When migrating from one inter.broker.listener.name to another broker by broker, what does happen to the inter broker communication during the time where the brokers in the cluster have a different inter.broker.listener.name configured?
Let's assume:
- Broker 1 & 2 use inter.broker.listener.name "internal"
- Broker 3 uses inter.broker.listener.name "external"
Will Broker 1 & 2 know how to connect to Broker 3 and vice versa / aka is a rolling update possible? If so how does it work (at a high level)?
