pyarrow.compute.array_sort_indices

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.

Parameters:

arrayArray-like

Argument to compute function.

orderstr, default “ascending”

Which order to sort values in. Accepted values are “ascending”, “descending”.

null_placementstr, default “at_end”

Where nulls in the input should be sorted. Accepted values are “at_start”, “at_end”.

optionspyarrow.compute.ArraySortOptions, optional

Alternative way of passing options.

memory_poolpyarrow.MemoryPool, optional

If not passed, will allocate memory from the default memory pool.
