1. Introduction

1.1. Why

Embracing Cross-platform DotNet Core, it's time.
High performance, high productivity, ultra lightweight ORM. 156kb (Dapper:168kb)

1.2. So SmartSql

TargetFrameworks: .NETFramework 4.6 & .NETStandard 2.0
SmartSql = SmartSql = MyBatis + Cache(Memory | Redis) + ZooKeeper + R/W Splitting +Dynamic Repository + ......

1.3. Main feature

1 ORM
- 1.1 Sync
- 1.2 Async
2 XmlConfig & XmlStatement -> Sql
- 2.1 SmartSqlMapConfig & SmartSqlMap (Yes, you guessed it, like MyBatis, separating SQL via XML configuration.)
- 2.2 Config Hot Update ->ConfigWatcher & Reload (Configuration file hot update: When you need to modify the Sql, directly modify the SqlMap configuration file, save it.)
3 Read and write separation
- 3.1 Read and write separation
- 3.2 Multi-read library weight filtering (configure multi-read library, select read library according to read library weight)
4 Logging
- 4.1 Based on Microsoft.Extensions.Logging.Abstractions (when you need to track debugging, everything is so clear at a glance)
5 Dynamic Repository
- 5.1 SmartSql.DyRepository (Free your hands, you define the storage interface, I will implement database access)
6 Query cache (hot data cache, a configuration is easy to get)
- 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 (profile loader)
- 7.2 LocalFileConfigLoader (local file configuration loader)
  - 7.2.1 Load SmartSqlMapSource Xml
  - 7.3.1 Load SmartSqlMapSource Directory
- 7.3 SmartSql.ZooKeeperConfig (ZooKeeper Distributed Profile Loader)
