----------------------------------------
Summary: [C++] Optimize Take and Filter
Key: ARROW-5760
URL: https://issues.apache.org/jira/browse/ARROW-5760
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Benjamin Kietzman
Assignee: Benjamin Kietzman
These kernels could probably make good use of scatter/gather SIMD instructions.
Furthermore, Filter's bitmap is currently lazily expanded into the indices of
elements to be appended to the output array. It would probably be more
efficient to expand to indices in batches, then gather using an index batch.
