[GitHub] [calcite] wojustme commented on pull request #2686: [CALCITE-4982] NonNull field is pushed down into leaf of outer-join in 'ProjectJoinTransposeRule'

wojustme commented on PR #2686:
URL: https://github.com/apache/calcite/pull/2686#issuecomment-1273044390

   @libenchao 
   This issue/pr was so long that it took me a little time to review it.
   Two solutions:
   1. Avoid pushing down with the operand of coalesce's operator
   2. Keep pushing down, and fix `org.apache.calcite.plan.Strong#policy(org.apache.calcite.rex.RexNode)`
   
   Let's discuss in the [JIRA](https://issues.apache.org/jira/browse/CALCITE-4982)
