["Alexei Scherbakov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15352928#comment-15352928 ] 

Alexei Scherbakov commented on IGNITE-3385:
-------------------------------------------

For affinity key mapping it may generate single field annotated with @AffinityKeyMapped if only one field was selected by user
or delegate to AffnityKeyMapper for multiple selected fields like:

{code}
 private static class MyMapper implements AffinityKeyMapper {
        @Override public Object affinityKey(Object o) {
            if (o instanceof PersonKey)
                return new PersonAffkey(((PersonKey)o).getOrganizationId(), ((PersonKey)o).getManagerId()));
            return o;
        }

        @Override public void reset() {

        }
    }
{code}
