KomachiSion commented on issue #2154: hikari datasource connection-test-query 
become useless

   The process of execute sql is 
   `Application --> ShardingDataSource(parse, route) --> printSQL if sql.show = 
true --> Hikari connection pool.`
   
   So the SQL`connection-test-query` set should not be print by ShardingSphere.
   the reason why your log print `ShardingSphere-SQL - Logic SQL: /* ping */ 
SELECT 1` may be something in your application invoke ShardingSphere to execute 
check/test SQL, such as `spring-boot-actuator`(detail see #2344 ).
   
   So I think it's not a problem for ShardingSphere
