        ERDAT as order_date
    FROM sap_read_table('VBAK')
) TO 'az://your-container/sap-data/sales.parquet'
WITH HEADER;

Cloud Data Pipelines​

Automated Data Pipeline​

import duckdb
import boto3
from datetime import datetime

def extract_sap_data():
    """Extract data from SAP and upload to cloud"""
    
    # Connect to DuckDB
    conn = duckdb.connect('sap_pipeline.db')
    
    # Extract customer data
    customer_data = conn.execute("""
        SELECT 
            KUNNR as customer_id,
            NAME1 as customer_name,
            LAND1 as country,
            ORT01 as city
        FROM sap_read_table('KNA1')
        WHERE LAND1 = 'DE'
    """).fetchdf()
    
    # Upload to S3
    s3_client = boto3.client('s3')
    timestamp = datetime.now().strftime('%Y%m%d_%H%M%S')
    
    customer_data.to_parquet(f'/tmp/customers_{timestamp}.parquet')
    s3_client.upload_file(
        f'/tmp/customers_{timestamp}.parquet',
        'your-bucket',
        f'sap-data/customers_{timestamp}.parquet'
    )
    
    print(f"Uploaded {len(customer_data)} customer records to S3")

# Schedule this function to run daily
extract_sap_data()

Real-time Data Streaming​

import duckdb
import json
import boto3
from datetime import datetime

def stream_sap_data():
    """Stream SAP data to cloud in real-time"""
    
    # Connect to DuckDB
    conn = duckdb.connect('sap_streaming.db')
    
    # Get latest data
    latest_data = conn.execute("""
        SELECT 
            VBELN as sales_document,
            KUNNR as customer,
            NETWR as net_value,
            ERDAT as order_date
        FROM sap_read_table('VBAK')
        WHERE ERDAT >= CURRENT_DATE
    """).fetchdf()
    
    # Send to Kinesis
    kinesis_client = boto3.client('kinesis')
    
    for _, row in latest_data.iterrows():
        message = {
            'timestamp': datetime.now().isoformat(),
            'data': row.to_dict()
        }
        
        kinesis_client.put_record(
            StreamName='sap-data-stream',
            Data=json.dumps(message),
            PartitionKey=row['customer']
        )
    
    print(f"Streamed {len(latest_data)} records to Kinesis")

# Run every 5 minutes
stream_sap_data()

Best Practices​

Security​

  1. IAM Roles: Use IAM roles for service authentication
  2. Encryption: Encrypt data in transit and at rest
  3. VPC: Use VPC for network isolation
  4. Access Control: Implement proper access controls

Performance​

  1. Parallel Processing: Use multiple workers for large datasets
  2. Caching: Cache frequently accessed data
  3. Compression: Compress data for storage efficiency
  4. Monitoring: Monitor performance and costs

Cost Optimization​

  1. Right-sizing: Choose appropriate instance sizes
  2. Spot Instances: Use spot instances for non-critical workloads
  3. Reserved Capacity: Reserve capacity for predictable workloads
  4. Data Lifecycle: Implement data lifecycle policies

Reliability​

  1. Backup: Regular backups of critical data
  2. Disaster Recovery: Implement DR strategies
  3. Monitoring: Comprehensive monitoring and alerting
  4. Testing: Regular testing of failover procedures

Troubleshooting​

Common Issues​

  1. Network Connectivity: Check VPC and security groups
  2. Authentication: Verify IAM roles and permissions
  3. Performance: Monitor resource utilization
  4. Costs: Track and optimize cloud costs

Debugging​

import duckdb
import boto3

def debug_cloud_integration():
    """Debug cloud integration issues"""
    
    # Test DuckDB connection
    conn = duckdb.connect('debug.db')
    print("DuckDB connection: OK")
    
    # Test SAP connection
    try:
        result = conn.execute("PRAGMA sap_rfc_ping").fetchone()
        print(f"SAP connection: {result[0]}")
    except Exception as e:
        print(f"SAP connection error: {e}")
    
    # Test cloud connectivity
    try:
        s3_client = boto3.client('s3')
        s3_client.list_buckets()
        print("AWS S3 connection: OK")
    except Exception as e:
        print(f"AWS S3 connection error: {e}")
