Your Kafka cluster has five brokers. The topic t1 on the cluster has:
Two partitions
Replication factor = 4
min.insync.replicas = 3You need strong durability guarantees for messages written to topic t1.You configure a producer acks=all and all the replicas for t1 are in-sync.How many brokers need to acknowledge a message before it is considered committed?
