<h1 align="center"> ShardingCore </h1> <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。 `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。
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, 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。

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. 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.
