Think of `native_iceberg_compat` as a variant of `CometScan` which uses the `Datafusion` reader instead of the original Comet parquet reader. Comet-Iceberg integration involves the iceberg scan replacing its own parquet file reader with the comet parquet reader. Iceberg w/Comet calls into the Comet scan's Batch reader and Column readers directly. `native_iceberg_compat` is written to provide a replacement for these classes. Neither `native_datafusion` nor `native_iceberg_compat` will (or can) integrate with `S3FileIO`. `S3FileIO` configuration is ignored if Comet is enabled in Iceberg. -- This is an automated message from the Apache Git Service.
