@sweetpythoncode yeah I believe if we disable the flag to `check_duplicate_files` , then it's really rely on caller to cherry-pick the right data using partition filter. So if same add-files procedure is called repeatedly, this will cause same files being added more than once. I feel having a check duplicate option with - error (exit on first duplicate found) - skip_import_if_same_name_found (skip if existing data file with same name found, import otherwise) - off (import every data files regardless) seem to be handy for problem described above. On the other hand, if we can have a dedicated deduplicated action/procedure, it also helps here (not just for import but also for other data quality protection) -- This is an automated message from the Apache Git Service.
