🗄️ ClickHouse Schema

Bảng đã thiết kế:

  1. proxy_metadata (ReplacingMergeTree)

    • Lưu thông tin proxy: id, host, port, protocol, ip_version, country, etc.
  2. proxy_access_mapping (ReplacingMergeTree)

    • Mapping access_token → proxy_id với priority
  3. proxy_usage_logs (MergeTree)

    • Log sử dụng proxy với TTL 90 ngày
    • Partition by date
  4. proxy_stats_hourly (AggregatingMergeTree)

    • Aggregated statistics theo giờ
    • Materialized View tự động aggregate từ usage_logs

🎯 Các Strategies đã implement

1. Random Strategy

  • Pick ngẫu nhiên từ pool
  • Hỗ trợ filters: country, ip_version, protocol

2. Round Robin Strategy

  • Xoay vòng tuần tự
  • Sử dụng Redis để lưu index
  • Key format: smartpool:rr:{access_token}:{filter_hash}

3. Least Delay Strategy

  • Query từ proxy_stats_hourly
  • Chọn proxy có avg_response_time thấp nhất
  • Hỗ trợ filter theo target_domain

4. Adaptive Ranking Strategy

  • Tính điểm dựa trên success rates ở nhiều windows
  • Formula: rate_10 * 0.4 + rate_50 * 0.3 + rate_100 * 0.2 + rate_200 * 0.1
  • Query từ proxy_usage_logs

5. Alternative Strategy

  • Tìm proxy tương tự với referer_proxy
  • Cùng protocol, ip_version, country
  • Loại trừ chính referer_proxy

📊 Data Flow

Get Proxy Flow:

Client Service
    ↓
SmartPool.Proxy SDK (ISmartPoolClient)
    ↓ (gRPC hoặc HTTP)
API.SmartPool (SmartProxyGrpcService hoặc SmartProxyController)
    ↓
ProxyStrategyFactory.GetStrategy()
    ↓
IProxyPickStrategy.PickProxyAsync()
    ↓
ProxyMetadataRepository / ProxyLogRepository
    ↓
ClickHouse (proxy_metadata, proxy_stats_hourly)
    ↓
Return SmartProxyServer

Log Usage Flow:

Client Service
    ↓
SmartPool.Proxy SDK (LogProxyUsageAsync)
    ↓ (gRPC hoặc HTTP)
API.SmartPool
    ↓
ProxyLogRepository.LogProxyUsageAsync()
    ↓
INSERT INTO proxy_usage_logs
    ↓
Materialized View auto-aggregate → proxy_stats_hourly

🔧 Configuration

API Backend (appsettings.json):

{
  "ClickHouse": {
    "Host": "localhost",
    "Port": 8123,
    "Database": "smart_pool"
  },
  "Redis": {
    "Configuration": "localhost:6379"
  },
  "Kestrel": {
    "Endpoints": {
      "Http": { "Url": "http://0.0.0.0:5000" },
      "Grpc": { "Url": "http://0.0.0.0:5001", "Protocols": "Http2" }
    }
  }
}

Client SDK (appsettings.json):

{
  "SmartPool": {
    "Protocol": "Grpc",
    "Host": "localhost",
    "Port": 5001,
    "DefaultAccessToken": "your-token",
    "TimeoutMs": 30000
  }
}

📝 API Endpoints

gRPC (MagicOnion):

  • GetProxy(GetProxyRequest) → SmartProxyResponse
  • LogProxyUsage(ProxyUsageLogRequest) → bool
  • Ping() → string

HTTP REST:

  • POST /api/smart-pool/v1/SmartProxy/get-proxy
  • POST /api/smart-pool/v1/SmartProxy/log-usage
  • GET /api/smart-pool/v1/SmartProxy/strategies
  • GET /api/smart-pool/v1/SmartProxy/health
  • POST /api/smart-pool/v1/SmartProxy/proxy/upsert
  • POST /api/smart-pool/v1/SmartProxy/access-mapping/add

🧪 Testing

Unit tests đã được tạo cho:

  • RandomStrategy
  • AlternativeStrategy
  • ProxyStrategyFactory
  • SmartPoolClient configuration

📚 Documentation

Đã tạo các file README:

  • SMARTPOOL_README.md - Tổng quan hệ thống
  • src/Icomm.API.SmartPool/README.md - API Backend guide
  • src/Icomm.SmartPool.Proxy/README.md - SDK Client guide
  • src/Icomm.SmartPool.Tests/README.md - Testing guide

🚀 Next Steps

Để chạy hệ thống:

  1. Setup ClickHouse:

    clickhouse-client < src/Icomm.API.SmartPool/clickhouse_init.sql
    
  2. Setup Redis:

    redis-server
    
  3. Run API:

    cd src/Icomm.API.SmartPool
    dotnet restore
    dotnet run
    
  4. Use SDK in Client Service:

    services.AddSmartPoolClient(configuration);
    
  5. Test:

    cd src/Icomm.SmartPool.Tests
    dotnet test
    

Features Highlights

  • Dual protocol support (gRPC + HTTP)
  • 5 intelligent proxy selection strategies
  • ClickHouse for high-performance logging
  • Redis for round-robin state management
  • Automatic aggregation with Materialized Views
  • Comprehensive error handling
