# Architecture Overview
|
||||
|
||||
Brainy is a multi-dimensional AI database that combines vector similarity, graph relationships, and metadata filtering into a unified query system. This document provides a comprehensive overview of the system architecture.
|
||||
|
||||
## Core Components
|
||||
|
||||
### BrainyData (Main Entry Point)
|
||||
The central orchestrator that manages all subsystems:
|
||||
- **HNSW Index**: O(log n) vector similarity search
|
||||
- **Storage System**: Universal storage adapters (FileSystem, S3, OPFS, Memory)
|
||||
- **Metadata Index**: O(1) field lookups with inverted indexing
|
||||
- **Augmentation System**: Extensible plugin architecture
|
||||
- **Triple Intelligence**: Unified query engine
|
||||
|
||||
### Triple Intelligence Engine
|
||||
Brainy's revolutionary feature that unifies three types of search:
|
||||
- **Vector Search**: Semantic similarity using HNSW indexing
|
||||
- **Graph Traversal**: Relationship-based queries
|
||||
- **Field Filtering**: Precise metadata filtering with O(1) performance
|
||||
|
||||
```typescript
|
||||
// Single query combining all three intelligence types
|
||||
const results = await brain.find({
|
||||
like: "machine learning papers", // Vector similarity
|
||||
connected: { to: "research-team", depth: 2 }, // Graph traversal
|
||||
where: { published: { $gte: "2024-01-01" } } // Metadata filtering
|
||||
})
|
||||
```
|
||||
|
||||
### Storage Architecture
|
||||
|
||||
```

|
||||
│ └── statistics.json

|
||||
├── verbs/ # Relationship storage
|
||||
├── wal/ # Write-Ahead Logging
|
||||
└── locks/ # Concurrent access control
|
||||
```
|
||||
|
||||
### HNSW Index
|
||||
Hierarchical Navigable Small World index for efficient vector search:
|
||||
- **Performance**: O(log n) search complexity
|
||||
- **Memory Efficient**: Product quantization support
|
||||
- **Scalable**: Handles millions of vectors
|
||||
- **Persistent**: Serializable to storage
|
||||
|
||||
### Metadata Index Manager
|
||||
High-performance field indexing system:
|
||||
- **O(1) Lookups**: Inverted index for field→value→IDs mapping
|
||||
- **Query Support**: equals, anyOf, allOf, range queries
|
||||
- **Chunked Storage**: Supports massive datasets
|
||||
- **Auto-indexing**: Automatically maintains indexes on updates
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Operation Complexity
|
||||
- **Vector Search**: O(log n) via HNSW
|
||||
- **Field Filtering**: O(1) via inverted indexes
|
||||
- **Graph Traversal**: O(V + E) for breadth-first search
|
||||
- **Add Operation**: O(log n) for index insertion
|
||||
- **Update Operation**: O(1) for metadata updates
|
||||
|
||||
### Memory Usage
|
||||
- **Base Memory**: ~50MB for core system
|
||||
- **Per Vector**: ~1KB (384 dimensions × 4 bytes)
|
||||
- **Index Overhead**: ~20% of vector data
|
||||
- **Cache Size**: Configurable (default 1000 entries)
|
||||
|
||||
### Throughput
|
||||
- **Writes**: 1000+ ops/second (with batching)
|
||||
- **Reads**: 10,000+ ops/second
|
||||
- **Search**: 100+ queries/second (varies by complexity)
|
||||
|
||||
## Augmentation System
|
||||
|
||||
Brainy's extensible plugin architecture allows for powerful enhancements:
|
||||
|
||||
### Core Augmentations
|
||||
- **WAL (Write-Ahead Logging)**: Durability and crash recovery
|
||||
- **Entity Registry**: High-speed deduplication for streaming data
|
||||
- **Batch Processing**: Optimized bulk operations
|
||||
- **Connection Pool**: Efficient resource management
|
||||
- **Request Deduplicator**: Prevents duplicate processing
|
||||
|
||||
### Creating Custom Augmentations
|
||||
```typescript
|
||||
class CustomAugmentation extends BrainyAugmentation {
|
||||
async onInit(brain: BrainyData): Promise<void> {
|
||||
// Initialize augmentation
|
||||
}
|
||||
|
||||
async onAdd(item: any, brain: BrainyData): Promise<any> {
|
||||
// Process item before adding
|
||||
return item
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Caching Strategy
|
||||
|
||||
Multi-layered caching for optimal performance:
|
||||
- **Search Cache**: LRU cache for query results
|
||||
- **Metadata Cache**: Field index caching
|
||||
- **Pattern Cache**: NLP pattern matching cache
|
||||
- **Entity Cache**: In-memory entity registry
|
||||
|
||||
## Integration Points
|
||||
|
||||
### Key Objects for Extensions
|
||||
- `brain.index`: Access HNSW vector index
|
||||
- `brain.metadataIndex`: Access field indexing
|
||||
- `brain.storage`: Access storage layer
|
||||
- `brain.augmentations`: Access augmentation manager
|
||||
|
||||
### Event System
|
||||
```typescript
|
||||
brain.on('add', (item) => console.log('Item added:', item))
|
||||
brain.on('search', (query) => console.log('Search performed:', query))
|
||||
brain.on('error', (error) => console.error('Error:', error))
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### When Adding Features
|
||||
1. Check if similar functionality exists
|
||||
2. Consider if it should be an augmentation
|
||||
3. Use existing indexes and caches
|
||||
4. Avoid duplicating functionality
|
||||
5. Follow the established patterns
|
||||
|
||||
### Performance Optimization
|
||||
1. Use batch operations for bulk data
|
||||
2. Enable appropriate caching
|
||||
3. Choose the right storage adapter
|
||||
4. Configure index parameters for your use case
|
||||
5. Monitor statistics for bottlenecks
