> +1 on @dramaticlly 's comment, changing the write distribution mode affects Spark job performance (causes heavy shuffle) when using Spark SQL like ``` DELETE FROM db_name.tbl_name WHERE date < '20220801' ``` or ``` UPDATE db_name.tlb_name SET col_a = NULL WHERE date <= '20220801' ``` setting `write.delete.distribution-mode`=`none` and `write.update.distribution-mode`='none' at table properties would reduce shuffle, but could affect other normal jobs writing to the same table. So having an option for specifying the write distribution mode would be ideal. -- This is an automated message from the Apache Git Service.
