      Lots of time is spent in sequential fashion to load dynamic partitioned dataset in driver side. E.g simple dynamic partitioned load as follows takes 300+ seconds

      INSERT INTO web_sales_test partition(ws_sold_date_sk) select * from tpcds_bin_partitioned_orc_200.web_sales;
      
      
      Time taken to load dynamic partitions: 309.22 seconds
