   @terrymanu @tuohai666 Hey guys, What do I found to be the cause of this problem is, the version of datasoure from Sharding-Proxy is "**5.6.0-Sharding-Proxy 4.0.0-RC2**", however, in the **ConnectionImpl** class of **mysql-connector-java**(5.1.44), it will automatically add @@query cache size if the version is lower than 8.0.3.
   
   It is suggested that the version of Sharding-Proxy can be configured by users or modified in other ways
