For typical topic creation scenarios:
- Replication factor = 3
- min.insync.replicas = 2
- acks = all (ensures not only the leader receives the write, but also the
in-sync replicas)
Refer to "min.insync.replicas" section of
https://docs.confluent.io/current/installation/configuration/topic-configs.html

Hi,
To prevent data loss within a kafka cluster, it is recommend to set
replication factor to 2/3 with min.insync replica of 2 and acks = all
Hopefully this article can help provide further insight:
