SVN Commit: Bug#247022 improve high throughput performance

 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=247022

 

Changes:

• Optimized change policies to avoid additional isNew and backupClone checks.
• Fixed custom DeleteObjectQuery to only use full row for custom call, instead of always.
• Added flag to turn logging off entirely when set to OFF.
• Optimized deletion in unit of work to use descriptor query instead of new one.
• Add volatile check for isLoggedIn to DatabaseSession.
• Add some micro optimization of unit of work commit/merge.
• Deleted some dead code in change sets.
• Fixed DatabaseQuery getJPQLString (was loop).
• Fixed DeleteObjectQuery prepare, (was doing things in the wrong place).
• Some cleanup.
• Avoid preparing empty password in Login, store empty password as empty String.
• Replaced synchronization in EntityManagerFactory with volatile variables.
• Fixed emulated performance tests.
