Unfortunately, Go currently can only integrate with C++ libraries through a C
interface. There does exist SWIG which is a generator for creating interface
code between Go and C++, but ultimately it's just automating the creation of a
C interface
ementation, only for using the Dataset API stuff (and
potentially the compute library).

That's a fair point, and part of the work I've done so far is a local Go
implementation of at least consuming the C data interface. It will also
eventually involve creating the necessary implementation to produce the C-Data

Hi Matt,

Hi Matt,
As the name suggests, the C data interface is not a *programming*
interface. It is a data sharing convention which relies on the
existence of dedicated endpoints to produce or consume the C data
structures.
For example in Arrow C++, there is this set of APIs:

Hey All,
So I've been working on a use case where I needed to be able to use the Dataset
API from Golang and instead of trying to port all of it to Golang (which would
require porting the Compute side too) I decided to create a proof of concept
using CGO to just call into the existing C++ code
