Quickstart

Usage

Basic Operations

1. Initialize and Start a Node

import asyncio
from vectrs.network import KademliaNode
from vectrs.database import VectorDBManager

async def start_node():
    # Initialize node
    node = KademliaNode(host='127.0.0.1', port=8468)
    db_manager = VectorDBManager()
    node.set_local_db_manager(db_manager)
    
    # Start node
    await node.start()
    
    # Optional: Connect to existing network
    await node.bootstrap('bootstrap_host', 8468)
    return node

# Run the node
node = asyncio.run(start_node())

1. Create Database

from vectrs.database.vectrbase import SimilarityMetric, IndexType

async def create_database(node):
    db_manager = VectorDBManager()
    # Create database with HNSW index
    db_id = db_manager.create_database(
        dim=384,  # Dimension of your vectors
        space=SimilarityMetric.COSINE,  # COSINE, L2, or other metrics
        max_elements=10000,
        index_type=IndexType.HNSW
    )
    return db_id

db_id = asyncio.run(create_database(node))

1. Vector Operations

import numpy as np

async def vector_operations(node, db_id):
    # Add single vector
    vector = np.random.rand(384).astype(np.float32)
    metadata = {"description": "example vector"}
    await node.add_vector(db_id, "vector1", vector, metadata)

    # Query vector
    results = await node.query_vector(db_id, "vector1", k=10)
    
    # Batch add vectors
    vectors = {
        "vec1": np.random.rand(384).astype(np.float32),
        "vec2": np.random.rand(384).astype(np.float32)
    }
    metadata_list = [{"desc": "vec1"}, {"desc": "vec2"}]
    await node.batch_add_vectors(db_id, vectors, metadata_list)
    
    # Update vector
    new_vector = np.random.rand(384).astype(np.float32)
    await node.update_vector(db_id, "vector1", new_vector, {"updated": True})
    
    # Delete vector
    await node.delete_vector(db_id, "vector1")

Graph Operations

async def graph_operations(node, db_id):
    # Add relationship between vectors
    await node.add_relationship(
        db_id, 
        "vector1", 
        "vector2", 
        relationship_type="similar_to"
    )
    
    # Get relationships
    relationships = await node.get_relationships(db_id, "vector1")
    
    # Graph-based query with depth
    results = await node.query_with_graph(
        db_id,
        "vector1",
        k=10,
        max_depth=2  # How deep to traverse relationships
    )

AI and RAG Features

from vectrs.swarms import Swarms

async def ai_operations(node):
    # Initialize Swarms with your Claude API key
    api_key = "your-anthropic-api-key"  # or use environment variable ANTHROPIC_API_KEY
    swarms = Swarms(
        node.db_manager, 
        host='127.0.0.1', 
        port=8468,
        anthropic_api_key=api_key
    )
    await swarms.initialize()
    
    # Run RAG workflow with a query
    result = await swarms.run_rag_workflow(
        query="What is the relationship between these vectors?"
    )
    # Result contains: query, retrieved_context, plan, generated_answer, reflection
    
    # Create and manage AI agent
    agent = await swarms.create_custom_agent(
        agent_type="reflection",  # Available types: reflection, tool, planning
        agent_id="agent1"
    )
    
    # Check agent status
    status = await swarms.get_agent_status("agent1")
    
    # Analyze complex task
    analysis = await swarms.analyze_task({
        "type": "complex_task",
        "data": "Analyze the economic impact of climate change"
    })
    # Analysis contains: required_skills, complexity, dependencies, estimated_duration

You can provide your Claude API key in three ways:

1. Pass it directly to the Swarms constructor

2. Set it as an environment variable: export ANTHROPIC_API_KEY=your-api-key

3. Use the CLI argument: python -m vectrs start-node --anthropic_api_key your-api-key

Advanced Features

Graphine Search

async def graphine_search(node, db_id):
    # Advanced graph-based similarity search
    results = await node.graphine_search(
        db_id=db_id,
        vector_id="vector1",
        k=10,  # Number of results
        ef=50   # Size of dynamic list for search
    )
    return results
