Object Mapping for Composite Columns with Astyanax

1
votes

For example,

@Column("body")
private String body;

That will create a column "body"

I'd want to be able to annotate such that I can create a composite column such as "body:foo".

There isn't any example for this purpose or even any indication that this is possible. Does anyone have any more knowledge about this?

I'm not entirely sure that this will work with the entity persister, but I would maybe play around with something like:

@Column()
@Serializer(MyCompositeSerializer.class)
private SomeEntity entity;

public class MyCompositeSerializer extends AnnotatedCompositeSerializer<SomeEntity> {
    public MyCompositeSerializer() {
        super(SomeEntity.class);
    }
}

Take a look at how public class AnnotatedCompositeSerializer<T> extends AbstractSerializer<T> is implemented to get a feel for what you need to do if the above approach doesn't work.
