Create topic. Delete topic. Make sure the topic deletion is enabled in the app configuration. Managing topics using Automation Script. You can perform a full set of topic management operations using Kafka Magic Automation Script. Topic management example:

The ability to delete a topic in a live, running kafka cluster is tricky, and the implementations of it have been subtly incorrect (and therefore dangerous). I know that there is work happening around that, but haven't kept up with the status of it.

It happened several times that some topics can not be deleted in our production environment. By analyzing the log, we found ReplicaStateMachine went wrong. A topic can be created by Principal A, then partitions can be added by Client 1, and finally it can be deleted by Principal B. This makes the accounting strange. That would work better if we would have a notion of tenant in Kafka. Kafka Topic Management. Kafka comes with its own topic management tools that can be downloaded from here. For our offering of Kafka 2.6.1 and newer, you can use Kafka-topics.sh tool that they have provided.

Note: This will have no impact if delete.topic.enable is not set to true. It can take some time to the topic to actually be deleted. Not that is is simply marked for deletion above. A process will come along periodically to purge marked paritions. This means that if you run a delete then --list you may see the topic still there for many minutes.

1、确保kafka的配置文件server.proeprties中设置delete.topic.enable=true，如果没有，确保cluster的所有kafka配置文件设置该参数并重启，然后直接通过命令删除，如果命令删除不了，直接通过zookeeper命令行删除掉broker下的topic。 We are using kafka 0.9 and delete.topic.enable=true is set .After we delete topic, it shows "marked for deletion" but it still shows under topic list. After restarting brokers, it is gone. Does that mean deleting a topic requires restart or some configuration property is missing.

This includes the cluster to connect and details about the records to delete. The records’ details can be specified in a json file passed to the tool using one of the switch.

kafka-topics --delete この場合は、KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1の設定をしてあげる必要があります。 We're running cluster of 3 kafka-0.8.2.2 nodes and delete.topic.enable is set to true on all nodes. Today we tried to delete one of the topics. I waited ~20 minutes after the kafka-topics.sh --delete was executed but the topic was still there.--describe showed Leader: -1 and only one of three brokers (1, 2 or 3) in ISR for all partitions. 之前有个 Kafka 集群的每个节点的挂载磁盘多达 20+ 个，平均每个磁盘约1T，每个节点的分区日志被平均分配到这些磁盘中，但由于每个分区的数据不一致，而集群节点 log.retention.bytes 这个参数的默认值是 -1，也就是没有任何限制，因此 Kafka 的日志删除日志依赖 log.retentio Kafka can serve as a kind of external commit-log for a distributed system. The log helps replicate data between nodes and acts as a re-syncing mechanism for failed nodes to restore their data. The log compaction feature in Kafka helps support this usage.

Since the broker 100 is down and currently unavailable the topic deletion has only been recorded in Zookeeper. Is topic deletion enabled at the broker level (delete.topic.enable=true) in the entire cluster, and did you restart it if you did enable it? Maybe since the disk is full, Kafka and related services are refusing to start. 调用kafka delete命令则无法删除该topic。同时，需要设置 auto.create.topics.enable = false，默认设置为true。如果设置为true，则produce或者fetch 不存在的topic也会自动创建这个topic。删除kafka topic及其数据，严格来说并不是很难的操作。但是，往往给kafka 使用者带来诸多问题，发现都会偶然出现无法彻底删除kafka的情况。前提：kafka必须配置参数delete.topic.enable=true. 如果需要被删除topic 此时正在被程序 produce和consume，则这些生产和消费程序 In Kafka, sometimes topics are marked for deletion.
