# Storage Architecture
|
||||
|
||||
Brainy implements a sophisticated, unified storage system that works across all environments (Node.js, Browser, Edge Workers) with enterprise-grade features like metadata indexing, entity registry, and write-ahead logging.
|
||||
|
||||
## Storage Structure
|
||||
|
||||
```
|
||||
brainy-data/
|
||||
├── _system/ # System management
|
||||
│ └── statistics.json # Performance metrics and statistics
|
||||

|
||||
│ └── {uuid}.json # Individual entity documents
|
||||

|
||||
└── locks/ # Concurrent access control
|
||||
└── {resource}.lock # Resource locks
|
||||
```
|
||||
|
||||
## Storage Adapters
|
||||
|
||||
Brainy provides multiple storage adapters with identical APIs:
|
||||
|
||||
### FileSystem Storage (Node.js)
|
||||
```typescript
|
||||
const brain = new BrainyData({
|
||||
storage: {
|
||||
type: 'filesystem',
|
||||
path: './data'
|
||||
}
|
||||
})
|
||||
```
|
||||
- **Use case**: Server applications, CLI tools
|
||||
- **Performance**: Direct file I/O
|
||||
- **Persistence**: Permanent on disk
|
||||
|
||||
### S3 Compatible Storage
|
||||
```typescript
|
||||
const brain = new BrainyData({
|
||||
storage: {
|
||||
type: 's3',
|
||||
bucket: 'my-brainy-data',
|
||||
region: 'us-east-1',
|
||||
credentials: {
|
||||
accessKeyId: process.env.AWS_ACCESS_KEY_ID,
|
||||
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
- **Use case**: Distributed applications, cloud deployments
|
||||
- **Performance**: Network dependent, with intelligent caching
|
||||
- **Persistence**: Cloud storage durability
|
||||
|
||||
### Origin Private File System (Browser)
|
||||
```typescript
|
||||
const brain = new BrainyData({
|
||||
storage: {
|
||||
type: 'opfs'
|
||||
}
|
||||
})
|
||||
```
|
||||
- **Use case**: Browser applications, PWAs
|
||||
- **Performance**: Near-native file system speed
|
||||
- **Persistence**: Permanent in browser (with quota limits)
|
||||
|
||||
### Memory Storage
|
||||
```typescript
|
||||
const brain = new BrainyData({
|
||||
storage: {
|
||||
type: 'memory'
|
||||
}
|
||||
})
|
||||
```
|
||||
- **Use case**: Testing, temporary processing
|
||||
- **Performance**: Fastest possible
|
||||
- **Persistence**: Volatile (lost on restart)
|
||||
|
||||
## Metadata Indexing System
|
||||
|
||||
### Field Discovery Index
|
||||
Tracks all unique values for each field:
|
||||
|
||||
```json
|
||||
// __metadata_field_index__field_category.json
|
||||
{
|
||||
"values": {
|
||||
"technology": 45,
|
||||
"science": 32,
|
||||
"business": 28
|
||||
},
|
||||
"lastUpdated": 1699564234567
|
||||
}
|
||||
```
|
||||
|
||||
### Value-Based Indexes
|
||||
Maps field+value combinations to entity IDs:
|
||||
|
||||
```json
|
||||
// __metadata_index__category_technology_chunk0.json
|
||||
{
|
||||
"field": "category",
|
||||
"value": "technology",
|
||||
"ids": ["uuid1", "uuid2", "uuid3", ...],
|
||||
"chunk": 0,
|
||||
"total": 45
|
||||
}
|
||||
```
|
||||
|
||||
### Index Chunking
|
||||
Large indexes automatically chunk for performance:
|
||||
- **Chunk size**: 10,000 IDs per chunk
|
||||
- **Auto-splitting**: Transparent to queries
|
||||
- **Parallel loading**: Chunks load on demand
|
||||
|
||||
## Entity Registry
|
||||
|
||||
High-performance deduplication system for streaming data:
|
||||
|
||||
### Registry Structure
|
||||
```json
|
||||
// __entity_registry__.json
|
||||
{
|
||||
"mappings": {
|
||||
"did:plc:alice123": "550e8400-e29b-41d4-a716-446655440000",
|
||||
"handle:alice.bsky.social": "550e8400-e29b-41d4-a716-446655440000"
|
||||
},
|
||||
"stats": {
|
||||
"totalMappings": 10000,
|
||||
"lastSync": 1699564234567
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Performance Characteristics
|
||||
- **Lookup**: O(1) in-memory hash map
|
||||
- **Persistence**: Configurable (memory/storage/hybrid)
|
||||
- **Cache**: LRU with configurable TTL
|
||||
- **Sync**: Periodic or on-demand
|
||||
|
||||
## Write-Ahead Logging (WAL)
|
||||
|
||||
Ensures durability and enables recovery:
|
||||
|
||||
### WAL Entry Format
|
||||
```json
|
||||
{
|
||||
"timestamp": 1699564234567,
|
||||
"operation": "add",
|
||||
"data": {
|
||||
"id": "550e8400-e29b-41d4-a716-446655440000",
|
||||
"content": "...",
|
||||
"metadata": {}
|
||||
},
|
||||
"checksum": "sha256:..."
|
||||
}
|
||||
```
|
||||
|
||||
### Recovery Process
|
||||
1. On startup, check for WAL files
|
||||
2. Replay operations from last checkpoint
|
||||
3. Verify checksums for integrity
|
||||
4. Clean up processed WAL files
|
||||
|
||||
## Storage Optimization
|
||||
|
||||
### Compression
|
||||
- **JSON**: Automatic minification
|
||||
- **Vectors**: Float32 to Uint8 quantization option
|
||||
- **Indexes**: Binary format for large datasets
|
||||
|
||||
### Caching Strategy
|
||||
```typescript
|
||||
// Configure caching per storage type
|
||||
const brain = new BrainyData({
|
||||
storage: {
|
||||
type: 'filesystem',
|
||||
cache: {
|
||||
enabled: true,
|
||||
maxSize: 1000, // Maximum cached items
|
||||
ttl: 300000, // 5 minutes
|
||||
strategy: 'lru' // Least recently used
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Batch Operations
|
||||
```typescript
|
||||
// Batch writes for performance
|
||||
await brain.addBatch([
|
||||
{ content: "item1", metadata: {} },
|
||||
{ content: "item2", metadata: {} },
|
||||
{ content: "item3", metadata: {} }
|
||||
])
|
||||
// Single transaction, optimized I/O
|
||||
```
|
||||
|
||||
## Concurrent Access
|
||||
|
||||
### Locking Mechanism
|
||||
```typescript
|
||||
// Automatic locking for write operations
|
||||
await brain.storage.withLock('resource-id', async () => {
|
||||
// Exclusive access to resource
|
||||
await brain.storage.saveNoun(id, data)
|
||||
})
|
||||
```
|
||||
|
||||
### Read-Write Separation
|
||||
- **Reads**: Non-blocking, parallel
|
||||
- **Writes**: Serialized with locks
|
||||
- **Hybrid**: Read-heavy optimization
|
||||
|
||||
## Migration and Backup
|
||||
|
||||
### Export Data
|
||||
```typescript
|
||||
// Export entire database
|
||||
const backup = await brain.export({
|
||||
format: 'json',
|
||||
includeVectors: true,
|
||||
includeIndexes: false
|
||||
})
|
||||
```
|
||||
|
||||
### Import Data
|
||||
```typescript
|
||||
// Import from backup
|
||||
await brain.import(backup, {
|
||||
mode: 'merge', // or 'replace'
|
||||
validateSchema: true
|
||||
})
|
||||
```
|
||||
|
||||
### Storage Migration
|
||||
```typescript
|
||||
// Migrate between storage types
|
||||
const oldBrain = new BrainyData({ storage: { type: 'filesystem' } })
|
||||
const newBrain = new BrainyData({ storage: { type: 's3' } })
|
||||
|
||||
await oldBrain.init()
|
||||
await newBrain.init()
|
||||
|
||||
// Transfer all data
|
||||
const data = await oldBrain.export()
|
||||
await newBrain.import(data)
|
||||
```
|
||||
|
||||
## Performance Tuning
|
||||
|
||||
### Storage-Specific Optimizations
|
||||
|
||||
#### FileSystem
|
||||
- **Directory sharding**: Split files across subdirectories
|
||||
- **Async I/O**: Non-blocking file operations
|
||||
- **Buffer pooling**: Reuse buffers for efficiency
|
||||
|
||||
#### S3
|
||||
- **Multipart uploads**: For large objects
|
||||
- **Request batching**: Combine small operations
|
||||
- **CDN integration**: Edge caching for reads
|
||||
|
||||
#### OPFS
|
||||
- **Quota management**: Monitor and request increases
|
||||
- **Worker offloading**: Heavy operations in workers
|
||||
- **Transaction batching**: Group operations
|
||||
|
||||
### Monitoring
|
||||
|
||||
```typescript
|
||||
// Get storage statistics
|
||||
const stats = await brain.storage.getStatistics()
|
||||
console.log(stats)
|
||||
// {
|
||||
// totalSize: 1048576,
|
||||
// entityCount: 1000,
|
||||
// indexSize: 204800,
|
||||
// walSize: 10240,
|
||||
// cacheHitRate: 0.85
|
||||
// }
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Choose the Right Adapter
|
||||
1. **Development**: Memory or FileSystem
|
||||
2. **Production Server**: FileSystem or S3
|
||||
3. **Browser Apps**: OPFS or Memory
|
||||
4. **Distributed**: S3 with caching
|
||||
|
||||
### Optimize for Your Use Case
|
||||
1. **Read-heavy**: Enable aggressive caching
|
||||
2. **Write-heavy**: Use WAL and batching
|
||||
3. **Real-time**: Memory with periodic persistence
|
||||
4. **Archival**: S3 with compression
|
||||
|
||||
### Monitor and Maintain
|
||||
1. Regular statistics collection
|
||||
2. WAL cleanup scheduling
|
||||
3. Index optimization
|
||||
4. Cache tuning based on hit rates
