How are managed mqtt connections in multiple replicas environment?

[neottil]

I am not very familiar with mqtt, but from what I understand you cannot have multiple open connections with the same clientID. From documentation (https://eclipse.dev/ditto/connectivity-protocol-bindings-mqtt.html#clientid) in the connection configurations you can specify the clientID to be used. However, how is the connection handled in a kubernetes scenario with multiple active replicas? It is not possible for each replica to use a different client, but with the same clientID, correct? So how do the different replicas present themselves to the broker? For completeness I specify that I am using configurations for mqtt 3.1.1.

Thank you
