<h1>关于 Apache ShardingSphere</h1>
<p>
<span class="colorOrange800">Apache ShardingSphere</span>
是一款开源分布式数据库生态项目，由 JDBC、Proxy 和
Sidecar（规划中） 3
款产品组成。其核心采用可插拔架构，通过组件扩展功能。对上以数据库协议及 SQL 方式提供诸多增强功能，包括数据分片、访问路由、数据安全等；对下原生支持 MySQL、PostgreSQL、SQL Server、Oracle
等多种数据存储引擎。Apache ShardingSphere
项目理念，是提供数据库增强计算服务平台，进而围绕其上构建生态。充分利用现有数据库的计算与存储能力，通过插件化方式增强其核心能力，为企业解决在数字化转型中面临的诸多使用难点，为加速数字化应用赋能。
</p>
<p class="colorOrange800 textBold">
ShardingSphere 已于2020年4月16日成为 Apache
软件基金会的顶级项目。
