> Assignee: Andrew Mashenkov
> Fix For: 1.9

> Attachments:
> Change_keyIterator_to_entryIterator_for_local_scan_squery.patch, Demo.java
>
>
> I've found that ScanQuery use cache KeySet iterator which make cache

> It is look like we can avoid this calls by using EntrySet iterator for
> iterating over local partitions.
> Start point is GridCacheQueryManager.onheapIterator().
