AWS 宣布推出兼容 DynamoDB 的开源适配器 ExtendDB
Amazon Web Services · 2026-05-21 · via Recent Announcements

发布于: 2026年5月20日

今天,Amazon Web Services(AWS)宣布推出 ExtendB 0.1 版,这是一个开源项目,可通过可插拔存储后端来实施 Amazon DynamoDB API。Amazon DynamoDB 是一个无服务器的完全托管式 NoSQL 数据库,在任何规模下均具有个位数毫秒级的性能。借助 ExtendDB,应用程序开发人员、平台团队和企业架构师能够在没有 DynamoDB 托管服务的环境中使用 DynamoDB 编程模型,包括开发人员笔记本电脑、本地数据中心和断开连接的边缘站点,而无需重新编写应用程序代码。

ExtendDB 实现了 DynamoDB 控制面板和数据面板 API,包括对表、项目和流的操作。发布时的参考存储后端为 PostgreSQL,其可插拔架构支持社区在不修改核心适配器的情况下添加新的存储后端。开发人员可以使用 ExtendB 进行高保真的本地开发和持续集成测试,并在由受支持数据库提供支持的本地数据中心中运行兼容 DynamoDB 的工作负载。

ExtendDB 由 AWS 负责维护,基于 Apache 2.0 许可证发布,并在 GitHub 上公开进行开发。我们邀请社区参与后端实现工作,提交反馈,一起推动项目的不断演进。要了解更多信息,请参阅 ExtendDB 项目页面和 AWS 数据库博客文章。要开始使用或贡献代码,请访问 GitHub 存储库
