[GitHub] [shardingsphere] liuheng1104 commented on issue #24257: How can we solve a large number of queries that contain in, if the parameter after in is large

URL: https://github.com/apache/shardingsphere/issues/24257#issuecomment-1436629064

   Our business is divided into 256 tables. Use the partition key (user_Id) to query in. The parameters are 100, and the logical sql is select * from table where user_ Id in (100 parameters), actual sql: select * from table_ 1 where user_ Id in (100 parameters), select * from table_ 2 where user_ Id in (100 parameters),
   
   Many parameters after in are invalid code scanning
