   Thanks for reporting this @zhi-guo!  I have opened a bug ticket on the project JIRA: https://issues.apache.org/jira/browse/ARROW-14894
   
   In the short term, you can manually specify the `chunk_size` argument to `write_parquet()` to prevent this code from being run.  It governs how many rows of data are written to disk at once.  For a dataset with the rows/columns shown in your `cell_num` calculation above, around 2500000 is the value which would have been calculated.
