Subject [jira] Created: (OPENJPA-1545) Add new Detach processing
Date Mon, 01 Mar 2010 23:26:05 GMT
Add new Detach processing
-------------------------

                 Key: OPENJPA-1545
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1545
             Project: OpenJPA
          Issue Type: Improvement
          Components: performance
            Reporter: Rick Curtis
            Assignee: Rick Curtis
         Attachments: OPENJPA-1545.patch

There have been a number of mailing list posts where the net of the post is that someone doesn't
want OpenJPA to detach their Entities because after the commit happens, then are all going
to be gc'd. All of the detach processing ends up being a waste.  I also observed this same
behavior when running some performance tests.

With this JIRA I'm going to add a new openjpa.DetachState configuration option which will
enable a new, super fast, minimalistic detach approach. This change is targeted at detach
processing that happens due to an AutoDetach. Explicit detaches(ie: em.detach(..) ) will work
as they always have before.
