Add flag to disable timestamps cache; useful for optimizing environments with only natural ID queries
-----------------------------------------------------------------------------------------------------

                 Key: HHH-3480
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3480
             Project: Hibernate Core
          Issue Type: New Feature
          Components: caching (L2)
    Affects Versions: 3.3.0.SP1
            Reporter: Elias Ross
         Attachments: disable-ts-cache.txt

I've enabled the Hibernate query cache. And I've discovered that by using Criteria queries of "natural ID"s solely, there is little reason to replicate the timestamp cache; especially when using clustering.

I added a property setting disables the timestamp cache entirely. What happens in cases where a non-"natural ID" query is made is that the query simply occurs without caching at all, so this works fine.

This is a patch, applied against Hibernate 3.3 branch which allows for timestamp caching to be disabled, i.e., by setting:

hibernate.cache.use_timestamps_cache=false
