> [C++] Optimize strided WriteTensor
> ----------------------------------
>
> Key: ARROW-1457
> URL: https://issues.apache.org/jira/browse/ARROW-1457
> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Philipp Moritz
> Assignee: Wes McKinney
> Fix For: 0.7.0
>
>
> At the moment, if we call WriteTensor on a strided Tensor, it will write the
> tensor element by element; this can be optimized by combining multiple
> consecutive writes together.
> If there are long stretches of contiguous data, this might even be able to
> take advantage of the multithreaded memory copy we have int the
> FixedSizeBufferWriter.
