Kafka officially provided two scripts to manage the topic, including additions and deletions to topic. Where kafka-topics.sh is responsible for the creation and deletion of topic, kafka-configs.sh script is responsible for topic modification and query, but many users are more inclined to use the program API to operate topic. The previous article mentioned how to

some time ago in the Kafka QQ Group was asked about this--about how Java consumer dynamically modify topic subscription issues. It's really a good question to think about it, because if you simply hold the consumer instance in another thread and then call subscribe to modify it, the consumer side will inevitably throw an exception Concurrentmodificationexception:kafkaconsumer is isn'tsafe for multi-threade
