ccoffline opened a new pull request #5106:
URL: https://github.com/apache/incubator-doris/pull/5106


   ## Proposed changes
   
   As #5105.
   For now these only affect `SELECT` statements. When handling `QueryStmt`, `StmtExecutor` will set limits to session variable, and set those back when the query is finished. So it won't take affect to `INSERT SELECT`.
