--------------------------------------
Summary: [C++]Expose API for pushing down rep/def level
comparison down to decoder
Key: ARROW-8600
URL: https://issues.apache.org/jira/browse/ARROW-8600
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Micah Kornfield
[https://github.com/apache/arrow/pull/6985] shows the benefit of using SIMD for
level to bitmap conversion. We can do even better by exploiting RLE runs when
doing comparisons. Exposing an appropriate API and using that would likely
improve real world use-cases even further.
