Micah Kornfield created ARROW-8760:
--------------------------------------

             Summary: [C++] Add benchmarks for arrow/util/ rle_encoder.h for 
non-dictionary encodings.
                 Key: ARROW-8760
                 URL: https://issues.apache.org/jira/browse/ARROW-8760
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Micah Kornfield


[https://github.com/apache/arrow/pull/7143] is going to add benchmarks to 
arrow-reader-writer-benchmarks, but these only cover dictionary encoded cases.  
It is hard to force non-dictionary encoding so we should try to write some 
benchmarks that give a better sense of how that path changes with any algorithm 
changes.

 

It isn't clear how much this code path is exercised in practice so I'm not sure 
on the priority.
