Sounds slightly counterintuitive. What have you included in your architecture that requires synchronization?

well , i have an ID's generation table on my DB , that is resposible of generating the ID's of my entities according to some Custom rules , this process requires read and write to that table , so synchronization should be garanteed , Thanks

Database transactions and locks should do this for you. They're generally great at concurrency if you get the options right.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

Let the database handle that if possible.
Don't get me started about those stupid light bulbs.
