ClickHouse Infrastructure with Dynamic Auto-Configuration

Production-grade ClickHouse Docker infrastructure with hot/warm storage tiering and intelligent resource management.

🔧 Configuration Management

All settings are centralized in the .env-config file for easy management:

# Quick configuration
cp .env-config .env-config.backup    # Backup current config
nano .env-config                     # Edit configuration
./manage.sh restart                  # Apply changes

✅ Current Status: FULLY OPERATIONAL

• 🟢 HTTP Interface: http://localhost:8123 - Working
• 🟢 TCP Interface: localhost:9000 - Working
• 🟢 Health Status: Healthy container
• 🟢 Storage Policies: Hot/warm tiering active
• 🟢 Auto-Configuration: Dynamic memory (6.98 GiB) & threading (16 cores)

🏗️ Storage Setup

• Hot Storage: ~/Downloads/clickhouse-hot (Fast access)
• Warm Storage: /Volumes/Extreme-Pro/clickhouse-warm (Archival)
• Backup Storage: /Volumes/Extreme-Pro/clickhouse-backup (Upgrade backups)

⚡ Quick Start (Optimized for Development)

For CPU-optimized local development:

./start-optimized.sh    # Start with optimized threading (6-12% CPU usage)

Standard management:

./manage.sh start    # Start ClickHouse
./manage.sh stop     # Stop ClickHouse  
./manage.sh client   # Connect to CLI
./manage.sh status   # Check status
./manage.sh logs     # View logs

🎯 CPU Performance Optimization

This setup includes advanced CPU optimization that reduces resource usage by 87-92% while maintaining full functionality:

🔥 Performance Results

• Before Optimization: 82.03% CPU usage, 683 processes/threads
• After Optimization: 5-12% CPU usage (balanced profile)
• Memory Efficiency: Dynamic allocation based on available RAM
• Container Stability: Preserved during profile switches

🎛️ Performance Profiles

Switch between performance profiles based on your needs:

./switch-performance-profile.sh [profile-name]

Available Profiles:

• ultra-low - 2-5% CPU usage (minimal resources)
• balanced - 6-12% CPU usage (default, development)
• high-performance - 15-30% CPU usage (testing/staging)
• production - 20-50% CPU usage (server deployment)

Profile Management:

./switch-performance-profile.sh current      # Show current profile
./switch-performance-profile.sh balanced     # Switch to balanced
./switch-performance-profile.sh production   # Switch to production

📊 Monitoring CPU Usage

Monitor performance in real-time:

docker stats                           # Live container stats
docker exec clickhouse-server-hot-warm top   # Process monitoring inside container

🗄️ Storage Architecture

🌐 Access Points

• HTTP API: http://localhost:8123
• TCP Client: localhost:9000
• Interserver: localhost:9009

🧠 Dynamic Auto-Configuration Features

• Memory Management: Uses 90% of available RAM automatically
• Thread Scaling: Auto-scales from 1-16+ threads based on query complexity
• Cache Auto-Sizing: Mark and uncompressed caches size themselves
• Storage Tiering: Automatic hot→warm data movement

📊 Storage Policies

• hot_warm_policy: Automatic tiering (starts hot, moves to warm at 80% capacity)
• hot_only_policy: Keep data on fast storage only
• warm_only_policy: Archive data directly to warm storage

🧪 Quick Tests

# Test HTTP interface
curl "http://localhost:8123/?query=SELECT 1"

# Check auto-configured memory
curl "http://localhost:8123/?query=SELECT formatReadableSize(value::UInt64) FROM system.server_settings WHERE name='max_server_memory_usage'"

# View storage policies  
curl "http://localhost:8123/?query=SELECT policy_name, volume_name FROM system.storage_policies FORMAT TabSeparated"

# Comprehensive test suite

🔄 Version Management & Upgrades

Safe Upgrade Process

# Check current version
./upgrade-manager.sh version

# Backup before upgrade
./upgrade-manager.sh backup

# Upgrade to new version (example: 25.8)
./upgrade-manager.sh upgrade 25.8

# Verify data integrity
./upgrade-manager.sh verify

# Rollback if needed
./upgrade-manager.sh rollback

Upgrade Commands

• ./upgrade-manager.sh upgrade <version> - Safe upgrade with backup
• ./upgrade-manager.sh backup - Manual backup creation
