用于对 DynamoDB 表进行读取、写入、更新和删除访问的 IAM policy

如果您需要允许应用程序创建、读取、更新和删除 Amazon DynamoDB 表、索引和流中的数据，请使用此策略。在适当的地方替换 AWS 区域名称、您的账户 ID 以及表名或通配符 (*)。

要将此政策扩展到涵盖该账户所有区域中的 AWS 所有 DynamoDB 表，请使用通配符 (*) 作为区域和表名。例如：

"Resource":[
                "arn:aws:dynamodb:*:123456789012:table/*",
                "arn:aws:dynamodb:*:123456789012:table/*/index/*"
                ]
