## 🏆 Industry First: True Vector + Graph Database
|
||||
|
||||
**Brainy is the only database that natively combines vector search and graph relationships in a single, unified system.**
|
||||
|
||||
Unlike other solutions that bolt vector search onto traditional databases or require multiple systems:
|
||||
|
||||
✅ **Native Vector + Graph Architecture** - Purpose-built for both semantic search AND knowledge graphs
|
||||
✅ **Single API, Dual Power** - Vector similarity search AND graph traversal in one database
|
||||
✅ **True Semantic Relationships** - Not just "similar vectors" but meaningful connections like "develops", "owns", "causes"
|
||||
✅ **Zero Integration Complexity** - No need to sync between Pinecone + Neo4j or pgvector + graph databases
|
||||
|
||||
**Why This Matters:**
|
||||
```javascript
|
||||
// Other solutions: Manage 2+ databases
|
||||
const vectors = await pinecone.search(query) // Vector search
|
||||
const graph = await neo4j.run("MATCH (a)-[r]->(b)") // Graph traversal
|
||||
// How do you keep them in sync? 😢
|
||||
|
||||
// Brainy: One database, both capabilities
|
||||
const results = await brainy.search("AI models", 10, {
|
||||
includeVerbs: true, // Include relationships
|
||||
verbTypes: ["develops"] // Filter by relationship type
|
||||
})
|
||||
// Everything stays perfectly synchronized! 🎉
|
||||
```
|
||||
|
||||
This revolutionary architecture enables entirely new classes of AI applications that were previously impossible or prohibitively complex.
|
||||
|
||||

# Storage Adapters
|
||||
|
||||
Brainy's storage system is designed for universal compatibility through a simple, powerful abstraction layer. Any storage system that can handle key-value operations can be used as a Brainy backend.
|
||||
|
||||
## 🌍 Universal Storage Architecture
|
||||
|
||||
**One Interface, Any Storage System.** Brainy works with virtually any data store through its `StorageAdapter` interface.
|
||||
|
||||
### Currently Supported Storage Systems
|
||||
|
||||
| Storage Type | Environment | Use Case | Status |
|
||||
|--------------|-------------|----------|---------|
|
||||
| **S3-Compatible** | Production | AWS S3, Cloudflare R2, MinIO, DigitalOcean Spaces | ✅ Production Ready |
|
||||
| **File System** | Node.js/Server | Local development, dedicated servers | ✅ Production Ready |
|
||||
| **OPFS (Origin Private File System)** | Browser | Modern web apps, PWAs | ✅ Production Ready |
|
||||
| **Memory Storage** | Any | Testing, caching, temporary data | ✅ Production Ready |
|
||||
|
||||
### 🚀 Easily Add New Storage Backends
|
||||
|
||||
**Want to use a database that's not listed? No problem!** Creating a new storage adapter is straightforward because Brainy only requires these simple operations:
|
||||
|
||||
```typescript
|
||||
interface StorageAdapter {
|
||||
// Basic key-value operations
|
||||
saveMetadata(id: string, data: any): Promise<void>
|
||||
getMetadata(id: string): Promise<any | null>
|
||||
|
||||
// Entity operations (built on top of metadata)
|
||||
saveNoun(noun: HNSWNoun): Promise<void>
|
||||
getNoun(id: string): Promise<HNSWNoun | null>
|
||||
|
||||
// Pagination support
|
||||
getNouns(options?: PaginationOptions): Promise<PaginatedResult<HNSWNoun>>
|
||||
getVerbs(options?: PaginationOptions): Promise<PaginatedResult<GraphVerb>>
|
||||
|
||||
// Lifecycle
|
||||
init(): Promise<void>
|
||||
clear(): Promise<void>
|
||||
}
|
||||
```
|
||||
|
||||

## 💡 How Storage Adapters Work
|
||||
|
||||
### Simple Key-Value Foundation
|
||||
|
||||
All Brainy storage is built on a simple principle: **everything is stored as JSON objects with unique keys**.
|
||||
|
||||
```typescript
|
||||
// This is all your storage needs to support:
|
||||
await storage.saveMetadata("user_123", {
|
||||
name: "John Doe",
|
||||
type: "person",
|
||||
email: "john@example.com"
|
||||
})
|
||||
|
||||
const user = await storage.getMetadata("user_123")
|
||||
// Returns: { name: "John Doe", type: "person", email: "john@example.com" }
|
||||
```
|
||||
|
||||
### Automatic Index Management
|
||||
|
||||
The metadata indexing system automatically handles complex operations:
|
||||
|
||||
```typescript
|
||||
// Brainy automatically creates these index entries:
|
||||
await storage.saveMetadata("__metadata_index__type_person_chunk0", {
|
||||
field: "type",
|
||||
value: "person",
|
||||
ids: ["user_123", "user_456", ...]
|
||||
})
|
||||
|
||||
await storage.saveMetadata("__metadata_field_index__type", {
|
||||
values: { "person": 50, "company": 23, "product": 12 }
|
||||
})
|
||||
```
|
||||
|
||||
### Directory Structure
|
||||
|
||||
Storage adapters use a logical directory structure that maps to your storage system:
|
||||
|
||||
```
|
||||
entities/
|
||||
├── nouns/
|
||||
│ ├── vectors/ # Vector data for semantic search
|
||||
│ │ ├── user_123.json
|
||||
│ │ └── company_456.json
|
||||
│ └── metadata/ # Metadata + automatic indexes
|
||||
│ ├── user_123.json # User metadata
|
||||
│ ├── __metadata_index__type_person_chunk0.json # Index entries
|
||||
│ └── __metadata_field_index__type.json # Field values
|
||||
└── verbs/
|
||||
├── vectors/ # Relationship vectors
|
||||
└── metadata/ # Relationship metadata + indexes
|
||||
```
|
||||
|
||||
## 🛠️ Creating a Custom Storage Adapter
|
||||
|
||||
### Step 1: Implement the Interface
|
||||
|
||||
```typescript
|
||||
import { BaseStorage } from '@soulcraft/brainy'
|
||||
|
||||
export class MyCustomStorage extends BaseStorage {
|
||||
private client: MyDatabaseClient
|
||||
|
||||
async init(): Promise<void> {
|
||||
this.client = new MyDatabaseClient(this.config)
|
||||
await this.client.connect()
|
||||
this.isInitialized = true
|
||||
}
|
||||
|
||||
async saveMetadata(id: string, metadata: any): Promise<void> {
|
||||
// Map to your database's put/insert operation
|
||||
await this.client.put(id, JSON.stringify(metadata))
|
||||
}
|
||||
|
||||
async getMetadata(id: string): Promise<any | null> {
|
||||
// Map to your database's get/select operation
|
||||
const result = await this.client.get(id)
|
||||
return result ? JSON.parse(result) : null
|
||||
}
|
||||
|
||||
// Implement other required methods...
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2: Use Your Custom Adapter
|
||||
|
||||
```typescript
|
||||
import { BrainyData } from '@soulcraft/brainy'
|
||||
import { MyCustomStorage } from './my-custom-storage'
|
||||
|
||||
const brainy = new BrainyData({
|
||||
storage: {
|
||||
custom: new MyCustomStorage({
|
||||
connectionString: 'your-db-connection-string',
|
||||
database: 'brainy-vectors'
|
||||
})
|
||||
}
|
||||
})
|
||||
|
||||
await brainy.init()
|
||||
// Now Brainy uses your custom storage backend!
|
||||
```
|
||||
|
||||
## 🏗️ Implementation Examples
|
||||
|
||||
### Redis Storage Adapter
|
||||
|
||||
```typescript
|
||||
export class RedisStorage extends BaseStorage {
|
||||
private redis: Redis
|
||||
|
||||
async saveMetadata(id: string, data: any): Promise<void> {
|
||||
await this.redis.set(id, JSON.stringify(data))
|
||||
}
|
||||
|
||||
async getMetadata(id: string): Promise<any | null> {
|
||||
const result = await this.redis.get(id)
|
||||
return result ? JSON.parse(result) : null
|
||||
}
|
||||
|
||||
async getNouns(options?: PaginationOptions): Promise<PaginatedResult<HNSWNoun>> {
|
||||
const cursor = options?.cursor || '0'
|
||||
const limit = options?.limit || 100
|
||||
|
||||
const [newCursor, keys] = await this.redis.scan(cursor, 'MATCH', 'entities/nouns/vectors/*', 'COUNT', limit)
|
||||
|
||||
const nouns: HNSWNoun[] = []
|
||||
for (const key of keys) {
|
||||
const data = await this.redis.get(key)
|
||||
if (data) {
|
||||
nouns.push(this.parseNoun(JSON.parse(data)))
|
||||
}
|
||||
}
|
||||
|
||||
return {
|
||||
items: nouns,
|
||||
hasMore: newCursor !== '0',
|
||||
nextCursor: newCursor !== '0' ? newCursor : undefined
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### MongoDB Storage Adapter
|
||||
|
||||
```typescript
|
||||
export class MongoStorage extends BaseStorage {
|
||||
private db: MongoDatabase
|
||||
|
||||
async saveMetadata(id: string, data: any): Promise<void> {
|
||||
const collection = this.getCollectionForId(id)
|
||||
await collection.replaceOne(
|
||||
{ _id: id },
|
||||
{ _id: id, data },
|
||||
{ upsert: true }
|
||||
)
|
||||
}
|
||||
|
||||
async getMetadata(id: string): Promise<any | null> {
|
||||
const collection = this.getCollectionForId(id)
|
||||
const doc = await collection.findOne({ _id: id })
|
||||
return doc?.data || null
|
||||
}
|
||||
|
||||
private getCollectionForId(id: string): Collection {
|
||||
// Route different entity types to different collections for optimization
|
||||
if (id.startsWith('entities/nouns/')) return this.db.collection('nouns')
|
||||
if (id.startsWith('entities/verbs/')) return this.db.collection('verbs')
|
||||
if (id.startsWith('__metadata_index__')) return this.db.collection('indexes')
|
||||
return this.db.collection('metadata')
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🚀 Why This Architecture is Powerful
|
||||
|
||||
### 1. **Storage-Agnostic Intelligence**
|
||||
All of Brainy's smart features work with any storage backend:
|
||||
- Metadata indexing
|
||||
- Filter discovery
|
||||
- Pagination
|
||||
- Caching
|
||||
- Real-time updates
|
||||
|
||||
### 2. **Performance Optimization**
|
||||
Each adapter can optimize for its storage type:
|
||||
- **Redis**: Leverage Redis pipelines and data structures
|
||||
- **MongoDB**: Use MongoDB aggregation pipelines
|
||||
- **SQL**: Optimize with proper indexes and queries
|
||||
- **S3**: Batch operations and intelligent prefixing
|
||||
|
||||
### 3. **Zero Migration Lock-In**
|
||||
Switch storage backends without changing your application code:
|
||||
```typescript
|
||||
// Development: File system
|
||||
const devBrainy = new BrainyData({ storage: { fileSystem: { path: './data' } } })
|
||||
|
||||
// Production: S3
|
||||
const prodBrainy = new BrainyData({ storage: { s3Storage: { bucketName: 'prod-vectors' } } })
|
||||
|
||||
// Same API, different storage!
|
||||
```
|
||||
|
||||
### 4. **Hybrid Deployments**
|
||||
Use different storage for different use cases:
|
||||
```typescript
|
||||
// Writers use S3 for durability
|
||||
const writer = new BrainyData({
|
||||
storage: { s3Storage: { bucketName: 'durable-storage' } }
|
||||
})
|
||||
|
||||
// Readers use Redis for speed
|
||||
const reader = new BrainyData({
|
||||
storage: { redis: { connectionString: 'redis://cache' } }
|
||||
})
|
||||
```
|
||||
|
||||
