[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5326) UpdateTimestampsCache should maintain the statistics for its region

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37618#action_37618 ] 

Steve Ebersole commented on HHH-5326:
-------------------------------------

UpdateTimestampsCache is essentially a big map of entity-name to a timestamp.  The intent is that the timestamp indicates the last time any operation (*any* insert, update, delete) affected that entity.  So the statistics here would be across all entity/timestamp entries.

That being said...

How is it useful knowing that there have been 3,000,000 puts into this region (all operations on all entities)?

> Don't know if it is by design, but the SecondLevelCacheStatistics' for the UpdateTimestampsCache region are not maintained. Any idea why ?
