolicy({
|
||||
rules: [{
|
||||
id: 'archive-old-data',
|
||||
prefix: 'entities/',
|
||||
status: 'Enabled',
|
||||
transitions: [
|
||||
{ days: 30, storageClass: 'STANDARD_IA' }, // Move to IA after 30 days
|
||||
{ days: 90, storageClass: 'GLACIER' }, // Archive after 90 days
|
||||
{ days: 365, storageClass: 'DEEP_ARCHIVE' } // Deep archive after 1 year
|
||||
]
|
||||
}]
|
||||
})
|
||||
|
||||
// GCS: Set lifecycle policy
|
||||
await storage.setLifecyclePolicy({
|
||||
rules: [{
|
||||
condition: { age: 30 },
|
||||
action: { type: 'SetStorageClass', storageClass: 'NEARLINE' }
|
||||
}, {
|
||||
condition: { age: 90 },
|
||||
action: { type: 'SetStorageClass', storageClass: 'COLDLINE' }
|
||||
}, {
|
||||
condition: { age: 365 },
|
||||
action: { type: 'SetStorageClass', storageClass: 'ARCHIVE' }
|
||||
}]
|
||||
})
|
||||
|
||||
// Azure: Set lifecycle policy
|
||||
await storage.setLifecyclePolicy({
|
||||
rules: [{
|
||||
name: 'archiveOldData',
|
||||
enabled: true,
|
||||
type: 'Lifecycle',
|
||||
definition: {
|
||||
filters: { blobTypes: ['blockBlob'] },
|
||||
actions: {
|
||||
baseBlob: {
|
||||
tierToCool: { daysAfterModificationGreaterThan: 30 },
|
||||
tierToArchive: { daysAfterModificationGreaterThan: 90 }
|
||||
}
|
||||
}
|
||||
}
|
||||
}]
|
||||
})
|
||||
```
|
||||
|
||||
**Cost Impact (500TB dataset):**
|
||||
| Storage | Before | After | Savings |
|
||||
|---------|--------|-------|---------|
|
||||
| **AWS S3** | $138,000/yr | $5,940/yr | **96%** |

|
||||
|
||||
### 2. Intelligent-Tiering (S3)
|
||||
|
||||
**Automatic optimization without retrieval fees:**
|
||||
|
||||
```typescript
|
||||
// Enable S3 Intelligent-Tiering
|
||||
await storage.enableIntelligentTiering('entities/', 'auto-optimize')
|
||||
|
||||
// Benefits:
|
||||
// - Automatic tier transitions based on access patterns
|
||||
// - No retrieval fees (unlike Glacier)
|
||||
// - Up to 95% cost savings
|
||||
// - No performance impact on frequently accessed data
|
||||
```
|
||||
|
||||
### 3. Autoclass (GCS)
|
||||
|
||||
**Google Cloud's intelligent automatic optimization:**
|
||||
|
||||
```typescript
|
||||
// Enable GCS Autoclass
|
||||
await storage.enableAutoclass({
|
||||
terminalStorageClass: 'ARCHIVE' // Optional: Set lowest tier
|
||||
})
|
||||
|
||||
// Benefits:
|
||||
// - Automatic optimization based on access patterns
|
||||
// - No data retrieval delays
|
||||
// - Transparent tier transitions
|
||||
// - Up to 94% cost savings
|
||||
```
|
||||
|
||||
### 4. Compression (FileSystem)
|
||||
|
||||
```typescript
|
||||
// Enable gzip compression for local storage
|
||||
const brain = new Brainy({
|
||||
storage: {
|
||||
type: 'filesystem',
|
||||
path: './data',
|
||||
compression: true // 60-80% space savings
|
||||
}
|
||||
})
|
||||
|
||||
// Performance impact:
|
||||
// - Write: +10-20ms per file (gzip compression)
|
||||
// - Read: +5-10ms per file (gzip decompression)
|
||||
// - Space savings: 60-80% for typical JSON data
|
||||
// - CPU overhead: Minimal (~5% CPU)
|
||||
```
|
||||
|
||||
### 5. Batch Operations
|
||||
|
||||
```typescript
|
||||
// v4.0.0: Efficient batch delete
|
||||
await storage.batchDelete([
|
||||
'entities/nouns/vectors/00/00123456-....json',
|
||||
'entities/nouns/metadata/00/00123456-....json',
|
||||
// ... up to 1000 objects
|
||||
])
|
||||
|
||||
// Benefits:
|
||||
// - S3: 1000 objects per request (vs 1 per request)
|
||||
// - GCS: 100 objects per request
|
||||
// - Azure: 256 objects per batch
|
||||
// - Automatic retry logic with exponential backoff
|
||||
// - Throttling protection
|
||||
|
||||
// Batch writes for performance
|
||||
await brain.addBatch([
|
||||
{ content: "item1", metadata: {} },
|
||||
{ content: "item2", metadata: {} },
|
||||
{ content: "item3", metadata: {} }
|
||||
])
|
||||
// Single transaction, optimized I/O
|
||||
```
|
||||
|
||||
### 6. Quota Monitoring (OPFS)
|
||||
|
||||
```typescript
|
||||
// Get quota status for browser storage
|
||||
const status = await storage.getStorageStatus()
|
||||
|
||||
console.log(status)
|
||||
// {
|
||||
// type: 'opfs',
|
||||
// available: true,
|
||||
// details: {
|
||||
// usage: 45829120, // 43.7 MB used
|
||||
// quota: 536870912, // 512 MB available
|
||||
// usagePercent: 8.5,
|
||||
// quotaExceeded: false
|
||||
// }
|
||||
// }
|
||||
|
||||
// Proactive quota management:
|
||||
// - Monitor usage before writes
|
||||
// - Warn users when approaching quota
|
||||
// - Automatically clean up old data
|
||||
```
|
||||
|
||||
### 7. Tier Management (Azure)
|
||||
|
||||
```typescript
|
||||
// Change blob tier for cost optimization
|
||||
await storage.changeBlobTier(blobPath, 'Cool') // Hot → Cool (50% savings)
|
||||
await storage.changeBlobTier(blobPath, 'Archive') // Cool → Archive (99% savings)
|
||||
|
||||
// Batch tier changes (efficient)
|
||||
await storage.batchChangeTier([blob1, blob2, blob3], 'Cool')
|
||||
|
||||
// Rehydrate from Archive when needed
|
||||
await storage.rehydrateBlob(blobPath, 'Standard') // Standard or High priority
|
||||
```

## Best Practices
|
||||
## Best Practices (v4.0.0)
|
||||
|
||||
### Choose the Right Adapter
|
||||
1. **Development**: FileSystem (local persistence)
|
||||
2. **Production Server**: FileSystem or S3
|
||||
3. **Browser Apps**: OPFS
|
||||
4. **Distributed**: S3 with caching
|
||||
1. **Development**: FileSystem with compression (local persistence, small storage footprint)
|
||||
2. **Production Server**: FileSystem with compression or cloud storage with lifecycle policies
|
||||
3. **Browser Apps**: OPFS with quota monitoring
|
||||
4. **Distributed**: S3/GCS/Azure with Intelligent-Tiering/Autoclass
|
||||
|
||||
### Optimize for Your Use Case
|
||||
1. **Read-heavy**: Enable aggressive caching
|
||||
2. **Write-heavy**: Batch operations
|
||||
1. **Read-heavy**: Enable aggressive caching + cloud CDN
|
||||
2. **Write-heavy**: Batch operations + async writes
|
||||
3. **Real-time**: FileSystem with periodic snapshots
|
||||
4. **Archival**: S3 with compression
|
||||
4. **Archival**: Cloud storage with lifecycle policies (96% cost savings!)
|
||||
5. **Large-scale**: Metadata/vector separation + UUID sharding + lifecycle policies
|
||||
|
||||
### v4.0.0 Cost Optimization
|
||||
1. **Enable lifecycle policies** for cloud storage (automated cost reduction)
|
||||
2. **Use Intelligent-Tiering (S3)** or Autoclass (GCS) for automatic optimization
|
||||
3. **Enable compression** for FileSystem storage (60-80% space savings)
|
||||
4. **Monitor quota** for OPFS (prevent quota exceeded errors)
|
||||
5. **Use batch operations** for bulk deletions (efficient API usage)
|
||||
6. **Consider tier management** for Azure (Hot/Cool/Archive tiers)
|
||||
|
||||
**Example Cost Savings (500TB dataset):**
|
||||
- Without lifecycle policies: **$138,000/year**
|
||||
- With v4.0.0 lifecycle policies: **$5,940/year**
|
||||
- **Savings: $132,060/year (96%)**
|
||||
|
||||
### Monitor and Maintain
|
||||
1. Regular statistics collection
|
||||
2. Monitor lifecycle policy effectiveness
|
||||
3. Index optimization
|
||||
4. Cache tuning based on hit rates
|
||||
5. Track storage costs and tier distribution
|
||||
6. Review quota usage (OPFS) and storage growth patterns
|
||||
|
||||
