[GitHub] [arrow-datafusion] jayzhan211 commented on pull request #6796: Implement basic unnest function

jayzhan211 commented on PR #6796:
URL: https://github.com/apache/arrow-datafusion/pull/6796#issuecomment-1715666841

   The Unnest function is now processing in the planning step, Expr::Unnest to LogicalPlan::Unnest. Nothing to do in the optimize phase and only the existing UnnestExec is processed in the PhysicalPlan phase. Not sure if this is a good design but it works :)
   
   Maybe we can review the overall design, and then I will address the comments and resolve conflicts.
