> [C++] Do not allocate memory for primitive outputs in CastKernel::Call
> implementation

> Key: ARROW-1896
> URL: https://issues.apache.org/jira/browse/ARROW-1896
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Wes McKinney
> Priority: Major
> Fix For: 0.13.0
>
>
> This is some refactoring / tidying. Unless an output of cast has a
> non-determinate size (e.g. is Binary or something else), the
> {{CastKernel::Call}} implementation should assume that it is writing into
> pre-allocated memory. The corresponding memory allocation can be lifted into
> the {{arrow::compute::Cast}} API
