How Do I Reset Kafka Data?

You can reset Kafka data by deleting Kafka topics.

Delete a topic: kafka-topics.sh --delete --zookeeper ZooKeeper Cluster service IP address:2181/kafka --topic topicname
Query all topics: kafka-topics.sh --zookeeper ZooKeeper cluster service IP address:2181/kafka --list

After the deletion command is executed, empty topics will be deleted immediately. If a topic has data, the topic will be marked for deletion and will be deleted by Kafka later.
