推荐答案

KSQL主题与Kafka主题的概念不同.KSQL主题是KSQL的一个内部概念，它表示kafka主题以及有关该主题的元数据，包括主题格式.由于我们不在外部公开KSQL主题，因此您不应在KSQL语句中使用它.如果要删除kafka主题，则应将其从kafka中删除.将来我们计划向KSQL添加主题管理功能.

KSQL topic is different concept than Kafka topic. KSQL topic is an internal concept for KSQL that represents a kafka topic along with metadata about that topic including the topic format. Since we do not expose KSQL topic externally you should not use it in KSQL statements. If you wanna delete a kafka topic, you should delete it from kafka. In future we plan to add topic management capability to KSQL.
