Andrii Vysotskiy updated KAFKA-15430: ------------------------------------- Description: I have configuration 5 nodes (KRAFT mode), with next roles: 4 broker+controller and 1 controller. Create topic with replication factor 5, and it is created, and describe show that topic partition have 5 replicas. {{/opt/kafka/latest/bin/kafka-topics.sh --create --bootstrap-server=dc1-prod-kafka-001-vs:9092 --replication-factor 5 --partitions 1 --topic test5}} /opt/kafka/latest/bin/kafka-topics.sh --describe --topic test5 --bootstrap-server=dc1-prod-kafka-001-vs:9092 Topic: test5 TopicId: amuqr8EgRmqeKryUHZwsMA PartitionCount: 1 ReplicationFactor: 5 Configs: segment.bytes=1073741824 Topic: test5 Partition: 0 Leader: 3 Replicas: 3,4,1,2,5 Isr: 3,4,1,2}} Replicas 5 and ISR 4. Why does kafka initially allow you to create a replica on the controller node, although in reality the replica is not created on the controller node and there are no topic files in the log directory. Is this expected behavior or not? Thanks. I want to understand whether such behavior is the norm for Kafka was: {*}{*}I have configuration 5 nodes, with next roles: 4 broker+controller and 1 controller.
