----------------------------
External issue URL: https://github.com/apache/arrow/issues/15403
> C++: establish a basic function evaluation model
> ------------------------------------------------
>
> Key: ARROW-34
> URL: https://issues.apache.org/jira/browse/ARROW-34
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Wes McKinney
> Assignee: Wes McKinney
> Priority: Major
> Fix For: 0.7.0
>
>
> We don't exactly have a working model for executing functions on Arrow
> objects that require memory allocations (either for intermediate storage of
> results).
> For example:
> F(input1, input2) -> output
> Since the output type may depend on the input types, F in general will need
> to be able to request memory to be allocated. This will have to be figured
> out (some sort of ArrowContext with a memory pool attached) in due course.
> For example:
> F(ctx, input1, input2) -> output
> Where ctx is a Context object provided access to memory resources and other
> system state (user-configurable).
