[GitHub] [arrow-datafusion] alamb commented on pull request #2416: Fix bug in subquery join filters referencing outer query

alamb commented on PR #2416:
URL: https://github.com/apache/arrow-datafusion/pull/2416#issuecomment-1116849686

   >  I'm not sure why we're normalizing column names when building the logical plan rather than during optimization but this is the approach that the logical plan builder was already taking so I just kept things consistent to avoid any test regressions.
   
   I think this was part of @houqp 's work (maybe in  https://github.com/apache/arrow-datafusion/pull/1023) to properly handle multiple relations in a query
