Hello, @Rachelint! As I understand, you worry about two questions: "Can `NULL` be an element in array?" and "May I implement DuckDB implementations rather ClickHouse?". I can not give you guarantees about null handling, because that problem has long history and lots of contradictions. If you interest about it, you can read the discussion in https://github.com/apache/arrow-datafusion/issues/7142#issuecomment-1693517988. Also, I would like to notice @jayzhan211 and his PR: https://github.com/apache/arrow-datafusion/pull/7338. The answer of the second question is predictably simple: you can use any methods if they have pragmatic value. I think I can answer all your questions. If you don't comprehend some situations, then you can ask me again :) -- This is an automated message from the Apache Git Service.
