   Thanks @dramaticlly for opening this feature request
   In addition to the GDPR deletion use case, the column redaction use case would also benefit from setting `write.update.distribution-mode`='none' at the job level to avoid shuffles.
   
   Example SQL:
   ```
   UPDATE db_name.tlb_name SET col_a = NULL WHERE date <= '20220801'
   ```
