Welcome

Hello, everyone!

The distributed database or middleware is so popular these days. If you are interested in this industry, then please have my welcome!

Apache ShardingSphere is an open-source ecosystem consisted of a set of distributed database middleware solutions. Based on that, I promise you will acquire a deep understanding of the distributed database and middleware.

Moreover, as an Apache TLP (Top level project), this community is open, diverse, and internationalized, which means you can enter into an entire open-source world and start your Apache community journey!

Last but not least, our mentors are experienced at the distributed system,  new SQL, and Java programming, since they worked or are working large-scale enterprises. Presently, they are preparing plenty of work for your coming! :-)

Introduction of Summer 2021

This is a program hosted by  ISCAS(Institute of Software Chinese Academy of Sciences) and openEuler community. It is very similar with Google Summer of Code.

It is the second time for ShardingSphere community to join this plan as the mentoring organisation.

Apache ShardingSphere has been selected as one mentoring organization, FYI. → [Community Application] Apache ShardingSphere community applies for Summer 2021

Apache ShardingSphere项目基本情况介绍

Apache ShardingSphere 是一套开源的分布式数据库解决方案组成的生态圈，它由 JDBC、Proxy 和 Sidecar（规划中）这 3 款既能够独立部署，又支持混合部署配合使用的产品组成。 它们均提供标准化的数据水平扩展、分布式事务和分布式治理等功能，可适用于如 Java 同构、异构语言、云原生等各种多样化的应用场景。

Apache ShardingSphere 旨在充分合理地在分布式的场景下利用关系型数据库的计算和存储能力，而并非实现一个全新的关系型数据库。 关系型数据库当今依然占有巨大市场份额，是企业核心系统的基石，未来也难于撼动，我们更加注重在原有基础上提供增量，而非颠覆。

Apache ShardingSphere 5.x 版本开始致力于可插拔架构，项目的功能组件能够灵活的以可插拔的方式进行扩展。 目前，数据分片、读写分离、数据加密、影子库压测等功能，以及 MySQL、PostgreSQL、SQLServer、Oracle 等 SQL 与协议的支持，均通过插件的方式织入项目。 开发者能够像使用积木一样定制属于自己的独特系统。Apache ShardingSphere 目前已提供数十个 SPI 作为系统的扩展点，仍在不断增加中。

ShardingSphere 已于2020年4月16日成为 Apache 软件基金会的顶级项目。
