I'm beginning to realise VertX does its event bus publishing (eventbus.publish) fanning out to all instances of all verticle subscribed. But if I use eventbus.send for a specific address, that message gets delivered to a single instance of the targeted verticle. My requirement is the ability to publish a message and get it delivered to a single instance of all subscriber verticles.
Simply put, publish a message and make sure it received by all subscribers but only one instance of a given subscriber.
I can build up intermediate component to handle this, but I'm looking for more out of the box option to resolve this.
P.S. I tried this on cluster mode as well with one docker per verticle and results are same.
