Neal Richardson commented on ARROW-12947:
-----------------------------------------
I don't know that it's accurate to say that it was agreed to increase the
minimum C++ standard to 14 or 17. Folks are exploring it but I don't think a
decision was reached.
> [Integration][C++] Upgrade all CI to use C++14
> -----------------------------------------------
>
> Key: ARROW-12947
> URL: https://issues.apache.org/jira/browse/ARROW-12947
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, Integration
> Affects Versions: 4.0.1
> Reporter: Niranda Perera
> Priority: Major
>
> Currently there is a CI step *rstudio/r-base:4.0-centos7*
> which runs GCC 4.8.1 (C++11).
> In the ML it was agreed that arrow would switch to >=C++14. Therefore, the CI
> step needs to be upgraded to a later GCC.
