- No support for `input_file_name()`, `input_file_block_start()`, or
`input_file_block_length()` SQL functions.
The `native_datafusion` scan does not use Spark's `FileScanRDD`, so these
functions cannot populate their values.
- No support for `ignoreMissingFiles` or `ignoreCorruptFiles` being set to
`true`
+- No support for duplicate field names in case-insensitive mode. When the
required or data schema contains
+ field names that differ only by case (e.g., `B` and `b`), Comet falls back
to Spark. Note that duplicates
+ in the physical Parquet file that are not reflected in the table schema
cannot be detected at plan time,
+ so DataFusion may produce a different error message than Spark in that case.
The `native_iceberg_compat` scan has the following additional limitation that
may produce incorrect results
without falling back to Spark:
