docs: Major documentation cleanup and accuracy fixes for 1.0
✨ RESTORED the 9th method - augment() for infinite extensibility! REMOVED (20 files): - All business strategy and revenue projection documents - Misleading Cortex CLI documentation - Outdated duplicate documentation - Internal technical analysis files FIXED: - ✅ Corrected to 9 unified methods (was incorrectly showing 8) - ✅ The 9th method `augment()` enables methods 10→∞ - ✅ Removed non-existent CLI commands (add-noun, add-verb) - ✅ Brain Cloud marked as "Early Access" with real pricing - ✅ Aligned with actual soulcraft.com offerings - ✅ All code examples now match actual implementation CONSOLIDATED: - Combined 3 augmentation docs into single AUGMENTATIONS.md - Removed duplicate quick-start guides ADDED: - cleanup-git-history.sh script for removing sensitive files from history - Clear Brain Cloud pricing tiers ($19 Cloud Sync, $99 Enterprise) - Transparency about optional services sustaining development All documentation is now accurate, honest, and appropriate for an MIT open source project with optional cloud services.

|
||||
# Single question mode
|
||||
```
|
||||
|
||||
### Configure LLM (Optional)
|
||||
```bash
|
||||
# Store API keys securely
|
||||
cortex config set ANTHROPIC_API_KEY sk-ant-... --encrypt

|
||||
```bash
|
||||
# Basic relationship
|
||||
cortex verb user-123 likes product-456
|
||||
|
||||

|
||||
cortex verb company-A invests_in startup-B --metadata '{
|
||||
"amount": 5000000,
|
||||
"date": "2024-01-15",
|
||||
"round": "Series A"
|
||||
}'
|

|
||||
```
|
||||
|
||||
### Interactive Graph Explorer
|
||||
```bash
|
||||
cortex explore user-123
|
||||
# Opens interactive graph navigation:
|
||||
# - View node details and metadata
|
||||
# - See all connections
|
||||
# - Navigate to connected nodes
|
||||
# - Add new connections
|
||||
# - Find similar nodes
|
||||
|
||||
cortex graph # Alias for explore
|
||||
```
|
||||
|
||||
### Graph Patterns
|
||||
```bash
|
||||
# Social network
|
||||
cortex verb user-1 follows user-2
|
||||
cortex verb user-1 likes post-123
|
||||
cortex verb post-123 tagged_with ai
|
||||
|
||||
# Knowledge graph
|
||||
cortex verb article-1 references paper-2
|
||||
cortex verb paper-2 authored_by researcher-3
|
||||
cortex verb researcher-3 works_at university-4
|
||||
|
||||
# E-commerce
|
||||
cortex verb customer-1 purchased product-2
|
||||
cortex verb product-2 belongs_to category-3
|
||||
cortex verb customer-1 reviewed product-2
|
||||
```
|
||||
|
||||
## Configuration Management
|
||||
|
||||
### Secure Configuration Storage
|
||||
```bash
|
||||
# Set configuration (auto-encrypts secrets)
|
||||
cortex config set DATABASE_URL postgres://localhost/mydb
|
||||
cortex config set STRIPE_KEY sk_live_... --encrypt
|
||||
cortex config set API_ENDPOINT https://api.example.com
|
||||
|
||||
# Get configuration
|
||||
cortex config get DATABASE_URL
|
||||
|
||||
# List all configuration
|
||||
cortex config list
|
||||
|
||||
# Import from .env file
|
||||
cortex config import .env.production
|
||||
```
|
||||
|
||||
### Use in Your Application
|
||||
```javascript
|
||||
import { BrainyData } from '@soulcraft/brainy'
|
||||
|
||||
const brainy = new BrainyData()
|
||||
await brainy.loadEnvironment() // Loads all Cortex configs
|
||||
|
||||
// All configs are now in process.env
|
||||
console.log(process.env.DATABASE_URL) // Automatically decrypted
|
||||
```
|
||||
|
||||
## Storage Migration
|
||||
|
||||
### Migrate Between Storage Providers
|
||||
```bash
|
||||
# Migrate from filesystem to S3
|
||||
cortex migrate --to s3 --bucket my-production-data
|
||||
|
||||
# Migrate from S3 to GCS
|
||||
cortex migrate --to gcs --bucket my-gcs-bucket
|
||||
|
||||
# Migration strategies
|
||||
cortex migrate --to s3 --bucket new-bucket --strategy gradual
|
||||
# gradual: Migrate in batches with verification
|
||||
# immediate: Migrate all at once
|
||||
```
|
||||
|
||||
### Zero-Downtime Migration
|
||||
```javascript
|
||||
// Your app code doesn't change!
|
||||
const brainy = new BrainyData() // Auto-detects new storage
|
||||
await brainy.init() // Works with any storage
|
||||
```
|
||||
|
||||

|
||||
|
||||
# Export for deployment
|
||||
cortex config list > configs.json
|
||||
```
|
||||
|
||||
## Tips and Best Practices
|
||||
|
||||
### 1. Start with Chat
|
||||
Begin by talking to your data to understand patterns:
|
||||
```bash
|
||||
cortex chat
|
||||
> "Show me the most connected nodes"
|
||||
> "What patterns exist in user behavior?"
|
||||
> "Find anomalies in the data"
|
||||
```
|
||||
|
||||
### 2. Use Graph for Relationships
|
||||
Model your domain with verbs:
|
||||
```bash
|
||||
# Instead of nested JSON, use graph relationships
|
||||
cortex verb user-1 owns account-1
|
||||
cortex verb account-1 contains transaction-1
|
||||
cortex verb transaction-1 paid_to merchant-1
|
||||
```
|
||||
|
||||
### 3. Combine Search Types
|
||||
Vector + Graph + Filters = Powerful queries:
|
||||
```bash
|
||||
cortex search "fraud" \
|
||||
--verbs "transacted_with,connected_to" \
|
||||
--filter '{"risk_score": {"$gte": 0.7}}' \
|
||||
--depth 2
|
||||
```
|
||||
|
||||
### 4. Secure Secrets
|
||||
Always encrypt sensitive data:
|
||||
```bash
|
||||
cortex config set API_KEY value --encrypt
|
||||
cortex config set PASSWORD value --encrypt
|
||||
cortex config set SECRET value --encrypt
|
||||
```
|
||||
|
||||
### 5. Interactive Exploration
|
||||
Use interactive modes for discovery:
|
||||
```bash
|
||||
cortex search-advanced # Guided search
|
||||
cortex explore # Graph navigation
|
||||
cortex chat # Conversational interface
|
||||
```
|
||||
|
||||
## Platform Support
|
||||
|
||||
⚠️ **Note**: Cortex is a **Node.js-only** feature designed for:
|
||||
- Server-side applications
|
||||
- CLI tools and scripts
|
||||
- Backend services
|
||||
- Development environments
|
||||
|
||||
Browser applications should use the Brainy JavaScript API directly.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Cortex not found**
|
||||
```bash
|
||||
npm install -g @soulcraft/brainy
|
||||
# or use npx
|
||||
npx cortex init
|
||||
```
|
||||
|
||||
**Permission denied**
|
||||
```bash
|
||||
chmod +x node_modules/.bin/cortex
|
||||
```
|
||||
|
||||
**Storage migration fails**
|
||||
```bash
|
||||
# Check credentials
|
||||
cortex config get AWS_ACCESS_KEY_ID
|
||||
# Verify bucket exists
|
||||
aws s3 ls s3://your-bucket
|
||||
```
|
||||
|
||||
**Chat not working**
|
||||
```bash
|
||||
# Check LLM configuration
|
||||
cortex config get ANTHROPIC_API_KEY
|
||||
# Test without LLM
|
||||
cortex chat # Works with templates
|
||||
```
|
||||
|
||||

t# Brainy Distributed Enhancements - Revised Implementation Plan
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Based on analysis of multi-writer scenarios and the need for unified search across diverse data types, this document presents a practical 3-phase approach to distributed Brainy deployment. The focus is on maximizing search performance and relevance while minimizing complexity for users and developers.
|
||||
|
||||
## Key Design Decisions
|
||||
|
||||
1. **Hash-based partitioning** for multi-writer scenarios (instead of semantic partitioning)
|
||||
2. **Shared JSON config** in S3 for coordination (simple, debuggable)
|
||||
3. **Automatic mode** by default with progressive disclosure for advanced users
|
||||
4. **Domain tagging** for logical data separation while maintaining unified search
|
||||
|
||||
## Phase 1: Foundation (3-4 days) - High Benefit, Low Complexity
|
||||
|
||||
### 1.1 Shared Configuration System
|
||||
|
||||
Simple JSON config file at `_brainy/config.json` in S3 bucket:
|
||||
|
||||
```typescript
|
||||
// Auto-generated config structure

```
|
||||
|
||||
**Implementation:**
|
||||
```typescript
|
||||
// src/config/distributedConfig.ts
|
||||
export class DistributedConfigManager {
|
||||
private config: SharedConfig;
|
||||
|
||||
async initialize() {
|
||||
// Try to load existing config
|
||||
this.config = await this.loadOrCreateConfig();
|
||||
|
||||
// Auto-register this instance
|
||||
await this.registerInstance();
|
||||
|
||||
// Start heartbeat and config watching
|
||||
this.startHeartbeat();
|
||||
this.watchConfig();
|
||||
}
|
||||
|
||||
private async loadOrCreateConfig(): Promise<SharedConfig> {
|
||||
try {
|
||||
return await this.s3.getJSON('_brainy/config.json');
|
||||
} catch (err) {
|
||||
if (err.code === 'NoSuchKey') {
|
||||
// First instance - create config
|
||||
const newConfig = this.createDefaultConfig();
|
||||
await this.s3.putJSON('_brainy/config.json', newConfig);
|
||||
return newConfig;
|
||||
}
|
||||
throw err;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**User Experience:**
|
||||
```typescript
|
||||
// No change for single instance!
|
||||
const brainy = new BrainyData({
|
||||
storage: { type: 's3', bucket: 'my-bucket' }
|
||||
});
|
||||
|
||||
// Distributed with zero config
|
||||
const brainy = new BrainyData({
|
||||
storage: { type: 's3', bucket: 'my-bucket' },
|
||||
distributed: true // Auto-detect role!
|
||||
});
|
||||
```
|
||||
|
||||
### 1.2 Automatic Role Detection
|
||||
|
||||
```typescript
|
||||
export class RoleManager {
|
||||
async determineRole(): Promise<'reader' | 'writer'> {
|
||||
// Check environment hints
|
||||
if (process.env.BRAINY_ROLE) {
|
||||
return process.env.BRAINY_ROLE as 'reader' | 'writer';
|
||||
}
|
||||
|
||||
// Check if running in Lambda (typically read-heavy)
|
||||
if (process.env.AWS_LAMBDA_FUNCTION_NAME) {
|
||||
return 'reader';
|
||||
}
|
||||
|
||||
// Check existing instances
|
||||
const config = await this.loadConfig();
|
||||
const writers = Object.values(config.instances)
|
||||
.filter(i => i.role === 'writer' && this.isAlive(i));
|
||||
|
||||
// First writer or no writers alive
|
||||
if (writers.length === 0) {
|
||||
return 'writer';
|
||||
}
|
||||
|
||||
// Default to reader
|
||||
return 'reader';
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 1.3 Hash-Based Partitioning
|
||||
|
||||
Replace semantic partitioning with deterministic hashing for multi-writer compatibility:
|
||||
|
||||
```typescript
|
||||
// src/partitioning/hashPartitioner.ts
|
||||
export class HashPartitioner {
|
||||
private partitionCount: number;
|
||||
|
||||
constructor(config: SharedConfig) {
|
||||
this.partitionCount = config.settings.partitionCount;
|
||||
}
|
||||
|
||||
getPartition(vectorId: string): string {
|
||||
// Deterministic hash - same ID always goes to same partition
|
||||
const hash = this.xxhash(vectorId);
|
||||
const partitionIndex = hash % this.partitionCount;
|
||||
return `vectors/p${partitionIndex.toString().padStart(3, '0')}`;
|
||||
}
|
||||
|
||||
// For domain separation while maintaining unified structure
|
||||
getPartitionWithDomain(vectorId: string, domain: string): string {
|
||||
const basePartition = this.getPartition(vectorId);
|
||||
// Store domain as metadata, not in path
|
||||
return basePartition;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- ✅ Writers can write to any partition (no coordination needed)
|
||||
- ✅ Even distribution of data
|
||||
- ✅ Readers search all partitions uniformly
|
||||
- ✅ No semantic coherence issues with mixed data types
|
||||
|
||||
## Phase 2: Optimization (2-3 days) - Medium Benefit, Low Complexity
|
||||
|
||||
### 2.1 Role-Optimized Caching
|
||||
|
||||
```typescript
|
||||
// src/modes/operationalModes.ts
|
||||
export class ReaderMode {
|
||||
getCacheConfig() {
|
||||
return {
|
||||
hotCacheRatio: 0.8, // 80% memory for read cache
|
||||
prefetchAggressive: true, // Prefetch neighboring vectors
|
||||
ttl: 3600000, // 1 hour cache TTL
|
||||
compressionEnabled: true // Trade CPU for memory
|
||||
};
|
||||
}
|
||||
}
|
||||
|
||||
export class WriterMode {
|
||||
getCacheConfig() {
|
||||
return {
|
||||
hotCacheRatio: 0.2, // 20% memory, focus on write buffer
|
||||
writeBufferSize: 10000, // Batch writes
|
||||
ttl: 60000, // Short TTL
|
||||
compressionEnabled: false // Speed over memory
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2.2 Domain Metadata System
|
||||
|
||||
Enable filtering while maintaining unified search:
|
||||
|
||||
```typescript
|
||||
// Automatic domain detection
|
||||
export class DomainDetector {
|
||||
detectDomain(data: any): string {
|
||||
// Auto-detect based on data shape
|
||||
if (data.symptoms || data.diagnosis) return 'medical';
|
||||
if (data.contract || data.clause) return 'legal';
|
||||
if (data.price || data.sku) return 'product';
|
||||
return 'general';
|
||||
}
|
||||
}
|
||||
|
||||
// Writers automatically tag domains
|
||||
await brainy.add(vector, {
|
||||
id: vectorId,
|
||||
domain: this.detectDomain(originalData),
|
||||
...metadata
|
||||
});
|
||||
|
||||
// Readers can search all or filter
|
||||
const results = await brainy.search(query); // Search all domains
|
||||
const medical = await brainy.search(query, {
|
||||
filter: { domain: 'medical' }
|
||||
});
|
||||
```
|
||||
|
||||
### 2.3 Simple Health Monitoring
|
||||
|
||||
```typescript
|
||||
// src/monitoring/health.ts
|
||||
export class HealthMonitor {
|
||||
async updateHealth() {
|
||||
const health = {
|
||||
instanceId: this.instanceId,
|
||||
role: this.role,
|
||||
status: 'healthy',
|
||||
lastHeartbeat: new Date().toISOString(),
|
||||
metrics: {
|
||||
vectorCount: await this.getVectorCount(),
|
||||
cacheHitRate: this.getCacheStats().hitRate,
|
||||
memoryUsage: process.memoryUsage().heapUsed
|
||||
}
|
||||
};
|
||||
|
||||
// Update in config
|
||||
const config = await this.loadConfig();
|
||||
config.instances[this.instanceId] = health;
|
||||
await this.saveConfig(config);
|
||||
}
|
||||
|
||||
// Auto-cleanup stale instances
|
||||
async cleanupStale() {
|
||||
const config = await this.loadConfig();
|
||||
const now = Date.now();
|
||||
|
||||
for (const [id, instance] of Object.entries(config.instances)) {
|
||||
const lastSeen = new Date(instance.lastHeartbeat).getTime();
|
||||
if (now - lastSeen > 60000) { // 60s timeout
|
||||
delete config.instances[id];
|
||||
}
|
||||
}
|
||||
|
||||
await this.saveConfig(config);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**User Experience:**
|
||||
```typescript
|
||||
// Still zero config!
|
||||
const brainy = new BrainyData({
|
||||
storage: { type: 's3', bucket: 'my-bucket' },
|
||||
distributed: true
|
||||
});
|
||||
|
||||
// Optional: specify domain for better organization
|
||||
await brainy.add(vector, {
|
||||
domain: 'medical', // Optional hint
|
||||
...data
|
||||
});
|
||||
```
|
||||
|
||||
## Phase 3: Advanced Features (Optional, 3-4 days)
|
||||
|
||||
### 3.1 Partition Affinity (Reduce S3 Conflicts)
|
||||
|
||||
```typescript
|
||||
// Writers prefer certain partitions but can use any
|
||||
export class AffinityPartitioner extends HashPartitioner {
|
||||
private preferredPartitions: Set<number>;
|
||||
|
||||
constructor(config: SharedConfig, instanceId: string) {
|
||||
super(config);
|
||||
// Each writer prefers different partition ranges
|
||||
const writerIndex = this.getWriterIndex(instanceId);
|
||||
const partitionsPerWriter = Math.ceil(this.partitionCount / this.writerCount);
|
||||
|
||||
this.preferredPartitions = new Set();
|
||||
const start = writerIndex * partitionsPerWriter;
|
||||
const end = Math.min(start + partitionsPerWriter, this.partitionCount);
|
||||
|
||||
for (let i = start; i < end; i++) {
|
||||
this.preferredPartitions.add(i);
|
||||
}
|
||||
}
|
||||
|
||||
getPartition(vectorId: string): string {
|
||||
const hash = this.xxhash(vectorId);
|
||||
const idealPartition = hash % this.partitionCount;
|
||||
|
||||
// Use ideal if it's in our preferred set
|
||||
if (this.preferredPartitions.has(idealPartition)) {
|
||||
return `vectors/p${idealPartition.toString().padStart(3, '0')}`;
|
||||
}
|
||||
|
||||
// Otherwise use it anyway (correctness > optimization)
|
||||
return `vectors/p${idealPartition.toString().padStart(3, '0')}`;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3.2 Smart Batching for Writers
|
||||
|
||||
```typescript
|
||||
export class BatchWriter {
|
||||
private batch: Map<string, Vector[]> = new Map();
|
||||
private batchSize = 1000;
|
||||
private flushInterval = 5000;
|
||||
|
||||
async add(vector: Vector) {
|
||||
const partition = this.getPartition(vector.id);
|
||||
|
||||
if (!this.batch.has(partition)) {
|
||||
this.batch.set(partition, []);
|
||||
}
|
||||
|
||||
this.batch.get(partition).push(vector);
|
||||
|
||||
// Flush when batch is full
|
||||
if (this.batch.get(partition).length >= this.batchSize) {
|
||||
await this.flushPartition(partition);
|
||||
}
|
||||
}
|
||||
|
||||
private async flushPartition(partition: string) {
|
||||
const vectors = this.batch.get(partition);
|
||||
if (!vectors || vectors.length === 0) return;
|
||||
|
||||
// Single S3 write for entire batch
|
||||
await this.s3.putJSON(
|
||||
`${partition}/batch_${Date.now()}.json`,
|
||||
vectors
|
||||
);
|
||||
|
||||
this.batch.delete(partition);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3.3 Query Optimization for Readers
|
||||
|
||||
```typescript
|
||||
export class OptimizedReader {
|
||||
private partitionStats: Map<string, PartitionStats> = new Map();
|
||||
|
||||
async search(query: number[], k: number = 10) {
|
||||
// Load partition statistics
|
||||
await this.loadPartitionStats();
|
||||
|
||||
// Parallel search with smart pruning
|
||||
const partitions = await this.selectPartitions(query);
|
||||
|
||||
const results = await Promise.all(
|
||||
partitions.map(p => this.searchPartition(p, query, k))
|
||||
);
|
||||
|
||||
// Merge and return top-k
|
||||
return this.mergeResults(results, k);
|
||||
}
|
||||
|
||||
private async selectPartitions(query: number[]) {
|
||||
// For hash partitioning, usually search all
|
||||
// But can optimize based on domain filters or stats
|
||||
return this.getAllPartitions();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Deployment Examples
|
||||
|
||||
### Minimal Configuration
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
services:
|
||||
writer:
|
||||
image: myapp
|
||||
environment:
|
||||
BRAINY_ROLE: writer # Optional - auto-detects if not set
|
||||
|
||||
reader:
|
||||
image: myapp
|
||||
environment:
|
||||
BRAINY_ROLE: reader # Optional - auto-detects if not set
|
||||
scale: 3
|
||||
```
|
||||
|
||||
### Kubernetes
|
||||
|
||||
```yaml
|
||||
# No config needed - auto-detection works!
|
||||
apiVersion: apps/v1
|
||||
kind: Deployment
|
||||
metadata:
|
||||
name: brainy-readers
|
||||
spec:
|
||||
replicas: 10
|
||||
template:
|
||||
spec:
|
||||
containers:
|
||||
- name: app
|
||||
image: myapp
|
||||
# Role auto-detected as reader (multiple replicas)
|
||||
```
|
||||
|
||||
### Application Code
|
||||
|
||||
```typescript
|
||||
// Simplest - full auto mode
|
||||
const brainy = new BrainyData({
|
||||
storage: { type: 's3', bucket: 'my-bucket' },
|
||||
distributed: true // That's it!
|
||||
});
|
||||
|
||||
// With domain hints (optional)
|
||||
await brainy.add(vector, {
|
||||
domain: 'medical', // Helps with organization
|
||||
...metadata
|
||||
});
|
||||
|
||||
// Search everything
|
||||
const results = await brainy.search(queryVector);
|
||||
|
||||
// Or filter by domain
|
||||
const medical = await brainy.search(queryVector, {
|
||||
filter: { domain: 'medical' }
|
||||
});
|
||||
```
|
||||
|
||||
## Summary of Benefits
|
||||
|
||||
### Phase 1 (Days 1-4)
|
||||
- ✅ **Zero-config distributed mode** - Just add `distributed: true`
|
||||
- ✅ **Automatic role detection** - No manual assignment needed
|
||||
- ✅ **Hash partitioning** - Solves multi-writer semantic conflicts
|
||||
- ✅ **Shared configuration** - All instances stay in sync
|
||||
- **Benefit**: 50-70% search performance improvement through parallel readers
|
||||
|
||||
### Phase 2 (Days 5-7)
|
||||
- ✅ **Optimized caching** - Readers cache aggressively, writers batch
|
||||
- ✅ **Domain tagging** - Logical separation without complexity
|
||||
- ✅ **Health monitoring** - Automatic cleanup of dead instances
|
||||
- **Benefit**: Additional 20-30% performance gain
|
||||
|
||||
### Phase 3 (Optional)
|
||||
- ✅ **Partition affinity** - Reduce S3 write conflicts
|
||||
- ✅ **Smart batching** - Fewer S3 operations
|
||||
- ✅ **Query optimization** - Pruning and parallel search
|
||||
- **Benefit**: 10-20% improvement for write-heavy workloads
|
||||
|
||||
## Migration Path
|
||||
|
||||
```typescript
|
||||
// Day 1: Your current code (no changes needed!)
|
||||
const brainy = new BrainyData({
|
||||
storage: { type: 's3', bucket: 'my-bucket' }
|
||||
});
|
||||
|
||||
// Day 4: Enable distributed mode (one line change)
|
||||
const brainy = new BrainyData({
|
||||
storage: { type: 's3', bucket: 'my-bucket' },
|
||||
distributed: true // Everything else is automatic!
|
||||
});
|
||||
|
||||
// That's it! The system handles the rest.

# Proposed Brainy Enhancements for Distributed Operations
|
||||
|
||||
## Executive Summary
|
||||
|
||||
To fully support the distributed deployment scenario with multiple specialized instances sharing S3 storage, Brainy needs several enhancements focused on coordination, consistency, and operational modes.
|
||||
|
||||
## Core Enhancement Areas
|
||||
|
||||
### 1. Instance Role Management
|
||||
|
||||
**Current State**: Brainy operates as a standalone instance without awareness of other instances.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// New distributed configuration options
|
||||
export interface DistributedConfig {
|
||||
role: 'reader' | 'writer' | 'hybrid';
|
||||
instanceId: string;
|
||||
coordinationMethod: 'none' | 's3-polling' | 'websocket' | 'pubsub';
|
||||
consistencyLevel: 'eventual' | 'strong' | 'bounded';
|
||||
conflictResolution: 'last-write-wins' | 'vector-clock' | 'crdt';
|
||||
}
|
||||
|
||||
// Enhanced BrainyData constructor
|
||||
class BrainyData {
|
||||
constructor(config: BrainyConfig & { distributed?: DistributedConfig }) {
|
||||
if (config.distributed) {
|
||||
this.initializeDistributedMode(config.distributed);
|
||||
}
|
||||
}
|
||||
|
||||
private initializeDistributedMode(config: DistributedConfig) {
|
||||
// Set up role-specific behaviors
|
||||
switch(config.role) {
|
||||
case 'reader':
|
||||
this.storage.setReadOnly(true);
|
||||
this.enableAggressiveCaching();
|
||||
this.subscribeToIndexUpdates();
|
||||
break;
|
||||
case 'writer':
|
||||
this.storage.setWriteOnly(true);
|
||||
this.enableWriteBatching();
|
||||
this.publishIndexUpdates();
|
||||
break;
|
||||
case 'hybrid':
|
||||
this.enableCoordinatedAccess();
|
||||
break;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. S3 Coordination Layer
|
||||
|
||||
**Current State**: Direct S3 operations without coordination.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/storage/s3Coordinator.ts
|
||||
export class S3Coordinator {
|
||||
private manifestPath = '_brainy/manifest.json';
|
||||
private lockPrefix = '_brainy/locks/';
|
||||
|
||||
async acquireWriteLock(partition: string): Promise<LockHandle> {
|
||||
const lockKey = `${this.lockPrefix}${partition}`;
|
||||
const lockId = `${this.instanceId}-${Date.now()}`;
|
||||
|
||||
// Use S3's conditional PUT for atomic lock acquisition
|
||||
try {
|
||||
await this.s3.putObject({
|
||||
Bucket: this.bucket,
|
||||
Key: lockKey,
|
||||
Body: JSON.stringify({
|
||||
owner: this.instanceId,
|
||||
acquired: Date.now(),
|
||||
ttl: 30000 // 30 second TTL
|
||||
}),
|
||||
Condition: 'ObjectDoesNotExist'
|
||||
});
|
||||
|
||||
return new LockHandle(lockId, () => this.releaseLock(lockKey));
|
||||
} catch (err) {
|
||||
if (err.code === 'PreconditionFailed') {
|
||||
throw new LockAcquisitionError(`Partition ${partition} is locked`);
|
||||
}
|
||||
throw err;
|
||||
}
|
||||
}
|
||||
|
||||
async updateManifest(update: ManifestUpdate) {
|
||||
// Atomic manifest updates using versioning
|
||||
const manifest = await this.getManifest();
|
||||
manifest.version++;
|
||||
manifest.lastUpdate = Date.now();
|
||||
manifest.updates.push(update);
|
||||
|
||||
await this.s3.putObject({
|
||||
Bucket: this.bucket,
|
||||
Key: this.manifestPath,
|
||||
Body: JSON.stringify(manifest),
|
||||
Metadata: {
|
||||
'version': manifest.version.toString()
|
||||
}
|
||||
});
|
||||
|
||||
// Notify other instances
|
||||
await this.broadcastUpdate(update);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Partition Assignment Strategy
|
||||
|
||||
**Current State**: All instances access all partitions.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/partitioning/distributedPartitioner.ts
|
||||
export class DistributedPartitioner {
|
||||
private assignments: Map<string, Set<string>> = new Map();
|
||||
|
||||
async assignPartitions(instances: Instance[]): Promise<PartitionAssignment> {
|
||||
const writers = instances.filter(i => i.role === 'writer');
|
||||
const partitions = await this.getAllPartitions();
|
||||
|
||||
// Use consistent hashing for stable assignments
|
||||
const ring = new ConsistentHashRing(writers.map(w => w.id));
|
||||
|
||||
const assignment: PartitionAssignment = {};
|
||||
for (const partition of partitions) {
|
||||
const writer = ring.getNode(partition.id);
|
||||
assignment[writer] = assignment[writer] || [];
|
||||
assignment[writer].push(partition.id);
|
||||
}
|
||||
|
||||
// Store assignments in S3 for coordination
|
||||
await this.storeAssignments(assignment);
|
||||
|
||||
return assignment;
|
||||
}
|
||||
|
||||
async getMyPartitions(): Promise<string[]> {
|
||||
const assignments = await this.loadAssignments();
|
||||
return assignments[this.instanceId] || [];
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Write-Ahead Log for Consistency
|
||||
|
||||
**Current State**: Direct writes without transaction log.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/wal/writeAheadLog.ts
|
||||
export class WriteAheadLog {
|
||||
private logPrefix = '_brainy/wal/';
|
||||
|
||||
async logWrite(operation: WriteOperation): Promise<string> {
|
||||
const logEntry = {
|
||||
id: uuidv4(),
|
||||
timestamp: Date.now(),
|
||||
instanceId: this.instanceId,
|
||||
operation: operation,
|
||||
status: 'pending'
|
||||
};
|
||||
|
||||
// Write to WAL first
|
||||
await this.s3.putObject({
|
||||
Bucket: this.bucket,
|
||||
Key: `${this.logPrefix}${logEntry.id}`,
|
||||
Body: JSON.stringify(logEntry)
|
||||
});
|
||||
|
||||
// Then execute operation
|
||||
try {
|
||||
await this.executeOperation(operation);
|
||||
await this.markComplete(logEntry.id);
|
||||
} catch (err) {
|
||||
await this.markFailed(logEntry.id, err);
|
||||
throw err;
|
||||
}
|
||||
|
||||
return logEntry.id;
|
||||
}
|
||||
|
||||
async recoverFromWAL() {
|
||||
// On startup, check for incomplete operations
|
||||
const pendingOps = await this.getPendingOperations();
|
||||
|
||||
for (const op of pendingOps) {
|
||||
if (this.canRecover(op)) {
|
||||
await this.retryOperation(op);
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Operational Modes
|
||||
|
||||
**Current State**: Single operational mode.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/modes/operationalModes.ts
|
||||
export abstract class OperationalMode {
|
||||
abstract canRead(): boolean;
|
||||
abstract canWrite(): boolean;
|
||||
abstract canDelete(): boolean;
|
||||
abstract getCacheStrategy(): CacheStrategy;
|
||||
}
|
||||
|
||||
export class ReadOnlyMode extends OperationalMode {
|
||||
canRead() { return true; }
|
||||
canWrite() { return false; }
|
||||
canDelete() { return false; }
|
||||
|
||||
getCacheStrategy() {
|
||||
return {
|
||||
hotCacheRatio: 0.8, // More memory for cache
|
||||
prefetchAggressive: true,
|
||||
ttl: Infinity // Never expire cache in read-only
|
||||
};
|
||||
}
|
||||
}
|
||||
|
||||
export class WriteOnlyMode extends OperationalMode {
|
||||
canRead() { return false; }
|
||||
canWrite() { return true; }
|
||||
canDelete() { return true; }
|
||||
|
||||
getCacheStrategy() {
|
||||
return {
|
||||
hotCacheRatio: 0.2, // Minimal cache, focus on write buffer
|
||||
writeBuffer: true,
|
||||
batchWrites: true
|
||||
};
|
||||
}
|
||||
}
|
||||
|
||||
export class HybridMode extends OperationalMode {
|
||||
constructor(private coordinator: Coordinator) {}
|
||||
|
||||
canRead() { return true; }
|
||||
canWrite() { return this.coordinator.hasWriteLock(); }
|
||||
canDelete() { return this.coordinator.hasWriteLock(); }
|
||||
|
||||
getCacheStrategy() {
|
||||
return {
|
||||
hotCacheRatio: 0.5,
|
||||
adaptive: true // Adjust based on workload
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 6. Health and Coordination Endpoints
|
||||
|
||||
**Current State**: No built-in health/coordination endpoints.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/api/coordinationAPI.ts
|
||||
export class CoordinationAPI {
|
||||
setupEndpoints(app: Express) {
|
||||
// Health check with role information
|
||||
app.get('/health', async (req, res) => {
|
||||
res.json({
|
||||
status: 'healthy',
|
||||
role: this.config.role,
|
||||
instanceId: this.instanceId,
|
||||
partitions: await this.getAssignedPartitions(),
|
||||
metrics: await this.getMetrics()
|
||||
});
|
||||
});
|
||||
|
||||
// Coordination endpoints
|
||||
app.post('/coordinate/rebalance', async (req, res) => {
|
||||
const result = await this.rebalancePartitions();
|
||||
res.json(result);
|
||||
});
|
||||
|
||||
app.get('/coordinate/assignments', async (req, res) => {
|
||||
const assignments = await this.getPartitionAssignments();
|
||||
res.json(assignments);
|
||||
});
|
||||
|
||||
// Sync endpoint for configuration updates
|
||||
app.post('/sync/config', async (req, res) => {
|
||||
await this.updateConfiguration(req.body);
|
||||
res.json({ status: 'updated' });
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 7. Event-Driven Coordination
|
||||
|
||||
**Current State**: No event system.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/events/distributedEvents.ts
|
||||
export class DistributedEventBus {
|
||||
private subscribers: Map<string, Set<EventHandler>> = new Map();
|
||||
|
||||
async emit(event: BrainyEvent) {
|
||||
// Local handlers
|
||||
const handlers = this.subscribers.get(event.type) || new Set();
|
||||
for (const handler of handlers) {
|
||||
await handler(event);
|
||||
}
|
||||
|
||||
// Remote broadcast (pluggable backends)
|
||||
await this.broadcast(event);
|
||||
}
|
||||
|
||||
async broadcast(event: BrainyEvent) {
|
||||
// S3-based event log (simple, no additional deps)
|
||||
if (this.config.broadcastMethod === 's3') {
|
||||
await this.s3.putObject({
|
||||
Bucket: this.bucket,
|
||||
Key: `_brainy/events/${Date.now()}-${event.type}`,
|
||||
Body: JSON.stringify(event)
|
||||
});
|
||||
}
|
||||
|
||||
// WebSocket broadcast
|
||||
if (this.config.broadcastMethod === 'websocket') {
|
||||
this.ws.broadcast(JSON.stringify(event));
|
||||
}
|
||||
|
||||
// Cloud Pub/Sub
|
||||
if (this.config.broadcastMethod === 'pubsub') {
|
||||
await this.pubsub.topic('brainy-events').publish(event);
|
||||
}
|
||||
}
|
||||
|
||||
subscribe(eventType: string, handler: EventHandler) {
|
||||
if (!this.subscribers.has(eventType)) {
|
||||
this.subscribers.set(eventType, new Set());
|
||||
}
|
||||
this.subscribers.get(eventType).add(handler);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 8. Configuration Synchronization
|
||||
|
||||
**Current State**: Local configuration only.
|
||||
|
||||
**Proposed Enhancement**:
|
||||
```typescript
|
||||
// src/config/distributedConfig.ts
|
||||
export class DistributedConfigManager {
|
||||
private configCache: ConfigCache;
|
||||
private configVersion: number = 0;
|
||||
|
||||
async loadConfig(): Promise<BrainyConfig> {
|
||||
// Try S3 first for shared config
|
||||
try {
|
||||
const s3Config = await this.loadFromS3();
|
||||
this.configVersion = s3Config.version;
|
||||
return this.mergeWithLocal(s3Config);
|
||||
} catch (err) {
|
||||
// Fall back to local config
|
||||
return this.loadLocalConfig();
|
||||
}
|
||||
}
|
||||
|
||||
async watchConfigChanges() {
|
||||
// Poll S3 for config updates
|
||||
setInterval(async () => {
|
||||
const latestVersion = await this.getConfigVersion();
|
||||
if (latestVersion > this.configVersion) {
|
||||
const newConfig = await this.loadFromS3();
|
||||
await this.applyConfigUpdate(newConfig);
|
||||
this.configVersion = latestVersion;
|
||||
}
|
||||
}, 10000); // Check every 10 seconds
|
||||
}
|
||||
|
||||
private async applyConfigUpdate(config: BrainyConfig) {
|
||||
// Hot-reload configuration without restart
|
||||
if (config.caching) {
|
||||
this.cacheManager.updateStrategy(config.caching);
|
||||
}
|
||||
if (config.partitioning) {
|
||||
await this.partitioner.reconfigure(config.partitioning);
|
||||
}
|
||||
// Emit event for other components
|
||||
this.eventBus.emit({
|
||||
type: 'config_updated',
|
||||
payload: config
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Implementation Priority
|
||||
|
||||
### Phase 1: Essential Features (Week 1-2)
|
||||
1. **Operational Modes** - Enable read-only/write-only modes
|
||||
2. **S3 Coordination** - Basic locking and manifest management
|
||||
3. **Configuration Sync** - Shared configuration from S3
|
||||
|
||||
### Phase 2: Coordination (Week 3-4)
|
||||
4. **Partition Assignment** - Distributed partition management
|
||||
5. **Event System** - Basic event broadcasting
|
||||
6. **Health Endpoints** - Monitoring and coordination APIs
|
||||
|
||||
### Phase 3: Advanced Features (Week 5-6)
|
||||
7. **Write-Ahead Log** - Consistency and recovery
|
||||
8. **Advanced Coordination** - WebSocket/Pub-Sub integration
|
||||
9. **Auto-rebalancing** - Dynamic partition redistribution
|
||||
|
||||
## Backwards Compatibility
|
||||
|
||||
All enhancements should be optional and backwards compatible:
|
||||
|
||||
```typescript
|
||||
// Default behavior remains unchanged
|
||||
const brainy = new BrainyData({ /* existing config */ });
|
||||
|
||||
// Opt-in to distributed features
|
||||
const distributedBrainy = new BrainyData({
|
||||
/* existing config */,
|
||||
distributed: {
|
||||
enabled: true,
|
||||
role: 'reader',
|
||||
// ... distributed options
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
- Test each operational mode independently
|
||||
- Mock S3 coordination operations
|
||||
- Test configuration synchronization
|
||||
|
||||
### Integration Tests
|
||||
- Multi-instance coordination tests
|
||||
- Partition assignment and rebalancing
|
||||
- Consistency under concurrent operations
|
||||
|
||||
### Load Tests
|
||||
- Simulate millions of vectors
|
||||
- Test read/write separation at scale
|
||||
- Measure coordination overhead
|
||||
|
||||
## Performance Impact
|
||||
|
||||
Expected performance characteristics:
|
||||
- **Read-only instances**: 10-20% faster due to optimized caching
|
||||
- **Write-only instances**: 30-40% higher throughput with batching
|
||||
- **Coordination overhead**: <100ms for most operations
|
||||
- **Configuration sync**: <1s propagation delay
|
||||
|
||||
## Conclusion
|
||||
|
||||
These enhancements would transform Brainy into a truly distributed vector database system capable of handling large-scale deployments with specialized instances. The modular design ensures that simpler use cases remain unaffected while enabling sophisticated distributed architectures when needed.

# Distributed Brainy Deployment: Multi-Instance S3 Architecture
|
||||
|
||||
## Scenario Overview
|
||||
|
||||
A production deployment with 3 specialized Brainy instances sharing a single S3 bucket as the source of truth:
|
||||
|
||||
1. **Search Instance** (Read-Only): High-performance search across millions of vectors
|
||||
2. **Bluesky Processor** (Write-Only): High-throughput ingestion from Bluesky firehose
|
||||
3. **GitHub Crawler** (Write-Only): Continuous crawling and indexing of GitHub data
|
||||
|
||||
All instances run as Google Cloud Run containers with shared S3 storage.
|
||||
|
||||
## Architecture Design
|
||||
|
||||
### Shared Configuration Strategy
|
||||
|
||||
#### Option 1: Configuration Service (Recommended)
|
||||
```typescript
|
||||
// config-service.ts - Deployed as separate Cloud Run service
|
||||
export class BrainyConfigService {
|
||||
private s3Config = {
|
||||
bucket: 'brainy-vectors-prod',
|
||||
configPath: '_brainy/config.json',
|
||||
lockPath: '_brainy/config.lock'
|
||||
};
|
||||
|
||||
async getSharedConfig(): Promise<BrainyConfig> {
|
||||
// Fetch from S3 with caching
|
||||
return {
|
||||
hnsw: {
|
||||
M: 16,
|
||||
efConstruction: 200,
|
||||
seed: 42, // Critical: same seed for consistent partitioning
|
||||
maxElements: 10000000
|
||||
},
|
||||
partitioning: {
|
||||
strategy: 'semantic',
|
||||
numPartitions: 128, // Must be consistent across instances
|
||||
replicationFactor: 3,
|
||||
hashFunction: 'xxhash' // Deterministic partitioning
|
||||
},
|
||||
storage: {
|
||||
compressionLevel: 6,
|
||||
chunkSize: 1024 * 1024, // 1MB chunks
|
||||
prefixStrategy: 'date-based' // e.g., /2024/01/15/
|
||||
},
|
||||
caching: {
|
||||
hotCacheSize: '2GB',
|
||||
warmCacheSize: '8GB',
|
||||
ttl: 3600
|
||||
}
|
||||
};
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Option 2: S3-Based Config Synchronization
|
||||
Store configuration in S3 with versioning and atomic updates:
|
||||
```
|
||||
s3://brainy-vectors-prod/
|
||||
_brainy/
|
||||
config.json # Shared configuration
|
||||
schema.json # Vector schema definition
|
||||
partitions.json # Partition mapping
|
||||
instances/
|
||||
search-001.json # Instance-specific overrides
|
||||
bluesky-001.json
|
||||
github-001.json
|
||||
```
|
||||
|
||||
### Instance-Specific Configurations
|
||||
|
||||
#### 1. Search Instance (Read-Only)
|
||||
```typescript
|
||||
const searchConfig = {
|
||||
...sharedConfig,
|
||||
mode: 'read-only',
|
||||
caching: {
|
||||
hotCacheSize: '8GB', // Maximize cache for search
|
||||
warmCacheSize: '32GB',
|
||||
prefetchStrategy: 'aggressive',
|
||||
bloomFilters: true // Fast negative lookups
|
||||
},
|
||||
hnsw: {
|
||||
...sharedConfig.hnsw,
|
||||
efSearch: 100, // Higher for better recall
|
||||
useMmap: true // Memory-mapped files for large indices
|
||||
},
|
||||
s3: {
|
||||
readConcurrency: 20, // High parallelism for reads
|
||||
useTransferAcceleration: true,
|
||||
cacheHeaders: true
|
||||
},
|
||||
monitoring: {
|
||||
metrics: ['latency', 'recall', 'cache_hit_rate']
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
#### 2. Bluesky Processor (Write-Only)
|
||||
```typescript
|
||||
const blueksyConfig = {
|
||||
...sharedConfig,
|
||||
mode: 'write-only',
|
||||
batching: {
|
||||
size: 10000, // Large batches for throughput
|
||||
flushInterval: 5000, // 5 seconds
|
||||
parallelWrites: 4
|
||||
},
|
||||
deduplication: {
|
||||
enabled: true,
|
||||
bloomFilter: true,
|
||||
windowSize: 1000000 // Check last 1M entries
|
||||
},
|
||||
s3: {
|
||||
writeConcurrency: 10,
|
||||
multipartThreshold: 50 * 1024 * 1024, // 50MB
|
||||
useServerSideEncryption: true
|
||||
},
|
||||
indexing: {
|
||||
async: true, // Don't wait for index updates
|
||||
batchIndexUpdates: true
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
#### 3. GitHub Crawler (Write-Only)
|
||||
```typescript
|
||||
const githubConfig = {
|
||||
...sharedConfig,
|
||||
mode: 'write-only',
|
||||
rateLimit: {
|
||||
requestsPerSecond: 10, // Respect API limits
|
||||
burstSize: 20
|
||||
},
|
||||
batching: {
|
||||
size: 1000, // Smaller batches, continuous flow
|
||||
flushInterval: 10000 // 10 seconds
|
||||
},
|
||||
embedding: {
|
||||
model: 'text-embedding-3-small',
|
||||
batchSize: 100,
|
||||
cacheEmbeddings: true
|
||||
},
|
||||
s3: {
|
||||
writeConcurrency: 5,
|
||||
retryStrategy: 'exponential'
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
## Synchronization Mechanisms
|
||||
|
||||
### 1. Partition Coordinator Service
|
||||
Deploy a lightweight coordinator that manages partition assignments:
|
||||
|
||||
```typescript
|
||||
class PartitionCoordinator {
|
||||
private websocket: WebSocketServer;
|
||||
|
||||
async assignPartition(instanceId: string, mode: 'read' | 'write') {
|
||||
if (mode === 'write') {
|
||||
// Ensure no partition is assigned to multiple writers
|
||||
return this.getExclusivePartition(instanceId);
|
||||
} else {
|
||||
// Readers can access all partitions
|
||||
return 'all';
|
||||
}
|
||||
}
|
||||
|
||||
async rebalance() {
|
||||
// Triggered when instances join/leave
|
||||
// Ensures even distribution of write load
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Event Broadcasting via Pub/Sub
|
||||
Use Google Cloud Pub/Sub for coordination:
|
||||
|
||||
```typescript
|
||||
interface BrainyEvent {
|
||||
type: 'partition_created' | 'index_updated' | 'config_changed';
|
||||
timestamp: number;
|
||||
payload: any;
|
||||
}
|
||||
|
||||
// Writers publish events
|
||||
await pubsub.topic('brainy-events').publish({
|
||||
type: 'partition_created',
|
||||
payload: { partitionId: 'p-123', vectorCount: 50000 }
|
||||
});
|
||||
|
||||
// Readers subscribe and update local state
|
||||
subscription.on('message', (message) => {
|
||||
if (message.type === 'index_updated') {
|
||||
await this.refreshLocalIndex(message.payload.partitionId);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Performance Optimizations
|
||||
|
||||
### 1. Write Path Optimization
|
||||
```typescript
|
||||
// Parallel partition writes
|
||||
class PartitionedWriter {
|
||||
async write(vectors: Vector[]) {
|
||||
const partitioned = this.partitionVectors(vectors);
|
||||
|
||||
await Promise.all(
|
||||
Object.entries(partitioned).map(([partitionId, vecs]) =>
|
||||
this.writeToPartition(partitionId, vecs)
|
||||
)
|
||||
);
|
||||
}
|
||||
|
||||
private partitionVectors(vectors: Vector[]) {
|
||||
// Use consistent hash to determine partition
|
||||
return vectors.reduce((acc, vec) => {
|
||||
const partition = hashToPartition(vec.id);
|
||||
acc[partition] = acc[partition] || [];
|
||||
acc[partition].push(vec);
|
||||
return acc;
|
||||
}, {});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Read Path Optimization
|
||||
```typescript
|
||||
// Distributed search with result aggregation
|
||||
class DistributedSearch {
|
||||
async search(query: Vector, k: number) {
|
||||
// Identify relevant partitions using routing table
|
||||
const partitions = await this.getRelevantPartitions(query);
|
||||
|
||||
// Parallel search across partitions
|
||||
const results = await Promise.all(
|
||||
partitions.map(p => this.searchPartition(p, query, k * 2))
|
||||
);
|
||||
|
||||
// Merge and re-rank results
|
||||
return this.mergeResults(results, k);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. S3 Optimization Strategies
|
||||
```typescript
|
||||
const s3Optimizations = {
|
||||
// Use S3 Transfer Acceleration for cross-region
|
||||
transferAcceleration: true,
|
||||
|
||||
// Intelligent prefixing for parallel reads
|
||||
prefixSharding: {
|
||||
enabled: true,
|
||||
shardCount: 16, // Distribute across 16 prefixes
|
||||
strategy: 'hash' // or 'round-robin'
|
||||
},
|
||||
|
||||
// Batch operations
|
||||
batchOperations: {
|
||||
getObject: 100, // Batch up to 100 GETs
|
||||
putObject: 50 // Batch up to 50 PUTs
|
||||
},
|
||||
|
||||
// Caching strategy
|
||||
caching: {
|
||||
cloudFront: true, // Use CDN for read-heavy workloads
|
||||
s3CacheControl: 'max-age=3600'
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
## Suggested Brainy Enhancements
|
||||
|
||||
### 1. Native Distributed Mode
|
||||
```typescript
|
||||
// Proposed API
|
||||
const brainy = new BrainyData({
|
||||
distributed: {
|
||||
mode: 'cluster',
|
||||
role: 'writer' | 'reader' | 'hybrid',
|
||||
coordinator: 'redis://coordinator:6379',
|
||||
instanceId: process.env.INSTANCE_ID
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### 2. S3 Lock Manager
|
||||
```typescript
|
||||
class S3LockManager {
|
||||
async acquireLock(resource: string, ttl: number) {
|
||||
// Use S3 conditional puts for distributed locking
|
||||
const lockKey = `_locks/${resource}`;
|
||||
const lockValue = `${this.instanceId}-${Date.now()}`;
|
||||
|
||||
try {
|
||||
await s3.putObject({
|
||||
Bucket: this.bucket,
|
||||
Key: lockKey,
|
||||
Body: lockValue,
|
||||
Metadata: { ttl: ttl.toString() },
|
||||
Condition: 'ObjectDoesNotExist'
|
||||
});
|
||||
return true;
|
||||
} catch (err) {
|
||||
if (err.code === 'PreconditionFailed') {
|
||||
return false; // Lock already held
|
||||
}
|
||||
throw err;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Partition Discovery Service
|
||||
```typescript
|
||||
class PartitionDiscovery {
|
||||
private cache = new Map();
|
||||
|
||||
async discoverPartitions(): Promise<Partition[]> {
|
||||
// List S3 prefixes to discover partitions
|
||||
const result = await s3.listObjectsV2({
|
||||
Bucket: this.bucket,
|
||||
Prefix: 'partitions/',
|
||||
Delimiter: '/'
|
||||
});
|
||||
|
||||
return result.CommonPrefixes.map(prefix => ({
|
||||
id: prefix.Prefix.split('/')[1],
|
||||
metadata: await this.getPartitionMetadata(prefix.Prefix)
|
||||
}));
|
||||
}
|
||||
|
||||
subscribeToChanges(callback: (event: PartitionEvent) => void) {
|
||||
// Watch S3 events or use SNS/EventBridge
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Consistency Manager
|
||||
```typescript
|
||||
class ConsistencyManager {
|
||||
async ensureConsistency() {
|
||||
// Periodic consistency checks
|
||||
const tasks = [
|
||||
this.verifyPartitionIntegrity(),
|
||||
this.checkIndexConsistency(),
|
||||
this.validateConfiguration()
|
||||
];
|
||||
|
||||
const results = await Promise.all(tasks);
|
||||
|
||||
if (results.some(r => !r.valid)) {
|
||||
await this.triggerRepair();
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Deployment Configuration
|
||||
|

### Environment Variables
|
||||
```bash
|
||||
# Common to all instances
|
||||
BRAINY_S3_BUCKET=brainy-vectors-prod
|
||||
BRAINY_S3_REGION=us-central1
|
||||
BRAINY_CONFIG_SOURCE=s3
|
||||
BRAINY_CONFIG_PATH=_brainy/config.json
|
||||
|
||||
# Instance-specific
|
||||
BRAINY_INSTANCE_ID=${K_SERVICE}-${K_REVISION}
|
||||
BRAINY_ROLE=search|bluesky|github
|
||||
BRAINY_MODE=read-only|write-only
|
||||
```
|
||||
|
||||
## Monitoring and Operations
|
||||
|
||||
### Key Metrics to Track
|
||||
1. **Search Instance**
|
||||
- Query latency (p50, p95, p99)
|
||||
- Cache hit ratio
|
||||
- Concurrent searches
|
||||
- S3 GET requests/sec
|
||||
|
||||
2. **Write Instances**
|
||||
- Ingestion rate (vectors/sec)
|
||||
- Batch size and latency
|
||||
- S3 PUT requests/sec
|
||||
- Partition distribution
|
||||
|
||||
3. **System-Wide**
|
||||
- Total vector count
|
||||
- Partition count and size distribution
|
||||
- S3 storage usage and costs
|
||||
- Cross-instance consistency lag
|
||||
|
||||
### Health Checks
|
||||
```typescript
|
||||
app.get('/health', async (req, res) => {
|
||||
const health = {
|
||||
instance: process.env.BRAINY_INSTANCE_ID,
|
||||
role: process.env.BRAINY_ROLE,
|
||||
status: 'healthy',
|
||||
checks: {
|
||||
s3_connectivity: await checkS3(),
|
||||
config_loaded: await checkConfig(),
|
||||
partition_access: await checkPartitions(),
|
||||
memory_usage: process.memoryUsage()
|
||||
}
|
||||
};
|
||||
|
||||
res.json(health);
|
||||
});
|
||||
```
|
||||
|
||||
## Cost Optimization
|
||||
|
||||
1. **S3 Intelligent Tiering**: Automatically move cold partitions to cheaper storage classes
|
||||
2. **Request Batching**: Minimize S3 API calls through batching
|
||||
3. **CDN for Reads**: Use Cloud CDN for frequently accessed partitions
|
||||
4. **Lifecycle Policies**: Auto-delete old snapshots and temporary data
|
||||
5. **Reserved Capacity**: Use committed use discounts for Cloud Run
|
||||
|
||||
## Implementation Timeline
|
||||
|
||||
### Phase 1: Basic Setup (Week 1)
|
||||
- Deploy 3 instances with shared S3 bucket
|
||||
- Implement basic configuration synchronization
|
||||
- Set up monitoring
|
||||
|
||||
### Phase 2: Optimization (Week 2-3)

|
||||
|
||||
## Conclusion
|
||||
|
||||
This architecture provides a scalable, distributed Brainy deployment that can handle millions of vectors with specialized instances for different workloads. The key is maintaining consistency through shared configuration and coordination while optimizing each instance for its specific role.

## Overview
|
||||
|
||||
Brainy's distributed mode enables you to scale your vector database across multiple instances, each optimized for specific workloads. This guide covers everything you need to know to deploy and manage Brainy at scale.
|
||||
|
||||
### Key Benefits
|
||||
|
||||
- **Horizontal Scaling**: Add readers for query performance, writers for ingestion throughput
|
||||
- **Zero Coordination Overhead**: Simple shared JSON config in S3
|
||||
- **Automatic Optimization**: Each role self-optimizes for its workload
|
||||
- **Multi-Domain Support**: Handle different data types without conflicts
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Basic Setup
|
||||
|
||||
Distributed mode requires explicit role configuration for safety:
|
||||
|
||||
```javascript
|
||||
import { createAutoBrainy } from 'brainy'
|
||||
|
||||
// Option 1: Environment variable (recommended for production)
|
||||
process.env.BRAINY_ROLE = 'writer' // or 'reader' or 'hybrid'
|
||||
const brainy = createAutoBrainy({
|
||||
storage: {
|
||||
type: 's3',
|
||||
bucket: 'my-bucket',
|
||||
region: 'us-east-1',
|
||||
accessKeyId: process.env.AWS_ACCESS_KEY_ID,
|
||||
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
|
||||
},
|
||||
distributed: true
|
||||
})
|
||||
|
||||
// Option 2: Explicit configuration
|
||||
const brainy = createAutoBrainy({
|
||||
storage: { /* s3 config */ },
|
||||
distributed: {
|
||||
role: 'writer' // Must specify role
|
||||
}
|
||||
})
|
||||
|
||||
// Option 3: Inferred from read/write mode
|
||||
const brainy = createAutoBrainy({
|
||||
storage: { /* s3 config */ },
|
||||
writeOnly: true, // Role inferred as 'writer'
|
||||
distributed: true
|
||||
})
|
||||
|
||||
await brainy.init()
|
||||
```
|
||||
|
||||
### 2. Understanding Roles
|
||||
|
||||
Roles must be explicitly configured for each instance:
|
||||
|
||||
| Role | Purpose | Optimizations | When to Use |
|
||||
|------|---------|---------------|-------------|
|
||||
| **Writer** | Data ingestion | Write batching, minimal cache | ETL pipelines, data import |
|
||||
| **Reader** | Query serving | Aggressive caching, prefetching | API servers, search services |
|
||||
| **Hybrid** | Both operations | Adaptive caching | Small deployments, development |
|
||||
|
||||
### 3. Role Configuration Methods
|
||||
|
||||
```javascript
|
||||
// Priority order for role determination:
|
||||
// 1. BRAINY_ROLE environment variable (highest priority)
|
||||
// 2. Explicit role in distributed config
|
||||
// 3. Inferred from readOnly/writeOnly mode
|
||||
// 4. ERROR - role must be explicitly set
|
||||
|
||||
// Examples:
|
||||
// Environment variable (production recommended)
|
||||
BRAINY_ROLE=writer node app.js
|
||||
|
||||
// Explicit in code
|
||||
distributed: { role: 'reader' }
|
||||
|
||||
// Inferred from mode
|
||||
writeOnly: true // becomes 'writer'
|
||||
readOnly: true // becomes 'reader'
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Basic Configuration
|
||||
|
||||
```javascript
|
||||
const brainy = createAutoBrainy({
|
||||
storage: { /* S3 config */ },
|
||||
distributed: {
|
||||
enabled: true, // Enable distributed mode
|
||||
role: 'reader', // Optional: explicit role
|
||||
instanceId: 'reader-01', // Optional: custom ID
|
||||
configPath: '_brainy/config.json', // Config location
|
||||
heartbeatInterval: 30000, // Health check interval
|
||||
instanceTimeout: 60000 // Dead instance timeout
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Environment Variables
|
||||
|
||||
```bash
|
||||
# Set role via environment
|
||||
export BRAINY_ROLE=writer
|
||||
|
||||
# Custom instance ID
|
||||
export BRAINY_INSTANCE_ID=prod-writer-01
|
||||
|
||||
# Service endpoint for health checks
|
||||
export SERVICE_ENDPOINT=http://writer-01:3000
|
||||
```
|
||||
|
||||
### Shared Configuration Structure
|
||||
|
||||
The shared config file (`_brainy/config.json`) in S3:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": 1,
|
||||
"updated": "2024-01-15T10:30:00Z",
|
||||
"settings": {
|
||||
"partitionStrategy": "hash",
|
||||
"partitionCount": 100,
|
||||
"embeddingModel": "text-embedding-ada-002",
|
||||
"dimensions": 1536,
|
||||
"distanceMetric": "cosine"
|
||||
},
|
||||
"instances": {
|
||||
"writer-01": {
|
||||
"role": "writer",
|
||||
"status": "active",
|
||||
"lastHeartbeat": "2024-01-15T10:29:50Z",
|
||||
"metrics": {
|
||||
"vectorCount": 1000000,
|
||||
"cacheHitRate": 0.2,
|
||||
"memoryUsage": 512000000
|
||||
}
|
||||
},
|
||||
"reader-01": {
|
||||
"role": "reader",
|
||||
"status": "active",
|
||||
"lastHeartbeat": "2024-01-15T10:29:55Z",
|
||||
"metrics": {
|
||||
"vectorCount": 1000000,
|
||||
"cacheHitRate": 0.95,
|
||||
"memoryUsage": 1024000000
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Deployment Patterns
|
||||
|
||||
### Pattern 1: Simple Read/Write Split
|
||||
|
||||
Best for: Most applications with clear ingestion vs query workloads
|
||||
|
||||
```yaml
|
||||
# docker-compose.yml
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
writer:
|
||||
image: myapp:latest
|
||||
environment:
|
||||
BRAINY_ROLE: writer
|
||||
AWS_ACCESS_KEY_ID: ${AWS_ACCESS_KEY_ID}
|
||||
AWS_SECRET_ACCESS_KEY: ${AWS_SECRET_ACCESS_KEY}
|
||||
deploy:
|
||||
replicas: 1 # Usually one writer
|
||||
|
||||
reader:
|
||||
image: myapp:latest
|
||||
environment:
|
||||
BRAINY_ROLE: reader
|
||||
AWS_ACCESS_KEY_ID: ${AWS_ACCESS_KEY_ID}
|
||||
AWS_SECRET_ACCESS_KEY: ${AWS_SECRET_ACCESS_KEY}
|
||||
deploy:
|
||||
replicas: 5 # Scale readers as needed
|
||||
```
|
||||
|
||||
### Pattern 2: Multi-Domain Ingestion
|
||||
|
||||
Best for: Multiple data sources with different schemas
|
||||
|
||||
```javascript
|
||||
// Medical data writer
|
||||
const medicalWriter = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: {
|
||||
role: 'writer',
|
||||
instanceId: 'medical-writer'
|
||||
}
|
||||
})
|
||||
|
||||
// Legal data writer
|
||||
const legalWriter = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: {
|
||||
role: 'writer',
|
||||
instanceId: 'legal-writer'
|
||||
}
|
||||
})
|
||||
|
||||
// Unified reader for all domains
|
||||
const reader = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: { role: 'reader' }
|
||||
})
|
||||
```
|
||||
|
||||
### Pattern 3: Lambda + ECS Hybrid
|
||||
|
||||
Best for: Serverless search with persistent ingestion
|
||||
|
||||
```javascript
|
||||
// Lambda function (configure as reader)
|
||||
export const handler = async (event) => {
|
||||
const brainy = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: { role: 'reader' } // Explicit role required
|
||||
// OR use readOnly mode:
|
||||
// readOnly: true,
|
||||
// distributed: true
|
||||
})
|
||||
|
||||
const results = await brainy.search(event.query, 10)
|
||||
return { statusCode: 200, body: JSON.stringify(results) }
|
||||
}
|
||||
|
||||
// ECS task (writer)
|
||||
const writer = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: { role: 'writer' }
|
||||
// OR use writeOnly mode:
|
||||
// writeOnly: true,
|
||||
// distributed: true
|
||||
})
|
||||
```
|
||||
|
||||
### Pattern 4: Kubernetes StatefulSet + Deployment
|
||||
|
||||
```yaml
|
||||
# Writer StatefulSet (persistent identity)
|
||||
apiVersion: apps/v1
|
||||
kind: StatefulSet
|
||||
metadata:
|
||||
name: brainy-writer
|
||||
spec:
|
||||
replicas: 1
|
||||
template:
|
||||
spec:
|
||||
containers:
|
||||
- name: writer
|
||||
env:
|
||||
- name: BRAINY_ROLE
|
||||
value: writer
|
||||
- name: BRAINY_INSTANCE_ID
|
||||
valueFrom:
|
||||
fieldRef:
|
||||
fieldPath: metadata.name
|
||||
|
||||

```
|
||||
|
||||
## Domain Management
|
||||
|
||||
### Automatic Domain Detection
|
||||
|
||||
Brainy automatically detects data domains based on content:
|
||||
|
||||
```javascript
|
||||
// These are automatically tagged with appropriate domains
|
||||
await brainy.add({
|
||||
symptoms: "headache",
|
||||
diagnosis: "migraine"
|
||||
}) // Tagged as 'medical'
|
||||
|
||||
await brainy.add({
|
||||
contract: "lease agreement",
|
||||
parties: ["John", "Jane"]
|
||||
}) // Tagged as 'legal'
|
||||
|
||||
await brainy.add({
|
||||
price: 99.99,
|
||||
sku: "PROD-123"
|
||||
}) // Tagged as 'product'
|
||||
```
|
||||
|
||||
### Custom Domain Patterns
|
||||
|
||||
```javascript
|
||||
import { DomainDetector } from 'brainy/distributed'
|
||||
|
||||
const detector = new DomainDetector()
|
||||
|
||||
// Add custom domain pattern
|
||||
detector.addCustomPattern({
|
||||
domain: 'automotive',
|
||||
patterns: {
|
||||
fields: ['make', 'model', 'year', 'vin'],
|
||||
keywords: ['car', 'vehicle', 'automobile', 'engine'],
|
||||
regex: /\b[A-Z0-9]{17}\b/ // VIN pattern
|
||||
},
|
||||
priority: 1
|
||||
})
|
||||
```
|
||||
|
||||
### Searching by Domain
|
||||
|
||||
```javascript
|
||||
// Search all domains
|
||||
const allResults = await brainy.search("treatment options", 10)
|
||||
|
||||
// Search specific domain
|
||||
const medicalOnly = await brainy.search("treatment options", 10, {
|
||||
filter: { domain: 'medical' }
|
||||
})
|
||||
|
||||
// Multiple domain search
|
||||
const results = await Promise.all([
|
||||
brainy.search(query, 5, { filter: { domain: 'medical' } }),
|
||||
brainy.search(query, 5, { filter: { domain: 'legal' } })
|
||||
])
|
||||
```
|
||||
|
||||
## Health Monitoring
|
||||
|
||||
### Getting Health Status
|
||||
|
||||
```javascript
|
||||
const health = brainy.getHealthStatus()
|
||||
console.log(health)
|
||||
// {
|
||||
// status: 'healthy',
|
||||
// instanceId: 'reader-01',
|
||||
// role: 'reader',
|
||||
// uptime: 3600,
|
||||
// metrics: {
|
||||
// vectorCount: 1000000,
|
||||
// cacheHitRate: 0.95,
|
||||
// memoryUsageMB: 1024,
|
||||
// cpuUsagePercent: 45,
|
||||
// requestsPerSecond: 150,
|
||||
// averageLatencyMs: 25,
|
||||
// errorRate: 0.001
|
||||
// },
|
||||
// warnings: ['High memory usage detected']
|
||||
// }
|
||||
```
|
||||
|
||||
### Health Check Endpoint
|
||||
|
||||
```javascript
|
||||
// Express.js health endpoint
|
||||
app.get('/health', (req, res) => {
|
||||
const health = brainy.getHealthStatus()
|
||||
|
||||
// Return appropriate HTTP status
|
||||
const httpStatus = health.status === 'healthy' ? 200 :
|
||||
health.status === 'degraded' ? 503 : 500
|
||||
|
||||
res.status(httpStatus).json(health)
|
||||
})
|
||||
```
|
||||
|
||||
### Monitoring Dashboard
|
||||
|
||||
```javascript
|
||||
// Collect metrics for monitoring
|
||||
setInterval(async () => {
|
||||
const health = brainy.getHealthStatus()
|
||||
|
||||
// Send to monitoring service
|
||||
await prometheus.gauge('brainy_vector_count', health.metrics.vectorCount)
|
||||
await prometheus.gauge('brainy_cache_hit_rate', health.metrics.cacheHitRate)
|
||||
await prometheus.gauge('brainy_memory_usage', health.metrics.memoryUsageMB)
|
||||
await prometheus.gauge('brainy_rps', health.metrics.requestsPerSecond)
|
||||
}, 30000)
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Reader Optimization
|
||||
|
||||
```javascript
|
||||
// Readers benefit from aggressive caching
|
||||
const reader = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: { role: 'reader' },
|
||||
cache: {
|
||||
hotCacheMaxSize: 50000, // Large cache for frequent items
|
||||
hotCacheEvictionThreshold: 0.9, // Keep cache full
|
||||
warmCacheTTL: 3600000, // 1 hour TTL
|
||||
readOnlyMode: {
|
||||
prefetchStrategy: 'aggressive' // Prefetch related vectors
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Writer Optimization
|
||||
|
||||
```javascript
|
||||
// Writers benefit from batching
|
||||
const writer = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: { role: 'writer' },
|
||||
cache: {
|
||||
hotCacheMaxSize: 5000, // Small cache
|
||||
batchSize: 1000, // Large batch writes
|
||||
autoTune: false // Consistent write performance
|
||||
}
|
||||
})
|
||||
|
||||
// Batch insertions for better performance
|
||||
const batch = []
|
||||
for (const item of items) {
|
||||
batch.push(writer.add(item, metadata))
|
||||
|
||||
if (batch.length >= 100) {
|
||||
await Promise.all(batch)
|
||||
batch.length = 0
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Network Optimization
|
||||
|
||||
```javascript
|
||||
// Use connection pooling for S3
|
||||
const s3Config = {
|
||||
type: 's3',
|
||||
bucket: 'my-bucket',
|
||||
maxRetries: 3,
|
||||
httpOptions: {
|
||||
agent: new https.Agent({
|
||||
keepAlive: true,
|
||||
maxSockets: 50
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### 1. Role Conflicts
|
||||
|
||||
**Problem**: Multiple instances trying to be writers
|
||||
|
||||
**Solution**: Explicitly set roles
|
||||
```javascript
|
||||
// Use environment variables
|
||||
BRAINY_ROLE=writer node writer.js
|
||||
BRAINY_ROLE=reader node reader.js
|
||||
```
|
||||
|
||||
#### 2. Stale Instances
|
||||
|
||||
**Problem**: Dead instances not being cleaned up
|
||||
|
||||
**Solution**: Check heartbeat settings
|
||||
```javascript
|
||||
const brainy = createAutoBrainy({
|
||||
distributed: {
|
||||
heartbeatInterval: 15000, // More frequent heartbeats
|
||||
instanceTimeout: 45000 // Shorter timeout
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
#### 3. Configuration Conflicts
|
||||
|
||||
**Problem**: Instances have incompatible settings
|
||||
|
||||
**Solution**: Check the shared config
|
||||
```bash
|
||||
# Download and inspect config
|
||||
aws s3 cp s3://my-bucket/_brainy/config.json ./config.json
|
||||
cat config.json
|
||||
|
||||
# Fix and upload if needed
|
||||
aws s3 cp ./config.json s3://my-bucket/_brainy/config.json
|
||||
```
|
||||
|
||||
#### 4. Performance Issues
|
||||
|
||||
**Problem**: Slow searches in distributed mode
|
||||
|
||||
**Solution**: Check role distribution
|
||||
```javascript
|
||||
// Ensure you have enough readers
|
||||
const config = await brainy.getDistributedConfig()
|
||||
const readers = Object.values(config.instances)
|
||||
.filter(i => i.role === 'reader' && i.status === 'active')
|
||||
|
||||
console.log(`Active readers: ${readers.length}`)
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
|
||||
```javascript
|
||||
// Enable verbose logging
|
||||
const brainy = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: true,
|
||||
logging: { verbose: true }
|
||||
})
|
||||
|
||||
// Logs will show:
|
||||
// - Role detection process
|
||||
// - Configuration updates
|
||||
// - Partition assignments
|
||||
// - Domain detection
|
||||
// - Health check results
|
||||
```
|
||||
|
||||
## Migration Guide
|
||||
|
||||
### From Single Instance to Distributed
|
||||
|
||||
#### Step 1: Prepare S3 Storage
|
||||
|
||||
```javascript
|
||||
// Before: Local or single S3 instance
|
||||
const brainy = createAutoBrainy({
|
||||
storage: { type: 'opfs' } // or single S3
|
||||
})
|
||||
|
||||
// After: S3 with distributed config
|
||||
const brainy = createAutoBrainy({
|
||||
storage: {
|
||||
type: 's3',
|
||||
bucket: 'my-bucket',
|
||||
region: 'us-east-1',
|
||||
accessKeyId: process.env.AWS_ACCESS_KEY_ID,
|
||||
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
|
||||
},
|
||||
distributed: true
|
||||
})
|
||||
```
|
||||
|
||||
#### Step 2: Migrate Data
|
||||
|
||||
```javascript
|
||||
// Export from old instance
|
||||
const allData = await oldBrainy.exportAll()
|
||||
|
||||
// Import to new distributed instance
|
||||
const writer = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: { role: 'writer' }
|
||||
})
|
||||
|
||||
for (const item of allData) {
|
||||
await writer.add(item.vector, item.metadata, { id: item.id })
|
||||
}
|
||||
```
|
||||
|
||||
#### Step 3: Update Application Code
|
||||
|
||||
```javascript
|
||||
// Add distributed initialization
|
||||
const brainy = createAutoBrainy({
|
||||
storage: s3Config,
|
||||
distributed: true
|
||||
})
|
||||
|
||||
// Add cleanup on shutdown
|
||||
process.on('SIGTERM', async () => {
|
||||
await brainy.cleanup()
|
||||
process.exit(0)
|
||||
})
|
||||
```
|
||||
|
||||
#### Step 4: Deploy Readers
|
||||
|
||||
```yaml
|
||||
# Scale out readers gradually
|
||||
kubectl scale deployment brainy-readers --replicas=2
|
||||
# Monitor performance
|
||||
kubectl scale deployment brainy-readers --replicas=5
|
||||
# Continue scaling as needed
|
||||
kubectl scale deployment brainy-readers --replicas=10
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Start Small**: Begin with 1 writer and 2-3 readers
|
||||
2. **Monitor Metrics**: Watch cache hit rates and latency
|
||||
3. **Scale Gradually**: Add instances based on actual load
|
||||
4. **Use Health Checks**: Integrate with load balancers
|
||||
5. **Clean Shutdown**: Always call `cleanup()` on shutdown
|
||||
6. **Regular Backups**: Backup S3 bucket regularly
|
||||
|
||||
## Advanced Topics
|
||||
|
||||
### Custom Partitioning
|
||||
|
||||
```javascript
|
||||
// Override default hash partitioning
|
||||
class CustomPartitioner extends HashPartitioner {
|
||||
getPartition(vectorId) {
|
||||
// Custom logic for partition assignment
|
||||
if (vectorId.startsWith('priority-')) {
|
||||
return 'vectors/p000' // Hot partition
|
||||
}
|
||||
return super.getPartition(vectorId)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Multi-Region Deployment
|
||||
|
||||
```javascript
|
||||
// Region-specific readers
|
||||
const usReader = createAutoBrainy({
|
||||
storage: {
|
||||
type: 's3',
|
||||
bucket: 'my-bucket',
|
||||
region: 'us-east-1'
|
||||
},
|
||||
distributed: {
|
||||
role: 'reader',
|
||||
instanceId: 'us-reader-01'
|
||||
}
|
||||
})
|
||||
|
||||
const euReader = createAutoBrainy({
|
||||
storage: {
|
||||
type: 's3',
|
||||
bucket: 'my-bucket-eu',
|
||||
region: 'eu-west-1'
|
||||
},
|
||||
distributed: {
|
||||
role: 'reader',
|
||||
instanceId: 'eu-reader-01'
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Hybrid Cloud Deployment
|
||||
|
||||
```javascript
|
||||
// On-premise writer
|
||||
const onPremWriter = createAutoBrainy({
|
||||
storage: {
|
||||
type: 'customS3',
|
||||
endpoint: 'https://minio.internal:9000',
|
||||
bucket: 'brainy-data'
|
||||
},
|
||||
distributed: { role: 'writer' }
|
||||
})
|
||||
|
||||
// Cloud readers
|
||||
const cloudReader = createAutoBrainy({
|
||||
storage: {
|
||||
type: 's3',
|
||||
bucket: 'brainy-data-replicated'
|
||||
},
|
||||
distributed: { role: 'reader' }
|
||||
})
|
||||
```
|
||||
|
||||
## Conclusion
|
||||
|
||||
Brainy's distributed mode provides a simple yet powerful way to scale your vector database. With automatic role detection, zero-coordination overhead, and built-in optimizations, you can focus on building your application while Brainy handles the complexity of distributed systems.

|
||||
|
||||
## 🎯 Choose Your Scenario
|
||||
|
||||
### Scenario 1: Development & Testing
|
||||
```typescript
|
||||
import { createAutoBrainy } from '@soulcraft/brainy'
|
||||
|
||||
// Perfect for development - uses memory storage
|
||||
const brainy = createAutoBrainy()
|
||||
|
||||
// Add test data
|
||||
await brainy.addVector({ id: '1', vector: [0.1, 0.2, 0.3] })
|
||||
await brainy.addVector({ id: '2', vector: [0.4, 0.5, 0.6] })
|
||||
|
||||
// Search
|
||||
const results = await brainy.search([0.1, 0.2, 0.3], 5)
|
||||
```
|
||||
|
||||
### Scenario 2: Production with Persistence
|
||||
```typescript
|
||||
import { createAutoBrainy } from '@soulcraft/brainy'
|
||||
|
||||
// Auto-detects AWS credentials from environment variables
|
||||
const brainy = createAutoBrainy({
|
||||
bucketName: 'my-vector-storage'
|
||||
})
|
||||
|
||||
// Data persists in S3 - survives restarts
|
||||
await brainy.addVector({ id: '1', vector: [0.1, 0.2, 0.3] })
|
||||
```
|
||||
|
||||
### Scenario 3: Scale-Specific Setup
|
||||
```typescript
|
||||
import { createQuickBrainy } from '@soulcraft/brainy'
|
||||
|
||||
// Choose your scale: 'small', 'medium', 'large', 'enterprise'
|
||||
const brainy = await createQuickBrainy('large', {
|
||||
bucketName: 'my-big-vector-db'
|
||||
})
|
||||
|
||||
// System auto-configures for 1M+ vectors
|
||||
```
|
||||
|
||||
### Scenario 4: Text-Based Semantic Search
|
||||
```typescript
|
||||
import { createAutoBrainy } from '@soulcraft/brainy'
|
||||
|
||||
const brainy = createAutoBrainy()
|
||||
|
||||
// Add text - automatically converted to vectors
|
||||
await brainy.addText('1', 'Machine learning is fascinating')
|
||||
await brainy.addText('2', 'Deep learning models are powerful')
|
||||
await brainy.addText('3', 'Cats make great pets')
|
||||
|
||||
// Search by meaning, not keywords
|
||||
const results = await brainy.searchText('AI and neural networks', 2)
|
||||
// Returns: machine learning and deep learning results
|
||||
```
|
||||
|
||||
## 🧠 What Auto-Configuration Does
|
||||
|
||||
When you use `createAutoBrainy()`, the system automatically:
|
||||
|
||||
### 🎯 **Environment Detection**
|
||||
- Detects Browser, Node.js, or Serverless environment
|
||||
- Configures threading (Web Workers vs Worker Threads)
|
||||
- Sets appropriate memory limits
|
||||
|
||||
### 💾 **Smart Storage Selection**
|

|
||||
|
||||
// Add user preferences as vectors
|
||||
await brainy.addVector({
|
||||
id: 'user1',
|
||||
vector: [0.8, 0.1, 0.9, 0.2], // [action, comedy, drama, horror]
|
||||
metadata: { name: 'Alice', age: 25 }
|
||||
})
|
||||
|
||||
await brainy.addVector({
|
||||
id: 'user2',
|
||||
vector: [0.1, 0.9, 0.2, 0.8],
|
||||
metadata: { name: 'Bob', age: 30 }
|
||||
})
|
||||
|
||||
// Find similar users
|
||||
const similar = await brainy.search([0.7, 0.2, 0.8, 0.1], 2)
