I have a play! app that runs a certain numbers of jobs. But the problem is, when we need a higher load on the server, we multiply the number of instance, thus our jobs are executed on every Play! servers.  

So I need to distribute those crons, but I don't really know where to start looking.  

I guess I'd need the equivalent of [Kue](http://learnboost.github.io/kue/) (that is for Node.JS), but don't know anything for Java, and even less for Play! 

Do you have any recommendations ?
