DynamoDB 跨区域复制 AWS Java SDK
DynamoDB cross-region replication AWS Java SDK
我需要为我的 DynamoDb 配置跨区域复制 table。要手动尝试，我只使用了 AWS Web 控制台，我在其中配置了具有适当区域的全局 Table 以通过 DynamoDb 流进行复制，这非常简单。有人可以告诉我如何使用 Java SDK 吗？
请记住，DyanmoDB 现在支持 global tables as announced on 29 November 2017。因此，您可能可以用全局表替换大量区域表。
Global Tables eliminates the difficult work of replicating data
between regions and resolving update conflicts, enabling you to focus
on your application’s business logic. In addition, Global Tables
enables your applications to stay highly available even in the
unlikely event of isolation or degradation of an entire region.
但是直接回答你的问题，它不是 AWS DynamoDB Java SDK 的一部分。您必须使用 AWS 实验室的 dynamodb-cross-region-library。
Cross-Region Replication
Important
AWS previously provided a cross-region replication solution based on
AWS CloudFormation. This solution has now been deprecated in favor of
an open source command line tool. For more information, please refer
to the detailed instructions on
GitHub:
https://github.com/awslabs/dynamodb-cross-region-library/blob/master/README.md
The DynamoDB cross-region replication solution uses the Amazon
DynamoDB Cross-Region Replication Library. This library uses DynamoDB
Streams to keep DynamoDB tables in sync across multiple regions in
near real time. When you write to a DynamoDB table in one region,
those changes are automatically propagated by the Cross-Region
Replication Library to your tables in other regions.
You can leverage the Cross-Region Replication Library in your own
applications, to build your own replication solutions with DynamoDB
Streams. For more information, and to download the source code, go to
