-----------------------------------------------------------------

[~h-vetinari] The Abseil discussion is not very interesting IMHO, because it's 
possible to require C\+\+17 only for GCS-enabled builds.

The important issue is about moving away from C\+\+11 for the _whole codebase_, 
i.e. adopt C\+\+17 features in Arrow C\+\+ itself, not just have an optional 
dependency which requires it.

> The upcoming abseil release has dropped support for C++11, so 
> {_}eventually{_}, arrow will have to follow. More details

> Relatedly, when I 
> [tried|https://github.com/conda-forge/abseil-cpp-feedstock/pull/25] to switch 
> abseil to a newer C++ version on windows, things apparently broke in arrow 
> CI. This is because the ABI of abseil is sensitive to the C++ standard that's 
> used to compile, and google only supports a homogeneous version to compile 
> all artefacts in a stack. This creates some friction with conda-forge (where 
> the compilers are generally much newer than what arrow might be willing to 
> impose). For now, things seems to have worked out with arrow 
> [specifying|https://github.com/apache/arrow/blob/897a4c0ce73c3fe07872beee2c1d2128e44f6dd4/cpp/cmake_modules/SetupCxxFlags.cmake#L121-L124]
>  C\+\+11 while conda-forge moved to C\+\+17 - at least on unix, but windows 
> was not so lucky.
> Perhaps people would therefore also be interested in collaborating (or at 
> least commenting on) this 
> [issue|https://github.com/conda-forge/abseil-cpp-feedstock/issues/29], which 
> should permit more flexibility by being able to opt into given standard 
> versions also from conda-forge.
