Hello Avi, Yes, replication factor of 1 means just one lead replica gets assigned for the topic partitions.
To achieve HA of messages there are more things to watch out, not only replication factor - metadata/ZK HA, producer acks, min-in-sync replicas, rack awareness for replica assignment to name a few. See related talk from Kafka Summit http://kafka-summit.org/sessions/when-it-absolutely-positively-has-to-be-there-reliability-guarantees-in-kafka/ Kind regards, Stevo Slavic.
