SmartSql 2.2.0.2

SmartSql - Documentation

0. Why ?

• Embrace the cross platform. DotNet Core, it's time！
• Based on Dapper, no more wheels are repeated. Dapper performance you know!

1. So SmartSql

• TargetFramework: .NETStandard,Version=v1.3
• SmartSql = Dapper + MyBatis + Cache(Memory | Redis) + ZooKeeper + R/W Splitting + ......

2. Feature

• 1 ORM
  • 1.1 Sync
  • 1.2 Async
• 2 XmlConfig & XmlStatement → Sql
  • 2.1 SmartSqlMapConfig & SmartSqlMap √ (Yes, you guessed that, like MyBatis, you separated SQL from the XML configuration.)
  • 2.2 Config Hot Update →ConfigWatcher & Reload (Configuration file hot update: when you need to change Sql, modify the SqlMap configuration file directly and save it.)
• 3 Read-write separation
  • 3.1 Read-write separation
  • 3.2 Election of the read database by weight
  • 3.3 读库故障检测,剔除
• 4 Logging √
  • 4.1 Base on Microsoft.Extensions.Logging.Abstractions (When you need to track the debugging when everything is so clear at a glance)
• 5 DAO
  • 5.1 DAO
  • 5.2 DAO Tool
    • 5.2.1 Template Xml & Entity & DAO
    • 5.2.2 Generate Tool
• 6 Query Cache
  • 6.1 SmartSql.Cache.Memory
    • 6.1.1 Fifo
    • 6.1.2 Lru
  • 6.2 SmartSql.Cache.Redis
  • 6.3 Cache transaction consistency
• 7 Distributed configuration plugin
  • 7.1 IConfigLoader
  • 7.2 LocalFileConfigLoader √ (Local file configuration loader)
    • 7.2.1 Load SmartSqlMapSource Xml √
    • 7.3.1 Load SmartSqlMapSource Directory √
  • 7.3 SmartSql.ZooKeeperConfig √ (Distributed configuration file loader by ZooKeeper)
