Hi Community, federated query cannot query binary type data, none of the following types can be queried. + BIT + BINARY + VARBINARY + BLOB + LONGBLOB + MEDIUMBLOB ### Which version of ShardingSphere did you use? master mysql: 8.0 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC and ShardingSphere-Proxy ### Expected behavior  ### Actual behavior  ``` ERROR 30000 (HY000): Unknown exception.
