🚀 Quick Start

Installation

# Install Kuzuk
pip install kuzuk

# Or install with enterprise features
pip install kuzuk[enterprise]

Basic Development Usage

import asyncio
from kuzuk import KuzukDriver

async def main():
    # Create a scalable driver with 3 read replicas
    driver = KuzukDriver(
        database_path="/path/to/database",
        replica_count=3
    )
    
    # Queries are automatically routed to optimal replicas
    result = await driver.execute_query("MATCH (n:Person) RETURN count(n)")
    print(f"Total persons: {result['data'][0]['count(n)']}")
    
    # Analytical queries use function shipping across all replicas
    analytics_result = await driver.execute_distributed_query(
        "MATCH (u:User)-[:PURCHASED]->(p:Product) "
        "RETURN u.country, sum(p.price) GROUP BY u.country"
    )
    
    await driver.close()

asyncio.run(main())

Core Scaling Patterns

1. Master-Replica Architecture

Write Operations: Single master ensures consistency
Read Operations: Distributed across multiple replicas
WAL Streaming: Real-time replication with <100ms lag
Automatic Failover: Master re-election and replica promotion

2. Function Shipping

Parallel Analytics: Execute on all replicas simultaneously
Result Aggregation: Smart merging of distributed results
Query Optimization: Automatic query plan distribution
Load Distribution: Balanced analytical workload execution

3. Intelligent Load Balancing

Health-Aware Routing: Automatic unhealthy replica avoidance
Response Time Optimization: Route to fastest replicas
Connection Pooling: Efficient connection management
Circuit Breaker: Automatic failure isolation
