If have a root entity that has many owned one to many relationships
(say about 10), and each children collection can have hundreds or
thousands of child entities in them, something like:
public class Account{
@Persistent(mappedBy = "account")
@Order(extensions = @Extension(vendorName="datanucleus", key="list-
ordering", value="key asc"))
private List<Child1> children1;
@Persistent(mappedBy = "account")
@Order(extensions = @Extension(vendorName="datanucleus", key="list-
ordering", value="key asc"))
private List<Child2> children2;
//....
@Persistent(mappedBy = "account")
@Order(extensions = @Extension(vendorName="datanucleus", key="list-
ordering", value="key asc"))
private List<Child10> children10;
}
And this root entity has no custom indexes. Is it possible to get an
exploding index? Is this a bad design model for app engine or is this
okay?
I'm just not sure how app engine works with owned one-to-many
relationships in terms of indexes.
