6.0.0
> [C++][Compute] Make GroupBy optimizations work on Big Endian architecture
> -------------------------------------------------------------------------
>
> Key: ARROW-12830
> URL: https://issues.apache.org/jira/browse/ARROW-12830
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Affects Versions: 4.0.0
> Reporter: Michal Nowakiewicz
> Priority: Major
> Fix For: 6.0.0
>
>
> This is related to ARROW-12010, which introduces optimized group by
> implementation.
> On s390x (big endian architecture) the code hangs in unit tests
> ([https://travis-ci.com/github/apache/arrow/jobs/506281680).]
> Currently this implementation is disabled on big endian and the alternative,
> earlier, implementation is used instead, but at some point we will stop
> maintaining both and switch to a single implementation, which requires fixing
> this issue.
