Ignite - Using - complex object with nested attributes and search

[M Singh]

Hi:
Can we insert a complex object into ignite cache and search it ?
Eg ( psuedocode ):public class Person {    int age,
    String name,
    List<Address> address,
    Tuple2<Person,Person> parents,
}
If it is possible, how can we annotated them ?  Also, can these nested 
attributes be used in SQL joins ?
Thanks
