Maybe we can add new method `name()` same to `RaftVoterEndpoint#name`. in 4.x:
1) add `org.apache.kafka.common.Endpoint#name()` 2) deprecate `org.apache.kafka.common.Endpoint#listenerName()` 3) replace `org.apache.kafka.common.Endpoint` by `org.apache.kafka.network.Endpoint` in 5.x 1) remove `org.apache.kafka.common.Endpoint#listenerName()` Best, Chia-Ping On 2025/03/17 07:58:47 Ismael Juma wrote: > To be clear, that's not the only issue.
