Acks and Min.insync.replicas

The video tutorial provides an in-depth explanation of Kafka's acknowledgement settings: X=0, X=1, and X=all. It covers how each setting affects data safety and performance, with X=0 offering no response, X=1 providing leader acknowledgement, and X=all ensuring full replica acknowledgement. The tutorial also discusses the importance of Min Insync Replicas for data safety and how it interacts with these settings to prevent data loss.

What happens if the leader broker goes down before data replication occurs?

How does the setting of X = all affect latency in Kafka?

What error message does a producer receive if there are not enough replicas available?
