That's also a costly option, however, because every time you iterate across the contents of the collection, you have to synchronize all operations, including read and write, to ensure consistency.

然而，这也是一个成本较高的选择，因为每当您跨集合内容进行迭代时，您就不得不同步所有操作，包括读和写，以此保证一致性。

If you've chosen to relax consistency, for example, then the developer needs to decide how to handle a situation where a write to the system is not immediately reflected in a corresponding read.

比如说，如果你选择放松一致性要求，那么开发人员就要决定怎样处理这种情形——对系统的写入不会立即反映到对应的读出中。

youdao

GSD provides read-after-write consistency which basically means that an object can be accessed - listed, downloaded, or deleted – right after uploading.

GSD提供了写后读的持久性，这意味着一个对象在上传后就可以访问了：列表、下载或是删除。
