------------------------------------

             Summary: Embedded / child element types indexing/queryfields (non-flat)
                 Key: IGNITE-2906
                 URL: https://issues.apache.org/jira/browse/IGNITE-2906
             Project: Ignite
          Issue Type: Improvement
          Components: cache, data structures, general, SQL
            Reporter: Krome Plasma


I've had discussion about this on Apache Ignite Users.

http://apache-ignite-users.70518.x6.nabble.com/Indexing-Querying-of-child-element-fields-td1704.html#a1734

The problem occurs when you want to index a non-primitive type that have same names of variables as the encloding type, better described on forum above. As a short example:

Let's say we want to index:

public class Person
{
 @QuerySqlField 
 long id;
 @QuerySqlField 
 PersonData personData;
}

public class PersonData
{
 @QuerySqlField 
 long id;
}

This will not work as it will detect indexes/query fields with same names for index Person.id and PersonData.id. As the names flatten.

I am attaching a simple patch that resolves this issue. We've been running this for (3 months now) and found no problems. However we are using annotations and not XML. I am not sure the patch completely solves the problem for XML based configuration.
