Hi David, Thanks for reply. However, I don't have problem with number of replicas. I have 3 brokers. And topics configured accordingly, especially __consumer_offsets
Topic:__consumer_offsets PartitionCount:50 ReplicationFactor:3 Configs:segment.bytes=104857600,cleanup.policy=compact,compression.type=producer And everything was working find for months, until today. Why would I want changing replication factor? To what value?
