Subject [jira] [Commented] (IGNITE-2795) Cache query cursor do not create value copy
Date Wed, 17 Aug 2016 12:27:20 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-2795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15424415#comment-15424415

Alexei Scherbakov commented on IGNITE-2795:


We already do no data copying before sending it to remote node. 

Concerning copy handling in GridH2ResultSetIterator wrapper for local queries I see only the
possibility to use marshaller for producing data copy
by serialize/deserialize process, which is less efficient than current approach requiring
only deserialization.

Are you sure we must implement copy handling in such way ?
