4. Key Features of Vector Database Architecture I have implemented

4.1 High-Dimensional Vector Storage

Vector databases are optimized for storing and retrieving high-dimensional vectors efficiently. These vectors can represent various types of data, such as images, text embeddings, or sensor data.

# Example of vector storage
vector = [0.1, 0.2, 0.3, ..., 0.999]  # High-dimensional vector
database.insert(vector_id, vector)

4.2 Similarity Search Algorithms

Vector databases implement advanced similarity search algorithms like Approximate Nearest Neighbor (ANN) search to quickly find the most similar vectors to a query vector.

# Example of similarity search
query_vector = [0.2, 0.3, 0.4, ..., 0.998]
similar_vectors = database.search(query_vector, k=10)  # Find top 10 similar vectors

4.3 Indexing Structures

Specialized indexing structures such as HNSW (Hierarchical Navigable Small World) or IVF (Inverted File) are used to optimize search performance in high-dimensional spaces.

# Example of index creation
index = HNSW(dim=1000, max_elements=1000000)
database.create_index(index)

4.4 Scalability and Distribution

Vector databases are designed to scale horizontally, allowing for distributed storage and parallel processing of queries across multiple nodes.

# Example of distributed query
results = database.distributed_search(query_vector, nodes=['node1', 'node2', 'node3'])

4.5 Real-time Updates

Many vector databases support real-time updates, allowing for dynamic addition, modification, or deletion of vectors without significant performance impact.

# Example of real-time update
database.update(vector_id, new_vector)
database.delete(vector_id)

Advanced vector databases can handle multi-modal data, allowing for the storage and querying of different data types (e.g., text, images, audio) in a unified manner.

# Example of multi-modal data insertion
database.insert(id1, text_vector, metadata={'type': 'text'})
database.insert(id2, image_vector, metadata={'type': 'image'})

4.7 Metadata Management

Vector databases often include robust metadata management capabilities, allowing for efficient filtering and organization of vector data.

# Example of metadata-based search
results = database.search(query_vector, filter={'category': 'electronics', 'price': {'$lt': 1000}})

4.8 Versioning and Time Travel

Some vector databases support versioning, allowing users to query historical states of the database or roll back to previous versions.

# Example of time travel query
historical_results = database.search(query_vector, timestamp='2023-08-30T12:00:00Z')

4.9 Hybrid Search Capabilities

Advanced vector databases often support hybrid search capabilities, combining vector similarity search with traditional database queries for more precise results.

# Example of hybrid search
results = database.hybrid_search(
    vector_query=query_vector,
    text_query="smartphone",
    filter={'in_stock': True}
)

4.10 Monitoring and Analytics

Robust monitoring and analytics tools are often integrated into vector database systems, providing insights into performance, usage patterns, and system health.

# Example of analytics retrieval
performance_metrics = database.get_analytics(metric='query_latency', timeframe='last_24h')

I have a comprehensive understanding of vector database architectures and their practical implementation, showcasing my expertise in this advanced field of database technology.

5. Code Snippets for Vector Database Integration

5.1 Python Integration

Here's a Python code snippet demonstrating how to integrate and use vector database features:

import vectordb

# Initialize the vector database
db = vectordb.connect(host='localhost', port=8080)

# Create a collection
db.create_collection('products', dimension=1024)

# Insert vectors
product_vector = [0.1, 0.2, ..., 0.9]  # 1024-dimensional vector
db.insert('products', id='prod001', vector=product_vector, metadata={'name': 'Smartphone', 'price': 999})

# Perform similarity search
query_vector = [0.2, 0.3, ..., 0.8]  # 1024-dimensional vector
results = db.search('products', query_vector, top_k=5)

# Update vector
db.update('products', id='prod001', vector=new_product_vector)

# Delete vector
db.delete('products', id='prod001')

# Perform hybrid search
results = db.hybrid_search(
    'products',
    query_vector=query_vector,
    filter={'price': {'$lt': 1000}},
    text_query='smartphone',
    top_k=5
)

# Close the connection
db.close()

5.2 JavaScript Integration

Here's a JavaScript code snippet showing how to integrate vector database features in a web application:

import VectorDB from 'vector-db-js';

// Initialize the vector database client
const db = new VectorDB({
  host: '<https://api.vectordb.com>',
  apiKey: 'your-api-key'
});

// Create a collection
await db.createCollection('images', { dimension: 2048 });

// Insert a vector
const imageVector = new Float32Array(2048); // 2048-dimensional vector
await db.insert('images', {
  id: 'img001',
  vector: imageVector,
  metadata: { filename: 'sunset.jpg', tags: ['nature', 'evening'] }
});

// Perform similarity search
const queryVector = new Float32Array(2048); // Your query vector
const searchResults = await db.search('images', {
  vector: queryVector,
  topK: 10,
  filter: { tags: 'nature' }
});

// Update a vector
await db.update('images', 'img001', {
  vector: newImageVector,
  metadata: { tags: ['nature', 'evening', 'beach'] }
});

// Delete a vector
await db.delete('images', 'img001');

// Perform hybrid search
const hybridResults = await db.hybridSearch('images', {
  vector: queryVector,
  text: 'beautiful sunset',
  filter: { tags: 'evening' },
  topK: 5
});

// Real-time updates using WebSocket
const subscription = db.subscribe('images', (update) => {
  console.log('Received update:', update);
});

// Unsubscribe when done
subscription.unsubscribe();

These code snippets demonstrate basic operations and advanced features of vector databases in both Python and JavaScript environments. They showcase how i have performed vector insertions, similarity searches, updates, deletions, and advanced querying capabilities.

    # Perform similarity search in the vector database
    similar_products = db.search('products', 
                                 query_vector=product_vector, 
                                 top_k=top_k, 
                                 filter={'in_stock': True})
    
    return [result['id'] for result in similar_products]

# Usage in recommendation API
@app.route('/recommend', methods=['GET'])
def get_recommendations():
    product_id = request.args.get('product_id')
    recommendations = recommend_similar_products(product_id)
    return jsonify(recommendations)

    if is_anomaly:
        trigger_alert(sensor_id)

# Usage in IoT data ingestion pipeline

def ingest_sensor_data():
    sensor_id = request.json['sensor_id']
    raw_data = request.json['data']
    process_and_store_sensor_data(sensor_id, raw_data)
