Description

https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/builds/39448469/job/96ja5h1b984ln09d

While it doesn't block anything, there's a warning (looks like because a parameter was misdeclared in the pxd file):

[33/36] Building CXX object CMakeFiles\_compute.dir\_compute.cpp.obj
_compute.cpp(18101): warning C4244: 'argument': conversion from 'int64_t' to 'uint32_t', possible loss of data
