KSQL - drop主题

Question

有没有办法从KSQL中删除这个主题？根据github的说法，这是可能的，我也尝试了

DROP TOPIC my-topic
DROP TOPIC "my-topic"
DROP TOPIC 'my-topic'
DROP TOPIC `my-topic`

但这两个命令都不起作用。我收到消息

 Message
-------------------------------------------------------------------------------
 io.confluent.ksql.util.KsqlException: No topic with name true was registered.
