I am trying to setup a cluster where messages should never be lost once it is published. Say if I have 3 brokers, and if I configure the replicas to be 3 also, and if I consider max failures as 1, and I can achieve the above requirement. But when I post a message, how do I prevent kafka from accepting messages if there is only one server in this case? I see there is an option to specify "acks" to be all. I am not sure how does it work?
Thanks & Regards,
