Here is an update on tests that are ignored for `native_datafusion`.
- Issue #4316
- Cosmetic difference in error message format
- Issue #4354
- Cosmetic differeence in error reporting - diffferent exception nesting
in some cases
- Issue #4352
- Difference in type widening behavior when Spark vectorized reader is
disabled. PR #4355 is ready for review to solve this via fallback rule. Comet's
behavior is actually more correct than Spark's behavior in this case.
- Issue #4219
- Comet is more permissive than Spark 3.x when reading `TimestampNTZ`.
Comet matches Spark 4.x behavior. Draft PR to fix is #4357 (depends on upstream
fix https://github.com/apache/datafusion/pull/22318 which is already approved.
Not sure if this makes it into DF 54 or not. The current behavior is documented
and has been the default behavior since Comet 0.15.0
