Michael Dick commented on OPENJPA-2017:
---------------------------------------
I've reverted these changes - since I was unable to build trunk (tests failed
in openjpa-lib). I'm not opposed to the changes, but I don't have the leisure
to resolve the testcase problem right now, please re-commit when the test
problem is resolved.
> Improve batch insertion performance

> Batch loading data is a common use case. Often, the user would not refer to
> the managed instances after the loading session. However, the runtime, by
> default, spends time in detaching the managed instances by creating/removing
> proxy or retaining state as per the configured options.
> An option should be provided to bypass these operations per persistence
> context basis.
> AutoDetach.NONE could be a possibility. This option will be exclusive i.e. it
> can not be specified with any other AutoDetach options. The NONE option will
> bypass proxying the fields at the transaction boundary or close.
