[GitHub] [arrow-datafusion] Jefffrey commented on pull request #5785: Planner: normalize_ident only when enable_ident_normalization is enabled

Jefffrey commented on PR #5785:
URL: https://github.com/apache/arrow-datafusion/pull/5785#issuecomment-1491812127

   > While working on this PR, I also noticed that there are places not related to the planner which also normalize names such as column. I wonder if it's valuable to also make these method configurable to enable ident normalization?

   I had some thoughts about this previously (not this specific function, but still applicable): https://github.com/apache/arrow-datafusion/pull/5183#discussion_r1096603578
   
   Generally I'm not sure how exactly to be able to toggle normalization at that level (the common crate) without API changes to dependent functions, like `from_qualified_name(...)` in `Column` as you've highlighted
