Amazon DocumentDB(兼容 MongoDB)无服务器是 DocumentDB 的按需自动扩缩配置,现已在 8.0 版中推出。Amazon DocumentDB Serverless 可根据应用程序需求以细粒度的增量自动扩展或缩减容量,相比按峰值容量预置,最多可节省 90% 的成本。

DocumentDB 8.0 将查询延迟减少了最高 7 倍,压缩比提升了最高 5 倍,同时增加了与 MongoDB API 版本 6.0、7.0 和 8.0 的兼容性。它还引入了增强的向量搜索功能,索引构建速度最高提升 30 倍,新增了聚合阶段和运算符,并支持排序规则和视图。DocumentDB 无服务器在 Amazon DocumentDB 8.0 中可用于新集群和现有集群。

您可以使用就地主要版本升级(MVU)将 Amazon DocumentDB 5.0 集群转换为 Amazon DocumentDB 8.0 集群。要了解更多信息,请参阅升级 DocumentDB 集群。要了解有关已推出 Amazon DocumentDB 无服务器的区域的更多信息,请参阅按区域划分的支持的实例类。要了解有关 Amazon DocumentDB 无服务器的更多信息,请参阅概览文档AWS 新闻博客
