If I have multiple clients subscribed to a pusher channel, can I have only one of them receive the message?

Question

I have a load balanced situation, in which I have multiple instances running. I'm subscribing to a channel in each instance, but I only want one of them to trigger when a message comes through.

Is there any way to accomplish this?

Answer 1

If you want to have different subscribers and some are only interested in a subset of the messages distributed by a your publisher. Then your messaging service must allow subscribers to specify the topics relevant for them and/or inspect the messages and specify the content they are interested in.

Answer 2

that kind of goes against pub/sub pattern. Even if you added a streaming application in between you channel and your clients, this will still need to read all messages to decide which one to filter out to different clients
