I will make this short, It is possible to update broker configurations dynamically with this command;
kafka-configs.sh
The entity-type can be topic, quota, brokers etc. but it cant be controller. That is not an option.
Since Kafka raft controllers are not really brokers and do not have advertised listeners. I assume it is not possible to update a setting like ssl.trustore.location dynamically on controllers.
Am I right in my thinking, did anyone tried and dynamically updated their controllers?
