[GitHub] [arrow-datafusion] Dandandan commented on pull request #3228: Fix propagation of optimized predicates on nested projections

Dandandan commented on PR #3228:
URL: https://github.com/apache/arrow-datafusion/pull/3228#issuecomment-1229141748

   I'm not sure if this fixes the bug in issue #3073? I'm not totally convinced we should not propagate filters without column (e.g. constants), the result should remain the same whether it is propagated or not. Issue #3073 seems to be about a filter expression *with* a column, that somehow doesn't filter the row out.
   
   Could we add a test for #3073 here?
