11moon11 opened a new pull request #1637: [CALCITE-3571] Disable RelBuilder#shouldMergeProject by default due to an exception
URL: https://github.com/apache/calcite/pull/1637
 
 
   RelBuilder#shouldMergeProject should be false by default, due to causing an exception when JOINs with complex conditions are involved.
   By complex condition I mean when joining on fields indirectly, ex: `ON (cast(query.empno as Integer) = cast(emp.empno as Integer))`.
