Function arrow::compute::lexsort_to_indices
source ยท pub fn lexsort_to_indices(
columns: &[SortColumn],
limit: Option<usize>,
) -> Result<PrimitiveArray<UInt32Type>, ArrowError>
Expand description
Sort elements lexicographically from a list of ArrayRef
into an unsigned integer
(UInt32Array
) of indices.
Note: for multi-column sorts without a limit, using the row format may be significantly faster
