########## docs/docs/spark/sql-write.md: ########## @@ -597,9 +599,9 @@ By default (`FORCE = FALSE`), COPY INTO tracks which files have been successfull ### Limitations +- **CSV column-count mismatch with ON_ERROR=CONTINUE**: Paimon follows Spark's PERMISSIVE mode behavior — rows with fewer columns are padded with NULL, and extra columns are silently ignored. These rows are loaded successfully and not counted as errors. Review Comment: The behavior described here conflicts with the implementation and the new tests below. `runTextImport` reads CSV with `_corrupt_record` in PERMISSIVE mode and `detectTextErrors` filters `corruptCol.isNotNull` as parse errors, while `CopyIntoOnErrorTest` expects fewer/extra columns to become `PARTIALLY_LOADED` with `errors_seen = 1`. So either this limitation should say these rows are skipped/count as errors, or the implementation/tests need to be changed to match the documented Spark PERMISSIVE behavior. -- This is an automated message from the Apache Git Service.
