Neal Richardson updated ARROW-7798:
-----------------------------------
Fix Version/s: 1.0.0
> [R] Refactor vector to Array conversion
> ---------------------------------------
>
> Key: ARROW-7798
> URL: https://issues.apache.org/jira/browse/ARROW-7798
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Francois Saint-Jacques
> Priority: Major
> Fix For: 1.0.0
>
>
> There's a bit of technical debt accumulated in this file:
> * Mix of conversion *and* casting, ideally we'd move casting out of there (at
> the cost of more memory copy). The rationale is that the conversion logic
> will differ from the CastKernels, e.g. when to raise errors, benefits from
> complex conversions like timezone... The current implementation is fast, e.g.
> it fuses the conversion and casting in a single loop at the cost of code
> clarity and divergence.
> * There should be 2 paths, zero-copy, non zero-copy. The non-zero copy should
> use the newly introduced VectorToArrayConverter which will work with complex
> nested types.
