Good time of the day, We are using kafka 1.0.1, and want to create a permanent topic. One online post suggests setting retention.ms and retention.bytes to -1. The sample below shows system accepts -1 correctly, but I don't see this documented anywhere explicitly in the official documentation.
Could you confirm, and/or point me to the right official page? Thank you, Maxim kafka-topics.sh --create --zookeeper zk.local/kafka --replication-factor 3 --partitions 30 --topic maxim-test kafka-configs.sh --zookeeper zk.local/kafka --entity-type topics --entity-name maxim-test --alter --add-config retention.ms=-1 kafka-configs.sh --zookeeper zk.local/kafka --entity-type topics --entity-name maxim-test --alter --add-config retention.bytes=-1 --describe shows it as successful: zk.local Topic:maxim-test PartitionCount:30 ReplicationFactor:3 Configs:retention.ms=-1,retention.bytes=-1 Topic: msg-opt-in Partition: 0 Leader: 1 Replicas: 1,2,3 Isr: 1,2,3 Topic: msg-opt-in Partition: 1 Leader: 2 Replicas: 2,3,1 Isr: 2,3,1 Topic: msg-opt-in Partition: 2 Leader: 3 Replicas: 3,1,2 Isr: 3,1,2 Topic: msg-opt-in Partition: 3 Leader: 1 Replicas: 1,3,2 Isr: 1,3,2 Topic: msg-opt-in Partition: 4 Leader: 2 Replicas: 2,1,3 Isr: 2,1,3 Topic: msg-opt-in Partition: 5 Leader: 3 Replicas: 3,2,1 Isr: 3,2,1 Topic: msg-opt-in Partition: 6 Leader: 1 Replicas: 1,2,3 Isr: 1,2,3 Topic: msg-opt-in Partition: 7 Leader: 2 Replicas: 2,3,1 Isr: 2,3,1 Topic: msg-opt-in Partition: 8 Leader: 3 Replicas: 3,1,2 Isr: 3,1,2 Topic: msg-opt-in Partition: 9 Leader: 1 Replicas: 1,3,2 Isr: 1,3,2 Topic: msg-opt-in Partition: 10 Leader: 2 Replicas: 2,1,3 Isr: 2,1,3 Topic: msg-opt-in Partition: 11 Leader: 3 Replicas: 3,2,1 Isr: 3,2,1 Topic: msg-opt-in Partition: 12 Leader: 1 Replicas: 1,2,3 Isr: 1,2,3 Topic: msg-opt-in Partition: 13 Leader: 2 Replicas: 2,3,1 Isr: 2,3,1 Topic: msg-opt-in Partition: 14 Leader: 3 Replicas: 3,1,2 Isr: 3,1,2 Topic: msg-opt-in Partition: 15 Leader: 1 Replicas: 1,3,2 Isr: 1,3,2 Topic: msg-opt-in Partition: 16 Leader: 2 Replicas: 2,1,3 Isr: 2,1,3 Topic: msg-opt-in Partition: 17 Leader: 3 Replicas: 3,2,1 Isr: 3,2,1 Topic: msg-opt-in Partition: 18 Leader: 1 Replicas: 1,2,3 Isr: 1,2,3 Topic: msg-opt-in Partition: 19 Leader: 2 Replicas: 2,3,1 Isr: 2,3,1 Topic: msg-opt-in Partition: 20 Leader: 3 Replicas: 3,1,2 Isr: 3,1,2 Topic: msg-opt-in Partition: 21 Leader: 1 Replicas: 1,3,2 Isr: 1,3,2 Topic: msg-opt-in Partition: 22 Leader: 2 Replicas: 2,1,3 Isr: 2,1,3 Topic: msg-opt-in Partition: 23 Leader: 3 Replicas: 3,2,1 Isr: 3,2,1 Topic: msg-opt-in Partition: 24 Leader: 1 Replicas: 1,2,3 Isr: 1,2,3 Topic: msg-opt-in Partition: 25 Leader: 2 Replicas: 2,3,1 Isr: 2,3,1 Topic: msg-opt-in Partition: 26 Leader: 3 Replicas: 3,1,2 Isr: 3,1,2 Topic: msg-opt-in Partition: 27 Leader: 1 Replicas: 1,3,2 Isr: 1,3,2 Topic: msg-opt-in Partition: 28 Leader: 2 Replicas: 2,1,3 Isr: 2,1,3 Topic: msg-opt-in Partition: 29 Leader: 3 Replicas: 3,2,1 Isr: 3,2,1 -- *Maxim Kheyfets* Senior DevOps Engineer maxim.kheyf...@clearme.com | www.clearme.com
