ArnavBalyan opened a new pull request, #8843:
URL: https://github.com/apache/paimon/pull/8843
### Purpose
- Data data evolution drops the rows when a column type/nullability changes
- This is because evolutionStats leaves the -1 offset for a column whose
stored type differs from the current type, which DataEvolutionArray encodes as
all null.
- LeafPredicate then prunes the pre alter version of the file and loses
rows.
- Correct such columns to the -2 so the file is kept
### Tests
- UT
