概述

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,以及对 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,而且仍在不断增加中。

ShardingSphere 已于 2020 年 4 月 16 日成为 Apache 软件基金会的顶级项目。 欢迎通过邮件列表参与讨论。

ShardingSphere Scope

ShardingSphere-JDBC

Maven Status

定位为轻量级 Java 框架,在 Java 的 JDBC 层提供的额外服务。 它使用客户端直连数据库,以 jar 包形式提供服务,无需额外部署和依赖,可理解为增强版的 JDBC 驱动,完全兼容 JDBC 和各种 ORM 框架。

  • 适用于任何基于 JDBC 的 ORM 框架,如:JPA, Hibernate, Mybatis, Spring JDBC Template 或直接使用 JDBC。
  • 支持任何第三方的数据库连接池,如:DBCP, C3P0, BoneCP, Druid, HikariCP 等。
  • 支持任意实现 JDBC 规范的数据库,目前支持 MySQL,Oracle,SQLServer,PostgreSQL 以及任何遵循 SQL92 标准的数据库。

ShardingSphere-JDBC Architecture

ShardingSphere-Proxy

Download Docker Pulls

定位为透明化的数据库代理端,提供封装了数据库二进制协议的服务端版本,用于完成对异构语言的支持。 目前提供 MySQL 和 PostgreSQL 版本,它可以使用任何兼容 MySQL/PostgreSQL 协议的访问客户端(如:MySQL Command Client, MySQL Workbench, Navicat 等)操作数据,对 DBA 更加友好。

  • 向应用程序完全透明,可直接当做 MySQL/PostgreSQL 服务端使用。
  • 适用于任何兼容 MySQL/PostgreSQL 协议的的客户端。

ShardingSphere-Proxy Architecture

ShardingSphere-Sidecar(TODO)

定位为 Kubernetes 的云原生数据库代理,以 Sidecar 的形式代理所有对数据库的访问。 通过无中心、零侵入的方案提供与数据库交互的的啮合层,即 Database Mesh,又可称数据库网格。

Database Mesh 的关注重点在于如何将分布式的数据访问应用与数据库有机串联起来,它更加关注的是交互,是将杂乱无章的应用与数据库之间的交互进行有效地梳理。 使用 Database Mesh,访问数据库的应用和数据库终将形成一个巨大的网格体系,应用和数据库只需在网格体系中对号入座即可,它们都是被啮合层所治理的对象。

ShardingSphere-Sidecar Architecture

ShardingSphere-JDBC ShardingSphere-Proxy ShardingSphere-Sidecar
数据库 任意 MySQL/PostgreSQL MySQL/PostgreSQL
连接消耗数
异构语言 仅 Java 任意 任意
性能 损耗低 损耗略高 损耗低
无中心化
静态入口

混合架构

ShardingSphere-JDBC 采用无中心化架构,适用于 Java 开发的高性能的轻量级 OLTP 应用;ShardingSphere-Proxy 提供静态入口以及异构语言的支持,适用于 OLAP 应用以及对分片数据库进行管理和运维的场景。

Apache ShardingSphere 是多接入端共同组成的生态圈。 通过混合使用 ShardingSphere-JDBC 和 ShardingSphere-Proxy,并采用同一注册中心统一配置分片策略,能够灵活的搭建适用于各种场景的应用系统,使得架构师更加自由地调整适合与当前业务的最佳系统架构。

ShardingSphere Hybrid Architecture
