Apache Kafka cleanup topics

If you want to clean up data from a topic and you don’t have any intermediate storage, it is easy to set the retention time to a few seconds and then wait until the cleanup process kicks in. After that, the retention time can be set to the default value:

./ --zookeeper localhost:2181 --alter --entity-type topics --add-config --entity-name <topic-name>
