Amazon DocumentDB 现在支持从 5.0.1 开始的引擎次要版本
Amazon Web Services · 2026-06-09 · via Recent Announcements

发布于: 2026年6月8日

Amazon DocumentDB(兼容 MongoDB)现在支持从 5.0.1 开始的引擎次要版本。此版本提供了增强的聚合功能,包括新的运算符($rand、$pow、$dateToParts、$dateFromParts)、用于监控实例的活跃连接数指标,以及 CloudWatch 中的精细命令级性能指标(find、insert、findAndModify、update 等)。有关所含内容的完整列表,请参阅发行说明。次要版本在同一主要版本中提供新功能和错误修复,使您可以更好地控制升级集群的时间和方式。我们建议升级到最新的次要版本,以享受这些性能增强、错误修复和新功能。

您可以在创建新集群时指定次要版本 5.0.1,也可以使用 AWS 管理控制台或 AWS CLI(通过包含 --engine-version 5.0.1 的 modify-db-cluster 命令)将现有的 5.0.0 集群手动升级到 5.0.1。一旦升级到较新的次要版本,就无法降级回以前的次要版本。从 5.0.0(LTS)升级到 5.0.1 可以让您获得最新功能和修复,但您将无法再使用 LTS 跟踪版本。如果尽量少升级是您的首要任务,您应继续使用 LTS 版本。有关更多信息,请参阅使用长期支持(LTS)版本

Amazon DocumentDB 引擎次要版本 5.0.1 已在提供 Amazon DocumentDB 5.0 的所有 AWS 区域推出。请参阅 Amazon DocumentDB 开发人员指南,了解有关次要版本升级和版本支持日期的更多信息。请在 Amazon DocumentDB 管理控制台中创建或更新完全托管式 Amazon DocumentDB 集群。
