------------------------------------
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.
