xiaokang opened a new pull request, #23830: URL: https://github.com/apache/doris/pull/23830
## Proposed changes Issue Number: close #xxx `if (!new_top.is_null() && new_top != old_top)` is always false since old_top is Null when init and `Field == Null` always return true. We add old_top.is_null() check first to avoid the problem and then issue more carefull discussion about `Field == Null` semantics. ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
