node.js - Redis Share Subscription mechanism to avoid multiple trigger onMessage event

Question

I would like to ask about any kind of mechanism that can handle Redis Share Subscription that is something much less like this https://www.emqx.io/blog/introduction-to-mqtt5-protocol-shared-subscription.

So now I had setup my Redis in docker environment. My application is running using NodeJs. As you might know, in docker environment I used replication mode for the app to cather high availibility.

Somehow this may cause a problem when the app replicated to two as redis subscription will be duplicated. So this problem caused Redis onMessage event triggered twice. So I believe I need to handle that multiple subscriber to only accept only once triggered event.

Can someone who are facing this same problem share some thought. Thanks!
