   > Could you please give more information about how would you like to use the truncate#width to create a ranger partition ? I did not quite understand your case actually. Thanks.
   
   From the iceberg document I found W is the width of each partition, not the number of partitions.
   If I want to divide the numbers from 1 to 100 into 3 ranger partitions, W should be 100/3 + 1 = 34 (because 100% 3 != 0).
   Do i have a misunderstanding?
   
   And then if I want to divide the numbers from Long.MIN_VALUE to Long.MAX_VALUE into 10 ranger partitions, W should be (Long.MAX_VALUE - Long.MIN_VALUE ) / 10 + 1 .
