Maarten Breddels updated ARROW-9991:
------------------------------------
Summary: [C++] split kernels for strings/binary (was: [C++] split kernsl
for strings/binary)
> [C++] split kernels for strings/binary
> --------------------------------------
>
> Key: ARROW-9991
> URL: https://issues.apache.org/jira/browse/ARROW-9991
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Maarten Breddels
> Assignee: Maarten Breddels
> Priority: Major
>
> Similar to Python str.split and bytes.split, we'd like to have a way to
> convert str into list[str] (and similarly for bytes).
> When the separator is given, the algorithms for both types are the same.
> Python, however, overloads strip. When given no separator, the algorithm will
> split considering all whitespace (unicode for str, ascii for bytes) as
> separator.
> I'd rather see not too much overloaded kernels, e.g.
> binary_split (takes string/binary separator, and maxsplit arg, no special
> utf8 version needed)
> utf8_split_whitespace (similar to Python's version given no separator)
> ascii_split_whitespace (similar to Python's version given no separator, but
> considering ascii, although this could work on any binary data)
> there can also be rsplit versions of these, or they could be an argument.
