[GitHub] [iceberg] gaojun2048 opened a new issue #3026: Is Iceberg support ranger partition?

In my case, I have a column named `id` and data type is `long` in my table. I want create ranger partition from `id` column.
I think the truncate's width (W) can do this. But the `W` only can be `Integer` now. Why not supported long type?

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 .
