[jira] [Commented] (IGNITE-3715) Incorrect Hibernate L2 cache statistics

["Wuwei Lin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15999696#comment-15999696 ] 

Wuwei Lin commented on IGNITE-3715:
-----------------------------------

getEntries() should return an empty set if not supported, as documented in Hibernate.
Loading all entries from all nodes is too expensive. I think we don't need to support this operation.

> These methods on {{SecondLevelCacheStatistics}} return incorrect data:
> * {{getElementCountInMemory()}} - returns only local node's cache size (zero on client), not the global cache size.
> * {{getEntries()}} - always returns empty map, even if there is data in cache.
