本文整理了Java中com.amazonaws.services.s3.model.Region类的一些代码示例，展示了Region类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Region类的具体详情如下：
包路径：com.amazonaws.services.s3.model.Region
类名称：Region

Region介绍

[英]Specifies constants that define Amazon S3 Regions.

Amazon S3 Regions allow the user to choose the geographical region where Amazon S3 will store the buckets the user creates. Choose a Amazon S3 Region to optimize latency, minimize costs, or address regulatory requirements.

Objects stored in a Amazon S3 Region never leave that region unless explicitly transferred to another region.

In Amazon S3, all the regions provides read-after-write consistency for PUTS of new objects in Amazon S3 buckets and eventual consistency for overwrite PUTS and DELETES.
[中]指定定义Amazon S3区域的常量。
Amazon S3区域允许用户选择Amazon S3存储用户创建的存储桶的地理区域。选择Amazon S3区域以优化延迟、最小化成本或满足监管要求。
存储在Amazon S3区域中的对象永远不会离开该区域，除非显式地转移到另一个区域。
在Amazon S3中，所有区域都为Amazon S3存储桶中新对象的PUT提供了读写一致性，并最终为覆盖PUT和删除提供了一致性。
