- pyarrow.compute.array_sort_indices(array, /, order='ascending', *, null_placement='at_end', options=None, memory_pool=None)¶
Return the indices that would sort an array.
This function computes an array of indices that define a stable sort of the input array. By default, Null values are considered greater than any other value and are therefore sorted at the end of the array. For floating-point types, NaNs are considered greater than any other non-null value, but smaller than null values.
The handling of nulls and NaNs can be changed in ArraySortOptions.
Argument to compute function.
str, default “ascending”
Which order to sort values in. Accepted values are “ascending”, “descending”.
str, default “at_end”
Where nulls in the input should be sorted. Accepted values are “at_start”, “at_end”.
Alternative way of passing options.
If not passed, will allocate memory from the default memory pool.
