-------------------------------------
Summary: [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
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.
