Wes McKinney created ARROW-9067:
-----------------------------------
Summary: [C++] Create reusable branchless / vectorized index
boundschecking functions
Key: ARROW-9067
URL: https://issues.apache.org/jira/browse/ARROW-9067
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Wes McKinney
Fix For: 1.0.0
It is possible to do branch-free index boundschecking in batches for better
performance.
I am implementing this as part of the Take/Filter optimization (so please wait
until I have PRs up for this work), but these functions can be moved somewhere
more general purpose and used in places where we are currently boundschecking
inside inner loops.
