> > `DataSaveMode` > > +1, @yzeng1618, Could you explain the difference between `file_exists_mode`, `DataSaveMode`, and `SchemaSaveMode`? Does the combined functionality of `DataSaveMode` and `SchemaSaveMode` include `file_exists_mode`? Differences: - SchemaSaveMode: directory/path-level, executed pre-write (create/recreate/error/ignore). - DataSaveMode: data-in-directory-level, executed pre-write (truncate directory, append, or fail if the directory already has data files). - file_exists_mode: commit-time, single-target-file-level behavior when renaming a temp file to the final file name (SKIP/OVERWRITE/FAIL on name collision). So SchemaSaveMode + DataSaveMode does not include file_exists_mode; they don’t cover commit-time rename conflicts for a specific final file name. -- This is an automated message from the Apache Git Service.
