I got an "IllegalArgumentException: Too many indexed properties for
entity" Exception when saving an entity that looks like this:
...
@Persistent
@Element(dependent = "true")
@Order(extensions = @Extension(vendorName="datanucleus", key="list-
ordering", value="aDate asc"))
private List<ClassA> classAList; //ClassA only contains basic
properties like String and double
@Persistent
private double[] list1;
@Persistent
private double[] list2;
@Persistent
private double[] list3;
When I save an object, that has no more than 10 objects in classAList
and 3600 elements in each of the double[] Arrays list1-3 the error
above occurs in datastore.
I know that there exists a cap for indexed properties per entity of
max 5000. But I though this would only affect list porperties?
My question is, why are double arrays indexed? I thougt only List
Properties would be indexed?
Is double[] handled like List<Double> in app engines datastore?
