Question

我正在尝试从AWS实施Dynamodb Streams Java示例。我多次重复以下2个错误，然后程序按预期完成。任何想法是什么原因？

Answer 1

我们遇到了同样的问题，结果发现我们在设置中错过了区域，明确设置区域使其工作。

对于dynamodb-local，你不需要一个区域，所以使用它可以在没有区域的情况下工作，然后当你在AWS中部署它时，你将得到上述错误。

Answer 2

@ mikeal-sundberg提供的答案对我不起作用，我最终认为这与AWS与Dynamo local提供的端点之间存在差异。

使用Dynamo local，您可以为标准Dynamo客户端和AmazonDynamoDBStreams客户端使用相同的端点。部署后，AmazonDynamoDBStreams客户端需要特定于流的端点，例如https://streams.dynamodb.eu-west-1.amazonaws.com。
