apache-kafka - Kafkacat:如何删除主题或其所有消息？

Question

我正在寻找一种使用 kafkacat 删除主题或其所有消息的方法.
是否可能或唯一的方法是通过列出的脚本here ?

bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic mytopic

Answer 1

根据手册页和github源代码，kafkacat中现阶段没有删除主题功能。所以唯一的方法是使用 kafka-topics 脚本。

github source code

man page

kafkacat is a generic non-JVM producer and consumer for Apache Kafka 0.8, think of it as a netcat for Kafka.

 In producer mode ( -P ), kafkacat reads messages from stdin, delimited with a configurable
 delimeter and produces them to the provided Kafka cluster, topic and partition. In consumer
 mode ( -C ), kafkacat reads messages from a topic and partition and prints them to stdout
 using the configured message delimiter.

 If neither -P or -C are specified kafkacat attempts to figure out the mode automatically
 based on stdin/stdout tty types.

 kafkacat also features a metadata list mode ( -L ), to display the current state of the
 Kafka cluster and its topics and partitions.
