Explicitly include or exclude attributes

The DynamoDB Enhanced Client API offers annotations to exclude data class attributes from becoming attributes on a table. With the API, you can also use an attribute name that's different from the data class attribute name.

Exclude attributes

To ignore attributes that should not be mapped to a DynamoDB table, mark the attribute with the @DynamoDbIgnore annotation.

private String internalKey;

@DynamoDbIgnore
public String getInternalKey() { return this.internalKey; }
public void setInternalKey(String internalKey) { this.internalKey = internalKey;}

Include attributes

To change the name of an attribute used in the DynamoDB table, mark it with the @DynamoDbAttribute annotation and supply a different name.

private String internalKey;

@DynamoDbAttribute("renamedInternalKey")
public String getInternalKey() { return this.internalKey; }
public void setInternalKey(String internalKey) { this.internalKey = internalKey;}
