Dyanamodbtable的对象模型

Question

我是DynamoDB的新手 研究后，我得出结论，将一张表用于应用程序设计。

因此，我有一个DynamoDB表为 pk，sk，content＆lt;许多其他属性＆gt; 。
我在Java中的模型现在看起来像

@DynamoDBTable(tableName = “my-data")
public class MyData {

    @DynamoDBHashKey(attributeName = "pk")
    private String partitionKey;

    @DynamoDBRangeKey(attributeName = "sk")
    private String sortKey; 

    @DynamoDBAttribute(attributeName = "content")
    private String content; //non queried content, I’ll save as JSON


    //below are the attributes which I MIGHT want to queries on later maybe be I'll end up creating GSI or LSI

    @DynamoDBAttribute(attributeName = "field1")
    private String field1;
    @DynamoDBAttribute(attributeName = "field2")
    private String field2;
    @DynamoDBAttribute(attributeName = "field3")
    private String field3;
    @DynamoDBAttribute(attributeName = "field4")
    private String field4;
    @DynamoDBAttribute(attributeName = "field5")
    private String field5;
    @DynamoDBAttribute(attributeName = "field6")
    private String field6;
    @DynamoDBAttribute(attributeName = "field7")
    private String field7;

}

我想要的，
我想拥有另一个类别的类，让我们称其为 mySearchAbledata 将field1到field7。然后，我想在下面的 mydata 内部拥有 mySearchAbledata 。

@DynamoDBTable(tableName = “my-data")
public class KaleidoscopeData {

    @DynamoDBHashKey(attributeName = "pk")
    private String partitionKey;

    @DynamoDBRangeKey(attributeName = "sk")
    private String sortKey; // ISO 8601 time string

    @DynamoDBAttribute(attributeName = "content")
    private String content; //non queried JSON content  

     // ?? what annotation to use here       
    private MySearchableData mysearchableData;      

}

public class MySearchableData{

    private String field1;
    private String field2;
    private String field3;
    private String field4;
    private String field5;
    private String field6;
    private String field7;
}

问题是。 要使用的注释，以便从 mySearchAbledata 中将所有这些字段视为aws my-data 表中的属性表
