["Valentin Kulichenko (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-2546?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Valentin Kulichenko updated IGNITE-2546:
----------------------------------------
    Description: 
Need to add new method to {{IgniteCache}} API:

{code}
public <T, R> QueryCursor<R> query(Query<T> qry, IgniteClosure<T, R> transformer);
{code}

For now this will be supported only for {{ScanQuery}}, for all others we should throw {{UnsupportedOperationException}} with proper message.

Example and documentation should be also added.

Need to add new method to {{IgniteCache}} API:

{code}

For {{SqlFieldsQuery}} we should throw {{UnsupportedOperationException}}, but for all other types of query proper support should be implemented.
