   Hi @hlf2016, thanks for your feedback, it should be related to this 
issue:https://github.com/apache/incubator-kvrocks/pull/930. Kvrocks will return 
an empty bulk string(`nil` for redis-cli), you can have a check if you have the 
empty key name like below:
   
   ```
   127.0.0.1:6666> get ""
   "1"
   ```
   And delete if this key was not expected, then the `nil` will be disappeared.
