<h1 align="center"> ShardingCore </h1>
`ShardingCore` 是一个支持efcore 2.x 3.x 5.x的一个分库分表的一个简易扩展,针对dbContext实现了无感知开发,针对之前x.0.0.x版本目前在之前的分表功能上支持了分库功能。
目前x.1.0.x的所有版本都支持分库分表,在使用程度上极大的降低了代码侵入性保证开发时候的无感知使用。该框架是基于efcore的虽然没有像sharding-jdbc一样支持任意jdbc的实现，但是针对efcore下的框架基本上都适用,
`ShardingCore`是什么简单来说我认为他是目前最完美的efcore下的分表组件,支持所有的efcore支持的数据库(原则上),针对dbContext进行plus升级实现了无感知开发。
在使用程度上极大的降低了代码侵入性保证开发时候的无感知使用(和efcore原生dbcontext一样)。
该框架在分表数据下使用的而架构是流式聚合可以保证内存的稳定,而非内存迭代。
但是针对efcore下的框架基本上都适用,你以为这就完了吗shardingcore我可以说完美支持abp并且无侵入性。
最后如果喜欢本项目的话或者本项目对您有帮助的话麻烦[点我star github 地址](https://github.com/xuejmnet/sharding-core) ,也欢迎各位.neter交流。

该库的简介目前仅使用该库无法或者说难以实现自动建表,但是只需要配合定时任务该库即可完成24小时无人看管自动管理。该库提供了 [IShardingTableCreator](https://github.com/xuejmnet/sharding-core/blob/main/src/ShardingCore/TableCreator/IShardingTableCreator.cs)
作为建表的依赖,如果需要可以参考 [按天自动建表](https://github.com/xuejmnet/sharding-core/tree/main/samples/Samples.AutoByDate.SqlServer)
目前所有的demo可以参考 项目源码里面的Sample.SqlServer

## 优点
- [支持自定义分库、分表规则]
- [支持自定义分表规则]
- [支持任意类型分表key]
- [针对iqueryable的扩展方便使用]
- [对dbcontext扩展近乎完美]
- [支持分表下的连表] ```join,group by,max,count,min,avg,sum```
- [支持针对批处理的使用] ``` BulkInsert、BulkUpdate、BulkDelete```支持efcore的扩展生态
- [提供多种默认分表规则路由] 按时间按取模
- [支持针对批处理的使用] [EFCore.BulkExtensions](https://github.com/borisdj/EFCore.BulkExtensions) ...支持efcore的扩展生态
- [提供多种默认分表规则路由] 按时间,按取模 可自定义
- [针对分页进行优化] 大页数跳转支持低内存流式处理
## 缺点
- [暂不支持分库]
- [消耗连接]出现分表与分表对象进行join如果条件没法索引到具体表会生成```笛卡尔积```导致连接数爆炸,后期会进行针对该情况的配置
- [该库比较年轻] 可能会有一系列bug或者单元测试不到位的情况,但是只要你在群里或者提了issues我会尽快解决

创建DbContext必须继承IShardingTableDbContext

# 注意事项
该库的IVirtualDbContext.Set<T>使用asnotracking所以基本不支持跟踪,目前框架采用AppDomain.CurrentDomain.GetAssemblies();
该库的追踪是基于adonet的MARS(MultipleActiveResultSets=True;)所以基本不支持该特性的无法支持完美追踪
,目前框架采用AppDomain.CurrentDomain.GetAssemblies();
可能会导致程序集未被加载所以尽可能在api层加载所需要的dll
使用时需要注意
- 实体对象是否继承`IShardingEntity`
- 实体对象是否继承`IShardingTable`
- 实体对象是否有`ShardingKey`
- 实体对象是否映射配置已实现`IEntityTypeConfiguration<TEntity>`
- 实体对象是否已经实现了一个虚拟路由
- startup是否已经添加虚拟路由
- startup是否已经添加bootstrapper.start()
```c#
services.AddShardingSqlServer(o =>
{
o.ConnectionString = "";
o.AddSharding<SysUserModVirtualRoute>();
o.UseShardingCoreConfig((provider, config) =>
{
//如果是development就判断并且新建数据库如果不存在的话(ishardingentity不会被创建)
config.EnsureCreated = provider.GetService<IHostEnvironment>().IsDevelopment();
//ishardingentity表是否需要在启动时创建(如果已创建可以选择不创建)
config.CreateShardingTableOnStart = true;
});
});
```
- startup
```c#
var shardingBootstrapper = app.ApplicationServices.GetRequiredService<IShardingBootstrapper>();
shardingBootstrapper.Start();
```
# 计划
- [提供官网如果该项目比较成功的话]
- [开发更完善的文档]
- [支持分库]
- [支持更多数据库查询]
- [支持更多数据库查询完善]
# 最后
该框架借鉴了大部分分表组件的思路,目前提供的接口都已经实现,并且支持跨表查询,基于分页查询该框架也使用了流式查询保证不会再skip大数据的时候内存会爆炸,目前这个库只是一个刚刚成型的库还有很多不完善的地方希望大家多多包涵,如果喜欢的话也希望大家给个star.
