Hello, >From Kafka Documentation - I understand that Authentication and encryption can be enabled for inter-broker, broker-client exchanges. By exchanges, i mean data transfer-related activities.
My questions are: 1) Is it common to have ONLY inter-broker and broker-client exchanges, but only plain transfer between zookeeper? in other words, is it common to only put authentication for brokers and clients, but not zookeepers. 2) If I also want to use authentication for zookeeper-zookeeper exchanges, is there any known performance issues I should be concerned about? I would be grateful if someone could provide a dummy example of having both implemented. I can see kafka online documentation which shows self-signing certificates and keystore usage for inter-broker and broker-client authentication, but I cannot see much mentioning of zookeeper to broker exchanges (may be i missed it). Kindest Regards, M. Manna
