Logic for selection of advertised listener

[Dimos Raptis <di...@r3.com.INVALID>]

Hello,

I’ve been trying to understand the logic used to select one of the multiple advertised listeners (advertised.listeners) when connecting to a broker, but I couldn’t find a resource that explains exactly how it works.

In terms of inter broker communication, I believe this is done based on the value of the config option inter.broker.listener.name, i.e. the broker selects the listener that has the same name as the value of this option (right?).

However, it’s not completely clear how does a client select amongst all the advertised listeners for each of the brokers of a cluster. Does it just attempt to connect to all of them or is there some logic that defines which one will be selected?
Can you please explain? If there’s also any resource/docs that explains the mechanics of this, let me know.

Thanks,
Dimos
