Came up with something along these lines at my last place - not actually the hardest thing to do as long as you've got a robust & convenient locking system available to you. In my case I abused the common db instance that all the clients were connected to anyway to synchronize the callers on postgres advisory locks. Sure, this isn't the infinitely scalable, Netflix-scale solution that everyone is convinced they need for everything, but it will probably work absolutely fine for >90% of development scenarios. https://gist.github.com/risicle/f4807bd706c9862f69aa https://gist.github.com/risicle/f4807bd706c9862f69aa
