changing kafka retention period during runtime

Question

With Kafka 0.8.1.1, how do I change the log retention time while it\'s running? The documentation says the property is log.retention.hours, but trying to change

Answer 1

The following is the right way to alter topic config as of Kafka 0.10.2.0:

bin/kafka-configs.sh --zookeeper  --alter --entity-type topics --entity-name test_topic --add-config retention.ms=86400000

Topic config alter operations have been deprecated for bin/kafka-topics.sh.

WARNING: Altering topic configuration from this script has been deprecated and may be removed in future releases.
     Going forward, please use kafka-configs.sh for this functionality`
