Sort order within a RowGroup of a leaf column

Fields

column_idx: i32

👎Deprecated since 57.0.0:

The format module is no longer maintained, and will be removed in 59.0.0

The ordinal position of the column (in this row group) *

descending: bool

👎Deprecated since 57.0.0:

The format module is no longer maintained, and will be removed in 59.0.0

If true, indicates this column is sorted in descending order. *

nulls_first: bool

👎Deprecated since 57.0.0:

The format module is no longer maintained, and will be removed in 59.0.0

If true, nulls will come before non-null values, otherwise, nulls go at the end.
