Ariane Horbach commented on SPARK-54380:
----------------------------------------
Hey [~raisa], I'm interested in working on this issue. Before I start, I have a
few questions to ensure I approach this correctly:
* {*}Use case justification{*}: Could you describe a specific scenario where
placing nulls first would be beneficial? Alternatively, is there another
justification to consider, such as alignment with SQL standard behavior (e.g.,
{{{}ORDER BY ... NULLS FIRST/LAST{}}})?
* {*}Backward compatibility{*}: Should we maintain the current default
behavior (nulls last) to avoid breaking existing code? If so, would you support
adding a {{nulls_first}} parameter with a default value of {{{}False{}}}?
I am new contributor, so I want to make sure I understand the requirements and
align with the project's design principles before implementing this feature. I
appreciate any guidance you can provide!
