Yes, but I think the same of true

Hi Wes,
I think you highlighted the two issues well, but I think they are somewhat
orthogonal and runtime dispatching only addresses the binary availability
of the optimizations (but actually makes testing harder because it can
potentially hide untested code paths).
Personally, I think it is
Thanks Wes, I'm glad to see this feature coming.
From history talks, the main concern is runtime dispatcher may cause
performance issue.
Personally, I don't think it's a big problem. If we're using SIMD, it must be
targeting some time consuming code.
But we do need to take care some issues.
Hi,
I totally agree that arrow should has a built-in support for runtime
dispatching facilities just like other popular computing libs to fully utilize
the modern hardware capacity, we feel arrow has great potential performance
chance with the advanced cpu SIMD feature.
It's ok for me to
hi,
We've started to receive a number of patches providing SIMD operations
for both x86 and ARM architectures. Most of these patches make use of
compiler definitions to toggle between code paths at compile time.
This is problematic for a few reasons:
* Binaries that are shipped (e.g. in Python)
Just pushed the maint-0.17.x branch - I had conflicts here and there.
Applied the following git commands:
https://gist.github.com/kszucs/ea75f09090a9ffdff07e51582af1f436
Submitted the corssbow packaging tasks to see nothing is missing.
I'll start with cutting RC0 tomorrow.

As part of ARROW-8774 [1], I have created a Google doc [2] where any
interested parties can collaborate on a design discussion, which I will
then document in the JIRA.
