Amazon dynamodb dynamodbxcode6swift使用三列作为键,amazon-dynamodb,secondary-indexes,Amazon Dynamodb,Secondary Indexes,我正在尝试使用DynamoDB表存储此数据： DartSplayrinSultTable CustomerId String PlayerId String PlayerInsult String 使用此处描述的方法（概念，而非代码）： https://java.awsblog.com/post/Tx3GYZEVGO924K4/The-DynamoDBMapper-Local-Secondary-Indexes-and-You 在这里：在这里： http://labs.jo

我正在尝试使用DynamoDB表存储此数据：

DartSplayrinSultTable

CustomerId   String

PlayerId     String

PlayerInsult String

我希望每个客户播放器有多个侮辱记录。 CustomerId是我的哈希键 PlayerId是我的射程键我试图在一个键中使用PlayerResult，以便第二个playerResult值插入第二条记录而不是取代现有的

已经为此尝试了全局索引和二级索引，但如果我试图用一种新的侮辱来增加争吵，它仍然存在用相同的客户播放器密钥替换侮辱而不是添加一个新的

关于这方面最佳方法的任何建议如下： DynanoDB？是否需要为范围键创建混合列？尽量保持这个简单
